The standard timeline for receiving your hair test results via email is typically 5 to 7 business days from when we receive your hair sample. 

 

Should you require faster processing, we offer an expedited testing service. This involves delivering the hair sample to the forensic lab on the same day it’s collected and requesting the lab team to prioritise your sample. 

 

Please note, this expedited option is not available for tests initiated with a postal kit, as the acceleration process begins only once we have the sample in our possession. While we strive to meet your desired timelines by ensuring the lab receives the sample as swiftly as possible and placing an urgent request on your behalf, we cannot guarantee specific deadlines will be met. 

 

Expedited testing is not available after 5 pm on weekdays or during weekends and public holidays, and it incurs additional fees. To avoid any unforeseen delays, advanced planning is advised for a smooth and efficient testing experience.

It is generally estimated that substances such as drugs, alcohol, and steroids become detectable in head hair roughly 8-14 days after ingestion. This delay is predominantly due to the time required for the hair to grow above the scalp, allowing the substances to be captured in the hair strands.

Our laboratory is accredited by NATA (ISO 17025), the premier National Association of Testing Authorities in Australia, ensuring compliance with high standards of testing quality and reliability. This accreditation signifies our commitment to delivering high-quality, reliable testing services.

 

CASA Recognition: If you require the test for Civil Aviation Safety Authority (CASA) purposes, we recommend verifying with CASA to ensure our certification aligns with their specific requirements. It’s prudent to confirm this before proceeding to ensure full compliance with CASA’s standards.

International Recognition: For use overseas, it’s important to check with the relevant authorities in your country to determine if our accreditation meets their specific criteria. International standards and acceptance can vary, and direct confirmation from the respective body is advised to ensure the test results will be recognised.

Head Hair Analysis

Hair testing accurately reflects drug/alcohol/steroid use history up to 6 months (assuming 6cm of hair length is available to test). Since head hair grows approximately 1cm per month, it’s possible to examine individual monthly segments. For a recent three-month analysis, the initial 3cm nearest the scalp is tested; for six months, the next 3cm is analysed. 


This process, known as segmental testing, involves evaluating distinct hair lengths separately. To ensure precision, it’s best to predetermine the desired testing period, as longer durations may lead to less accurate results due to hair growth variability and the presence of dormant hair, which makes up 15% to 17% of scalp hair at any time.


For analysing a full 6cm, two 3cm segments are tested individually to avoid diluting drug concentrations over a larger sample. While 1cm or 2cm segments can be used for drug or steroid testing, alcohol testing is optimally conducted on 3cm segments.


Alcohol (EtG) Testing Distinction

It’s crucial to note the specific considerations for EtG (alcohol) testing. Per the Society of Hair Testing (SOHT) guidelines, the most reliable EtG results are obtained from 3 to 6 cm hair segments, a standard not applicable to Drugs of Abuse (DOA) or steroid testing. 


Testing EtG in hair shorter than 3 cm may not provide a reliable basis for interpreting results, given the scientific consensus and guidelines favour the 3 to 6 cm range. While EtG testing on 1cm samples is possible, the interpretive challenges of such short segments should be considered. We advise caution with EtG testing on hair shorter than 3 cm due to these potential limitations.


Before proceeding, especially for legal purposes, consult with legal experts to define the necessary timelines. The lab’s fee structure is based on each 3cm of hair length tested, highlighting the importance of clear communication regarding the testing scope.


Body Hair Considerations

The methodology for estimating drug exposure dates from body hair significantly differs from that of head hair, primarily due to body hair’s slower growth rate and higher proportion of dormant (telogen) phase hair. 


Each centimetre of body hair can represent up to 4 months of drug exposure, accounting for 1 month of growth plus 3 months of dormancy. Consequently, segmental testing for body hair, which would assess two separate time frames, is not feasible.


Given the complexities associated with body hair timelines and their potential impact on legal matters, head hair is strongly recommended for testing where possible. It’s crucial to discuss these aspects with your legal advisor before undergoing hair testing, as all fees for the service are non-refundable.

At our facility, we exclusively employ the internationally acclaimed gold standard for hair drug testing: Liquid Chromatography Mass Spectrometry (LCMS).

 

Understanding the distinction between the two prevalent types of hair drug tests is crucial, as it can significantly impact the outcomes relevant to your case.

 

The rapid enzyme-based test (immunoassay) is adept at identifying chronic users but is limited to a narrow spectrum of drugs (typically 5-12). In contrast, the more sophisticated mass spectrometry approach not only detects occasional or social drug users but also analyses over 70 different drug types, encompassing both illicit substances and prescription medications, in a single assessment.

 

By adhering to NATA-approved forensic laboratory testing protocols, which utilise mass spectrometry, we ensure a comprehensive and accurate representation of an individual’s drug intake history.

 

This method greatly reduces the risk of false negatives or positives, providing exoneration for the wrongly accused, identifying potential overprescription, and challenging the claims of irregular users.

 

Our commitment to precision and reliability in drug testing underscores our dedication to delivering conclusive and fair results.

 

Precision in Hair Analysis:

 

The laboratory advocates for segmental testing every 3cm of hair to maintain high accuracy levels. This method ensures that periods without drug activity don’t dilute the detection of active drug periods.

 

Testing larger segments could distort the actual concentrations, which is why a meticulous 3cm interval testing is adhered to.

 

For pinpoint accuracy, focus on the timeframe around your specific date of interest, extending roughly 2-3 weeks before and after.

 

It’s important to note that most forensic experts advise against analysing hair segments representing more than 6 months (or over 6cm of growth). This is due to the variability in hair growth rates and dormancy stages among individual follicles, which can lead to discrepancies over longer periods.

 

While requests to examine hair beyond the 6-month mark can be made, the decision to proceed rests with the forensic team. They weigh the potential for significant timeline inaccuracies, which could have legal implications.

 

The key takeaway is that the longer the hair segment tested, the greater the possibility for time-related variances.

 

Special Considerations for EtG (Alcohol) Testing:

 

It’s crucial to recognise the unique aspects of Ethyl Glucuronide (EtG) testing for alcohol consumption.

 

The Society of Hair Testing (SOHT) has set international guidelines suggesting the most reliable EtG test results come from analysing hair lengths between 3 to 6 cm.

 

This standard differs markedly from the testing protocols for Drugs of Abuse (DOA) or steroids, where the emphasis isn’t placed on this specific length range as you can test shorter periods such as 1 or 2 months (1-2 cm of growth) retrospectively.

 

The distinction is particularly significant because testing EtG in hair shorter than 3 cm might not provide a solid foundation for interpreting results.

 

The established scientific guidelines and consensus revolve around hair samples within the 3 to 6 cm length, making the interpretation of results from shorter hair lengths more challenging due to the absence of guidelines for these smaller segments.

 

Thus, while EtG testing on hair samples as short as 1 cm is technically possible, it’s essential to approach the interpretation of such results with caution due to the aforementioned limitations.

 

This advisory underscores the need for careful consideration when testing hair sections under 3 cm for EtG (alcohol) analysis.

We are committed to the highest standards of integrity in our hair sample collection and testing process, meticulously maintaining the chain of custody to ensure the reliability and credibility of our results.

 

 

Our protocol includes the following steps:

  1. Donor Identification: We initiate the process by authenticating the identity of the hair sample donor using a government-issued photo ID, such as a Driver’s License or Passport, to confirm the authenticity of the hair donor’s identification.

  2. Adherence to Global Standards: Our hair collection methodology is in strict compliance with the guidelines recommended by the Society of Hair Testing (SoHT), ensuring our practices meet international benchmarks.

  3. Sample Security: Following collection, the hair sample is secured with multiple tamper-evident seals, safeguarding the integrity of the sample from collection through to forensic analysis.

  4. Analysis by Accredited Laboratory: The secured hair sample is transported to the forensic laboratory, accredited by the National Association of Testing Authorities, Australia (NATA) and compliant with ISO/IEC 17025 standards. This ensures the lab’s proficiency in delivering precise and trustworthy analytical outcomes.

 

For those who are not locally based, a General Practitioner, with no personal or familial ties to the hair donor, can be appointed to undertake the hair collection. This collector is supplied with our hair collection kit, complete with detailed instructions to ensure the collection process’s accuracy and integrity.

 

 

Additionally, for clients seeking enhanced validation, our forensic team is prepared to furnish a detailed statement outlining the chain of custody and the analytical methods utilised, for a supplementary fee.

 

This documentation serves to thoroughly authenticate the management and examination of the sample, adding an extra degree of confidence and transparency to the entire testing procedure. It’s important to note that the cost for this extra service is contingent upon the particular demands and intricacy of the requested report.

The process of collecting hair for testing is designed to be both discreet and minimally invasive, involving the careful trimming of a small sample close to the scalp.

 

For the analysis to be considered valid, the collected sample needs to consist of approximately 120 strands, which equates to 100 milligrams or roughly the thickness of a shoelace tip. This sample is usually obtained from the crown of the head for consistency.

 

 

We understand that undergoing a hair substance test can be a source of anxiety and emotional discomfort. Our priority is to ensure the process is as stress-free and comfortable as possible. When it comes to cutting hair, especially from visible areas, we take great care to do so strategically, minimising visibility to maintain your privacy and dignity. Our team has heard concerns about distressing experiences elsewhere, but we want to reassure you that we approach this process with the utmost sensitivity and respect, aiming to alleviate any undue stress.

The decision to use head or body hair for testing substances like drugs, alcohol, or steroids is crucial due to their differing growth characteristics, which directly influence result analysis.

 

Head Hair Analysis: Head hair is the gold standard for substance testing, growing at a steady rate of approximately 1cm per month.

This uniform growth rate enables forensic toxicologists to estimate substance use timelines with greater precision from the hair sample’s length.

Typically, a 3cm segment of head hair can reflect up to three months of substance use retrospectively.

 

Body Hair Considerations: Body hair analysis introduces greater complexity. Although it may seem to grow at the same rate as head hair, body hair has a significantly larger proportion of dormant (telogen phase) hairs, which can stay inactive for up to three months before shedding.

 

As a result, a single centimeter of body hair might indicate up to four months of exposure to substances, considering 1 month of active growth plus 3 months of dormancy.

Timelines from body hair are thus estimated by measuring the average length and adding three months to account for the potential dormancy period.

 

Given these intricacies, head hair is the preferred sample for substance testing, especially in legal scenarios, due to its ability to provide more straightforward and accurate timelines.

Consulting with legal counsel before opting for body hair testing is advised, as the sample site choice could greatly impact result interpretation, and testing fees are non-refundable.

 

Preferred Sample Collection:

  • Head Hair: The preferred source due to its consistent growth, offering clearer insights into the timing of drug/alcohol/steroid use.
  • Body and Facial Hair (e.g., Underarm, Beard, Pubic Hair): Considered when head hair is unavailable, requiring about 2 full tablespoons for sufficient testing material.

 

In conclusion, while both head and body hair can serve as testing samples, head hair’s reliable growth rate makes it the superior choice for accurately determining substance use timelines, particularly relevant in legal contexts.

Our standard hair test report deliver concise and straightforward findings, detailing the exact substances identified with their detected concentrations measured in pg/mg.

 

This meticulous enumeration includes a broad array of substances, ensuring a thorough screening.

The layout of the report is designed for clarity, prominently displaying the test results for each screened substance as either positive or negative.

 

This format refrains from offering additional interpretations or delving into the broader implications of the detected substances.

 

The interpretation of these results, particularly when positive, involves complexities that extend beyond the basic numerical data provided. Understanding the significance of detected levels in relation to patterns of substance use, frequency, dosage, or specific timelines demands specialised forensic expertise.

 

Hair analysis serves as a durable record of substance exposure, capturing data over extended periods. However, understanding meaningful insights relevant to the hair donor regarding usage patterns from this data is intricate and often requires professional interpretation to fully understand the implications of the test results.

 

For those who receive a positive result, or for cases where a deeper analysis is required, consulting with our forensic specialist Dr Michael Robertson is recommended to navigate the intricacies of the findings and their potential implications.

Detectability of Infrequent Drug Use: The question of whether sporadic drug use will register in a hair test is complex. Generally, for a single or occasional use under “normal” dosing conditions, detection is less probable due to the “dilution” effect over a standard three-month test period. However, the likelihood of detection increases with the intensity and frequency of use. Remarkably, in instances like drug-facilitated sexual assault, even a one-time use can be identified, highlighting the test’s sensitivity.

 

Guaranteeing Detection of Single Exposures: While our testing can identify single exposures, a definitive positive result cannot be assured for every case. The nuanced nature of hair testing underscores the importance of understanding these limitations.

 

Impact of Chemical Hair Treatments: Treatments such as bleaching or dyeing can influence drug detectability in hair. The impact varies depending on the drug, the type of chemical treatment, and its intensity. Our experience shows that even extensively treated hair can often yield positive results, attesting to the robustness of our testing protocols.

 

Effect of Hair Age on Results: Testing hair segments representing more than 6 months can lead to diluted drug concentration readings. To mitigate this, we analyse such growth in two 3cm segments, ensuring a more accurate representation of drug use.

 

Adjusting for Hair Growth Timing: Accounting for the time hair takes to emerge above the scalp, we recommend extending the testing period by 2 weeks around the suspected drug use timeframe to enhance result accuracy.

 

Influence of Hair Colour: Darker hair, due to its higher melanin content, may bind more drug metabolites, potentially showing elevated detection levels compared to lighter natural hair shades.

 

Hair Drug Testing Techniques Explained: The landscape of hair drug testing is marked by distinct methodologies, each with its own set of capabilities and limitations. The enzyme-based immunoassay, known for its rapid and cost-effective analysis, is tailored primarily for identifying consistent drug users, with a focus on a limited range of 5 to 9 substances. However, this method’s notable drawback lies in its susceptibility to inaccuracies, such as false positives and negatives, which can significantly distort the true picture of an individual’s drug use history.

In response to these limitations, our clinic has made a decisive move towards the superior accuracy and expansive scope of mass spectrometry. This method stands out for its ability to detect a wide spectrum of over 70 substances, encompassing both illegal drugs and prescription medications. With its remarkable sensitivity—down to 1 pg/mg—mass spectrometry redefines the standards of precision in drug detection, ensuring even the most sporadic drug use does not go unnoticed.

Our exclusive commitment to mass spectrometry stems from a profound understanding of its benefits over immunoassays. By moving beyond methods that predominantly capture long-term drug use and are prone to error, we guarantee our clients a level of reliability and depth in analysis that is unparalleled.

This strategic choice is not just about superior technology; it reflects our deep commitment to providing the most thorough and accurate drug use analysis available. Our approach not only enhances the quality of our services but also instills a sense of confidence and clarity in our clients, which is especially crucial in contexts requiring indisputable accuracy, such as judicial proceedings.

 

Opting for NATA-Approved Forensic Analysis: By conducting our mass spectrometry analyses under the rigorous NATA-approved forensic standards, we ensure an exhaustive evaluation of drug consumption patterns. This meticulousness is key in scenarios where the stakes are high—whether it’s exonerating an individual wrongfully accused, identifying instances of prescription drug misuse, or detecting occasional drug use. It’s this level of precision that upholds the integrity and reliability of our test results, making hair drug testing a trusted cornerstone in forensic analysis.

Choosing a laboratory that aligns with these high standards is essential for circumventing the pitfalls of false results, thereby maintaining the credibility and essential role of hair drug testing in both forensic science and broader drug detection efforts.

Ceasing the use of drugs, alcohol, or steroids doesn’t immediately negate the possibility of a positive test result. This is due to the enduring presence of these substances and their metabolites in hair, which can be influenced by factors such as individual metabolism, hair colour, cosmetic treatments, and the specifics of substance use, including its concentration, quality, and frequency.

 

 

Key Factors Influencing Detection:

 

  • Hair Growth Variability: Hair growth averages around 1cm per month, but this can fluctuate between 0.7cm and 1.5cm. Such variations can complicate the timeline estimation for substance use, potentially mixing recently grown, clean hair with older substance-infused hair strands.

 

  • Metabolite Integration Period: Typically, it takes about 8-14 days for substances and their metabolites to become detectable in hair after consumption, awaiting the metabolites’ incorporation into the hair shaft and the hair’s emergence from the scalp.

 

  • Dormancy in Hair Growth: A significant portion of hair, around 15%-17%, may enter a dormant phase, halting growth temporarily. This dormancy can lead substance-infused hair to blend with the overall sample, particularly if the sample is taken from areas with a high concentration of dormant hair, like body hair.

 

  • Sensitivity of Testing Methods: The ELISA method offers a rapid, albeit limited, screening that might overlook low-level or recent use, posing a risk for false negatives or positives. LCMS (Liquid Chromatography-Mass Spectrometry), however, is recognised as the pinnacle of hair testing for its comprehensive detection capabilities and high sensitivity, providing more conclusive results.

 

  • Impact of Hair Colour: The melanin in darker hair can bind more readily to drug metabolites than in lighter hair, slightly influencing the sensitivity of detection based on hair colour.

 

Practical Considerations: Opting for a 3cm hair test via LCMS after 4 months of abstinence may not guarantee a negative result, particularly for habitual users. The chosen hair segment typically reflects the last 3 months of growth, but factors like growth rate variability and the 8-14 day period for subcutaneous hair emergence can alter this timeframe.

 

 

Laboratory Selection: Our laboratory utilises LCMS technology with specified cut-off levels to ensure the utmost precision. It’s advisable to evaluate different laboratories based on their testing methodologies (ELISA vs. LCMS) and cut-off points, as higher thresholds may lead to negative results despite the presence of substances, a critical consideration in legal contexts.

 

 

In essence, the detection of substances in hair samples post-abstinence is influenced by a myriad of factors. An informed approach to test selection, an understanding of hair growth dynamics, and the physical attributes of hair are paramount in accurately interpreting test outcomes.

Our hair testing service offers precise detection across a diverse array of substances, adeptly distinguishing between legal medications like dexamphetamine for ADHD and illicit drugs such as MDMA and methamphetamine. 

 

We excel in differentiating substances within the same category, ensuring clear identification between prescribed ADHD medications and similar illegal amphetamines, as well as between various opioids, such as the therapeutic methadone and illicit heroin, by analysing their unique metabolic markers.

 

We’re also attentive to how certain prescriptions, especially steroids prescribed for conditions ranging from anaemia to skin disorders, could influence test results. Our approach includes specialised steroid analysis to maintain the integrity and accuracy of our findings.

Circumventing a hair drug test presents significant difficulties as the metabolites from substances consumed are integrated into the very fabric of the hair which is why it’s a clear favourite for judicial proceedings. For a deeper understanding, please Click Here.

Hair testing distinguishes itself in substance detection by offering an extensive look back at drug, alcohol, and steroid use, spanning several months.

 

This capability is especially beneficial in legal settings where pinpointing substance users with precision is of paramount importance. Hair analysis effectively counters the issue of test evasion through brief periods of abstinence, providing a more thorough and dependable evaluation compared to other testing methods.

 

 

Urine Drug Testing: Urine tests have a narrower window of detection, typically capturing substance use within 1-7 days. Drugs like cocaine, methamphetamine, opiates, and PCP are metabolised quickly and may not be detectable in urine after 72 hours from the last use. Despite its promptness, urine testing’s short-term scope offers a limited view of an individual’s substance use history.

 

 

Saliva Drug Testing: Saliva tests further restrict the detection timeframe, generally identifying drug presence within 48 hours of use. This method’s appeal lies in its non-invasive nature and swift results, yet it’s constrained by a limited detection period.

 

 

Long-Term Advantages of Hair Testing: Although initially more expensive, hair testing’s value is evident over time, considering:

 

  • Reduced Frequency of Testing: With hair tests covering up to 3 months per 3cm sample—and potentially more for longer samples—fewer tests are necessary over time. This reduces the costs and logistical challenges associated with the more frequent testing needed for urine analysis.

 

  • Economic and Time Efficiency: The repeated scheduling and attending of urine test appointments can accumulate hidden costs, including lost work hours and travel expenses. Hair testing proves more cost-effective and less disruptive.

 

  • Depth of Detection: Hair testing’s prolonged detection window offers a detailed chronicle of substance use, crucial for contexts that demand an understanding of long-term usage patterns.

 

  • Simplicity and Security of Collection: Hair samples are collected easily and are less prone to the tampering risks seen in urine testing, ensuring sample integrity and test accuracy.

 

  • Precision and Consistency: Known for its high level of accuracy, hair testing lessens the likelihood of needing re-tests due to inconclusive outcomes or concerns of sample tampering, commonly associated with urine or saliva tests.

 

Saliva Testing Considerations: The reliability of saliva testing can be influenced by recent food and drink intake, due to:

 

  • pH Level Changes: Some foods and drinks can alter the pH balance of saliva, affecting drug solubility and stability, which may impact test accuracy.

 

  • Cross-Reactivity: Certain foods, like those containing hemp seeds, may cause false positives by mimicking drug compounds.

 

  • Sample Contamination: Consuming strongly coloured or flavoured items just before testing can contaminate the saliva sample, potentially affecting the detection process.

 

  • Sample Dilution: Drinking excessive fluids before the test can dilute the saliva, lowering drug concentrations below detectable levels and increasing the risk of false negatives.

 

To minimise these risks, it’s advised to avoid eating, drinking, and smoking for at least 10 minutes before saliva testing to ensure a clean sample.

 

 

In summary, hair testing’s comprehensive approach to monitoring substance use, combined with its high accuracy and reduced need for repeat testing, solidifies its utility, especially in judicial and custodial settings where detailed long-term insights are essential.

FAQ's Specific to Alcohol Testing

In the realm of EtG (alcohol) testing, a crucial distinction must be made regarding the optimal hair sample length. 

 

The Society of Hair Testing (SoHT) specifically advises that the most accurate and reliable EtG analyses are conducted on hair segments ranging from 3 to 6 cm. This guideline is tailored to EtG testing and does not apply to the testing for Drugs of Abuse (DOA) or steroids.

 

The emphasis on this particular length range stems from the established reliability of EtG analysis within these parameters. When hair samples are shorter than 3 cm, the foundation for interpreting EtG analysis results may be compromised. This is due to the scientific consensus and international guidelines, which advocate for analysing hair within the 3 to 6 cm range for sound reasons.

 

While obtaining accurate results from shorter hair samples is technically possible, the interpretation of such results faces significant challenges. The absence of standardised guidelines for analysing shorter hair samples makes it difficult to draw reliable conclusions from the findings.

 

Therefore, although conducting EtG testing on hair samples as brief as 1 cm is feasible, it is essential to approach such cases with caution. Awareness of the potential interpretative challenges associated with testing hair segments shorter than 3 cm for EtG is crucial. When considering EtG testing on shorter hair samples, it may be wise to exercise prudence and consider the potential need for legal advice due to the interpretive limitations that could emerge.

To detect alcohol consumption through hair testing, we measure ethyl glucuronide (EtG), a direct metabolite of ethanol, rather than alcohol itself. 

 

EtG in hair serves as a reliable indicator of alcohol intake and is a widely recognised method in the field. EtG integrates into the hair through diffusion from the bloodstream and from sweat, embedding itself along the entire length of the hair shaft.

 

The interpretation of EtG levels in head hair is as follows:

  • A concentration of 30 picograms per milligram (pg/mg) or higher typically indicates chronic excessive drinking.
  • Conversely, a concentration of 5 pg/mg or lower is generally consistent with abstinence.

 

To summarise the EtG level interpretations:

  • Levels below 5 pg/mg suggest abstinence from alcohol.
  • Levels between 5 to 29 pg/mg imply repeated alcohol consumption.
  • Levels of 30 pg/mg or above strongly suggest chronic excessive alcohol consumption.

 

The standard practice involves testing a 3cm segment of head hair, which provides a retrospective insight into alcohol consumption over the preceding three months. It’s important to note that the actual timeframe may vary slightly due to individual differences in hair growth rates. The cost of testing is typically based on each 3cm segment of hair analysed.

If your test results indicate the presence of alcohol, it’s important to understand what these levels signify.

 

According to the Society of Hair Testing (SoHT), which establishes global standards for drug and alcohol testing, chronic excessive alcohol consumption is defined as consuming an average of 60g or more of pure ethanol daily over several months. To put this into perspective, a standard drink contains approximately 10g of alcohol.

 

In head hair, an Ethyl Glucuronide (EtG) level of 30 picograms per milligram (pg/mg) or higher is indicative of consuming six or more standard drinks per day over an extended period. For a more detailed explanation of the SoHT’s guidelines regarding alcohol markers in hair, you can visit their website at SoHT Consensus.

 

The SoHT provides specific benchmarks for interpreting EtG levels in hair:

  • EtG levels below 5 pg/mg suggest abstinence from alcohol.
  • EtG levels between 5 to 29 pg/mg strongly indicate repeated alcohol consumption.
  • EtG levels of 30 pg/mg or above are indicative of chronic excessive alcohol consumption.

 

Our forensic laboratory adheres to the international hair alcohol reporting standards established by the SoHT, ensuring that our analyses are both accurate and reliable.

The test does not differentiate between “binge” drinking patterns and consistent excessive alcohol consumption.

It provides an average indication of alcohol intake over the duration being tested, typically a 3 to 6-month period.

 

The presence of alcohol markers like EtG (ethyl glucuronide) in hair only reveals the cumulative levels detected, without specifying the frequency of alcohol deposition into the hair matrix.

Therefore, the levels found in a person who engages in frequent binge drinking could be comparable to those of an individual who consistently consumes alcohol.

 

 

While the test can quantify the amount of alcohol markers present in the hair over a selected time frame, it cannot detail the regularity of alcohol consumption. The standard testing window is usually a retrospective look at the past 3 months.

The concept of “social drinking” varies significantly among individuals, leading to differing opinions on the matter. 

 

The Society of Hair Testing (SoHT), a leading authority in drug and alcohol testing, categorises chronic excessive alcohol consumption as the intake of 60 grams of pure ethanol per day over an extended period. Given that one standard drink typically contains 10 grams of alcohol, this definition aligns with consuming six or more standard drinks daily over several months.

 

In hair alcohol testing, an Ethyl Glucuronide (EtG) concentration of 30 picograms per milligram (pg/mg) or higher in a hair sample (spanning 3 cm to 6 cm) is indicative of chronic excessive alcohol consumption. Conversely, EtG levels of 5 pg/mg or lower in a similar hair length do not dispute claims of abstinence.

 

While the test results will quantify the EtG levels in the hair sample, they do not provide legal interpretations of what these levels signify. For those requiring detailed analysis and interpretation of results in legal contexts, our independent forensic toxicologist, Dr. Michael Robertson, offers expert services for an additional fee. This service is particularly valuable for individuals seeking further understanding beyond the information provided in our FAQ section.

Determining if a single night of drinking will result in a positive EtG hair test is complex, largely because the correlation between the quantity of alcohol consumed and the resultant EtG levels in hair varies significantly among individuals. 

 

An EtG concentration near 5 pg/mg could suggest occasional or social drinking over the period reflected by the hair sample.

 

Various factors, including the type and amount of alcohol consumed, affect EtG levels. For instance, the impact of consuming wine may differ from that of vodka, and the effect of two drinks can be quite different from ten. Since the test averages EtG concentrations across the sampled hair length, a segment with a high EtG concentration from a single night of heavy drinking could potentially yield a positive result.

 

The Society of Hair Testing (SoHT), which establishes international guidelines for hair drug and alcohol testing, delineates the following EtG level interpretations:

  • EtG levels below 5 pg/mg suggest abstinence.
  • EtG levels between 5 to 29 pg/mg imply occasional or repeated alcohol use.
  • EtG levels of 30 pg/mg or above typically indicate chronic excessive alcohol consumption, equating to six or more standard drinks per day over several months.

 

For further details on SoHT’s alcohol marker guidelines in hair, you can visit their website at SoHT Consensus.

 

Our forensic laboratory adheres to the SoHT’s international standards for hair alcohol testing, ensuring our practices align with globally recognised benchmarks.

Determining the exact number of alcoholic drinks consumed within a specific timeframe using a hair alcohol test is complex due to various factors that influence EtG (ethyl glucuronide, an alcohol metabolite) levels in hair.

 

The relationship between the quantity of alcohol consumed and the resultant EtG concentration isn’t linear or uniform across individuals.

 

An EtG level around 5 pg/mg may suggest occasional or social alcohol use over the period represented by the hair sample. This level could also reflect alternating periods of higher and lower alcohol consumption, given the averaged nature of the result over the length of hair tested.

 

Conversely, an EtG level near 30 pg/mg may indicate more significant alcohol intake, potentially aligning with an average of up to six standard drinks per day over the sample period. This higher range could also encompass fluctuations in drinking patterns, including intervals of heavy and minimal alcohol use.

 

Interpreting EtG results should ideally be done in conjunction with other indicators of alcohol consumption, such as eyewitness accounts, financial records, and other relevant evidence.

 

The Society of Hair Testing (SoHT) provides benchmarks for interpreting EtG levels in hair:

  • EtG levels below 5 pg/mg suggest abstinence.
  • EtG levels between 5 to 29 pg/mg indicate repeated alcohol use.
  • EtG levels of 30 pg/mg or higher are indicative of chronic excessive alcohol consumption.

 

According to SoHT, chronic excessive consumption is defined as the intake of 60 grams or more of pure ethanol daily over several months. With a standard drink containing approximately 10 grams of alcohol, an EtG level exceeding 30 pg/mg in head hair aligns with consuming six or more standard drinks per day over this duration. For further details, the SoHT’s guidelines on alcohol markers in hair are available at SoHT Consensus.

 

Our forensic laboratory adheres to the international hair alcohol reporting standards as defined by the SoHT, ensuring our testing methodologies and interpretations are in line with globally recognized guidelines.

The Society of Hair Testing (SoHT) no longer includes Fatty Acid Ethyl Esters (FAEEs) in their Consensus on Alcohol Markers as of the 2019 revision. 

 

This decision followed the earlier removal of FAEEs from their proficiency testing program, attributed to the “lack of uniformity surrounding the analysis and interpretation of FAEE results.” The inconsistencies in analysing and interpreting FAEE data led to the SoHT’s decision to exclude these markers from their standardised alcohol testing guidelines.

Carbohydrate-deficient transferrin (CDT) is typically not tested in hair as it is a blood biomarker.

 

Testing CDT in hair isn’t feasible because the biomarker is specific to the blood and does not deposit into hair in a way that can be measured reliably.

 

Hair testing for alcohol consumption primarily utilises direct ethanol metabolite ethyl glucuronide (EtG) which integrates into hair and can provide a historical record of alcohol use.

 

The preference for EtG over CDT in determining chronic alcohol consumption, especially in legal contexts, is based on several factors related to the markers’ sensitivity, specificity, and detection windows.

 

Sensitivity and Specificity:

 

EtG is a direct metabolite of alcohol, highly specific and sensitive to alcohol ingestion. It effectively detects even low levels of alcohol consumption and can identify relapses.

 

CDT, detected in serum, measures changes in transferrin glycosylation due to heavy alcohol use over time.

It is less sensitive than EtG, particularly for low or moderate alcohol intake and prone to false positives in cases of liver disease, genetic variations and the individual’s iron status. 

 

 

Detection Window:

 

EtG can be detected in hair, providing a historical record of alcohol intake over several months, which is crucial for legal cases needing to establish a pattern of consumption.

 

CDT is not tested in hair as it is a blood-specific marker and does not deposit into hair. Its levels are indicative of heavy drinking but normalise more quickly than changes detectable by EtG.

 

 

Reliability and Legal Use:

 

EtG is favoured in legal settings due to its accuracy and extended detection period. It is reliable when performed using standardised protocols, though care must be taken to consider potential external sources of alcohol that could lead to false positives.

 

CDT, while useful for detecting prolonged heavy drinking via blood tests, lacks the capability to be tested in hair and does not provide the long-term consumption history that hair tests for EtG offer.

 

 

In summary, EtG is preferred over CDT for hair testing in legal contexts because of its greater sensitivity, specific detection of alcohol, and the ability to monitor alcohol consumption over an extended period.

 

This makes EtG a more effective tool for use in court, whereas CDT’s use remains confined to blood tests where it serves to indicate recent heavy alcohol use.

 

The direct determination of alcohol (ethanol) itself in hair is not possible due to its volatility and its potential absorption from external sources. Instead, the alcohol metabolite ethyl glucuronide (EtG) is measured in hair as a direct marker of alcohol consumption.
 
EtG is produced in the liver after the consumption of alcohol. This means the metabolite is tested not alcohol directly (“metabolite” is the outcome when the body breaks down a substance eg alcohol).
 
Therefore the use of shampoo containing alcohol should not result in a positive test, as the test is not measuring alcohol directly but its metabolite (EtG), as the product is not being ingested. However, we would advise that the hair donor declares the use of the shampoo at the time of hair collection.
While it’s theoretically conceivable that alcohol metabolites could transfer from a mother to her baby through breast milk, there is currently no conclusive research to support this pathway for alcohol detection in infants. Therefore, as of now, testing a baby’s hair for alcohol ingestion via breast milk is not a validated method. 
 
Due to these uncertainties, it’s more practical and reliable to test the mother for alcohol consumption if there are concerns about alcohol exposure to the infant.

FAQ's Specific to Steroid Testing

We offer one of the greatest steroid detection capacity in Australia testing over 40 known steroids and their esters with a high degree of sensitivity using Mass Spectrometry (5 – 20 pg/mg from a 20 mg hair sample).

 

Results are admissible for medico/legal proceedings. For a full list of steroids tested Click Here

Determining whether a single dose of steroids can be detected involves numerous variables, making a definitive answer challenging. These variables include:

  • The amount of steroid consumed.
  • The concentration and purity of the steroid.
  • The presence of any additives in the steroid formulation.
  • The frequency of steroid use, whether it’s a single instance or chronic usage.
  • Previous steroid exposures.
  • Individual factors like metabolism rate, body weight, and renal function.

 

Given these factors, it’s difficult to predict with certainty if a single dose will be detectable. However, the choice of detection or testing methods plays a pivotal role in accurately identifying steroid ingestion.

 

In the context of judicial proceedings, Liquid Chromatography-Mass Spectrometry (LCMS) is often considered the gold standard for hair steroid testing due to its precision. Our clinic exclusively employs LCMS for this reason.

 

 

Additionally, the fat solubility of anabolic-androgenic steroids (AAS) means that these substances can integrate into the body’s fat stores, potentially allowing their metabolites to remain detectable for extended periods. For example, steroids like Deca Durabolin may be identifiable for over a year, attributed to their propensity for fat storage.

The duration for which steroids can be detected in the body is influenced by a myriad of factors, making steroid detection a notably intricate matter compared to many other drug substances. Here are the key elements that impact steroid detectability:

 

  • Type of Anabolic Androgenic Steroids (AAS): The metabolism rates of AAS drugs vary widely; some are processed and leave the body within days, whereas others can linger for months, depending on their metabolic breakdown ease.
 
  • Designer vs. Standard Steroids: Some athletes may choose designer AAS, engineered to evade detection more effectively. In certain instances, these may be completely undetectable, making the concept of a detection window void.
 
  • Detection Methods: The detectability of specific steroid compounds differs significantly across various drug test modalities. While some steroids can be identified across all common testing platforms, others may only be detectable through particular methods, like hair testsing thus influencing the potential detection timeframe.
 
  • Dosage and Duration of Use: The amount and length of steroid use significantly affect the concentration of AAS in the body, thereby influencing the detectability in tests.
 
  • Mode of Administration: The body metabolises and excretes oral steroids faster than injectable forms, which means the detectability window varies with the administration route.
 
  • Fat Solubility: AAS drugs are lipophilic, tending to accumulate in the body’s fat reserves. This attribute allows the fat to harbour metabolites for protracted periods, with certain steroids like Deca Durabolin detectable for over a year due to their affinity for fat storage.
 

Navigating steroid drug tests successfully entails meticulous planning and in-depth research into the substances in question. The layered complexity of these factors heightens the risk of unintentionally failing an essential drug screen.

In urine testing, the focus is on identifying testosterone metabolites, whereas hair analysis not only detects testosterone but also, crucially, the intact testosterone esters often used in testosterone replacement therapy (TRT).


When an individual is prescribed TRT, the treatment typically involves one or more specific testosterone esters, such as Testosterone enanthate. The detected steroid esters in the hair sample should correspond to those prescribed. Instances have been noted where individuals have augmented their prescribed TRT regimen with additional substances.


It’s important to note that while this test quantitatively measures testosterone levels, it provides only a qualitative assessment for other anabolic substances, meaning it can confirm the presence or absence of testosterone esters without indicating their concentration.

Anabolic steroids can lead to a range of side effects, varying in severity:

 

  • Emotional and behavioural changes, including mood swings and heightened aggression.
  • Reproductive issues, such as testicular shrinkage and reduced sperm count in men.
  • Gynecomastia, or the development of enlarged breast tissue in men.
  • Fluid retention, leading to swelling in various parts of the body.
  • Fatigue and a general feeling of tiredness.
  • Depression, which can range from mild to severe.
  • Discomfort or pain during urination.
  • Clitoral enlargement in women.
  • An increase in red blood cell count, which can have multiple effects on health.
  • A decrease in high-density lipoprotein (HDL) or “good” cholesterol.
  • Elevated blood pressure, contributing to cardiovascular strain.
  • Heightened risk of cardiac events, such as heart attacks.
  • Liver issues, including an increased risk of liver disease and liver cancer, as the liver works to detoxify the body.
  • Changes in hair growth patterns, including facial hair growth in women and baldness in men.
  • Sleep disturbances, including insomnia.
  • Reduced libido or sex drive.
  • Increased likelihood of osteoporosis, leading to weakened bones.
  • Higher chance of tendon ruptures, which can result from compromised tissue strength.
  • Skin conditions, such as acne.
  • A strong desire or craving for steroids, which can lead to dependency.

If you’re seeking a basic overview to identify regular or chronic usage of illicit substances, the following published levels are generally recognised indicators:

 

  • Cannabis (THC & CBD): Levels above 50 pg/mg suggest regular use.
  • MDMA (Ecstasy)/MDA: Concentrations over 200 pg/mg are indicative.
  • Methamphetamine: A level exceeding 200 pg/mg points to regular use.
  • Amphetamine: Similarly, more than 200 pg/mg signals regular consumption.
  • Cocaine: Levels above 500 pg/mg denote regular use.
  • Ketamine: A concentration greater than 200 pg/mg suggests habitual use.
  • Heroin Metabolite (6-Monoacetylmorphine): Over 200 pg/mg indicates regular usage.
  • LSD: Any detectable level is noteworthy due to its potency.

 

For alcohol analysis through EtG levels in hair:

  • <5 pg/mg: Consistent with abstinence.
  • 5 to 29 pg/mg: Strongly indicates repeated consumption.
  • >30 pg/mg: Points to chronic excessive drinking.

 

Interpretation should be approached with caution, considering factors like metabolism, hair pigmentation, and cosmetic treatments, which can all influence drug/alcohol levels in hair. Treat this as a general reference, not a precise measurement.
