ETG Hair Drug Test

ETG Hair Drug Test

Alcohol Testing

The EtG (Ethyl Glucuronide) Hair Drug Test is a specialized laboratory-based test designed to detect the presence of ethyl glucuronide, a metabolite of alcohol, in a hair sample. This test is effective for identifying heavy alcohol use over an extended period, providing a reliable measure of alcohol consumption beyond the capabilities of standard blood or urine tests.

  • Purpose:

    • To detect heavy alcohol use through the presence of EtG in hair.
  • What It Detects:

    • Ethyl Glucuronide (EtG), a metabolite that indicates alcohol consumption.
  • Testing Procedure:

    • A hair sample is collected, typically at least 1.5 inches in length.
    • The sample undergoes routine screening for EtG, with confirmation testing performed if necessary.
  • Detection Timeline:

    • EtG can become detectable in head hair approximately 7 days after heavy alcohol use and can be traced back as far as 90 days, depending on hair length.
    • Detection in body hair is less precise due to different growth rates.
  • Interpretation of Results:

    • A confirmed positive result for EtG suggests evidence of heavy alcohol use within the detection window.
    • Results do not correlate with blood alcohol concentration at any specific time in the past.
    • Infrequent alcohol use may not be detectable with this test.
  • Intended Use:

    • This test is specifically intended to identify heavy use of ethyl alcohol.

The EtG Hair Drug Test is a valuable tool for monitoring alcohol consumption, particularly in contexts such as rehabilitation, employment screening, or legal situations, where understanding a person’s alcohol use history is crucial.

Why would I need the ETG Hair Drug Test?
This test is recommended for several reasons: Monitoring alcohol abstinence: To verify if someone has maintained abstinence from alcohol over an extended period, often used in treatment programs or court-mandated monitoring. Professional compliance: For individuals in safety-sensitive positions (e.g., pilots, truck drivers) or professions requiring strict abstinence from alcohol. Legal proceedings: To provide evidence of alcohol consumption or abstinence in cases involving custody disputes, DUI offenses, or other legal matters. Long-term detection: To detect alcohol consumption over a long window (up to 90 days) rather than the short-term detection offered by blood or urine tests.
How do I prepare for the ETG Hair Drug Test?
Avoid using alcohol-based products: Since ETG is a metabolite of alcohol, it is important to avoid products containing alcohol (e.g., certain hair sprays, shampoos, and conditioners) for a few days before the test to prevent any potential contamination, though this is rare.
What do the results of the ETG Hair Drug Test indicate?
Negative result: This indicates that ETG was not detected in the hair sample, suggesting that there was no significant alcohol consumption during the detection period (typically up to 90 days). Positive result: Indicates that ETG was detected, showing that alcohol was consumed during the detection period. The level of ETG in the hair can sometimes provide information on the frequency and amount of alcohol consumed, but it is not a precise measurement of specific drinking levels.
