Alcohol (EtG) Hair Testing

Hair alcohol testing measuring ethyl glucuronide (EtG) to assess consumption over time. A minimum 3-month window is recommended for reliable results — shorter samples can be tested but give a less dependable assessment of drinking patterns.

Measures EtG, a validated biomarker of actual consumption
Distinguishes abstinence from social and chronic drinking
Read against published international thresholds
Widely used in family law, child protection and abstinence programs
Analysed in Australia, never sent overseas

International guidelines recommend a minimum of 3 cm of hair for EtG analysis. Those same thresholds are set for segments of 3–6 cm, so if you need 9 or 12 months, call (03) 9380 5434 first — how a longer alcohol sample is reported changes what the result can be used to say.

Check your hair length first. Measured from the scalp along the strand, 1 cm is about a month — so 6 months needs 6 cm and 12 months needs 12 cm. If your hair is shorter, the result covers less: the length decides the period, not the window you pay for. Unsure? Call (03) 9380 5434 before ordering.

If your test relates to a legal matter, confirm the required timeframe with your solicitor first.
