EtG (Ethyl Glucuronide) Alcohol Test (Alcohol Metabolite) (Hair)

The EtG (Ethyl Glucuronide) Alcohol Test (Alcohol Metabolite) (Hair) test will identify the presence or absence of EtG in a hair sample.  As a laboratory-based test, this panel includes a routine screen for the presence of EtG, as well as any necessary confirmation testing.  

Ethyl glucuronide is a metabolite of alcohol that can be used to detect alcohol use in people for a longer period of time than direct tests for alcohol.  EtG is deposited in hair as it grows through exposure to blood, sweat, and skin oils.  On average, EtG will become detectable in head hair beginning at 7 days after heavy alcohol use and extending as far back as 90 days if the hair sample collected is at least 1.5 inches in length.  A confirmed positive result for EtG is considered evidence of heavy alcohol use in that time period.  Note that body hair does not grow at the same rate as head hair, therefore the window of detection is less precise.  Results of this test cannot be traced back to a person’s blood alcohol concentration at a specific time in the past.  Infrequent use of alcohol also may not be detectable using this test.

This test requires a head or body hair sample that can be collected at the Any Lab Test Now store location of your choice.

FAQs

WHY DO I NEED THIS TEST?

The EtG (Ethyl Glucuronide) Alcohol Test (Alcohol Metabolite) (Hair) test is recommended for consumers seeking a drug test for personal knowledge, legal, or employment-related purposes.  It is also recommended for consumers who are concerned about suspected long-term abuse or misuse of alcohol by a friend or family member, including teenagers.

For Law Enforcement Agencies or Substance Abuse Monitoring Programs:

The EtG (Ethyl Glucuronide) Alcohol Test (Alcohol Metabolite) (Hair) is recommended for agencies or programs responsible for monitoring individuals who are required to abstain from drug use.

WHAT ARE THE ADVANTAGES OF HAIR DRUG TESTING?

Hair drug testing is non-invasive, less subject to specimen tampering, and provides a wider window of detection compared to a standard urine drug test.  It is also the best method for detecting patterns of chronic alcohol use that may be missed by a urine drug test if the timing of the test doesn’t align with recent use.  

WHAT DO I NEED TO DO TO PREPARE?

We ask only that hair be clean and free of excessive styling products.  Hair that is visibly damaged by repeated chemical processing may be rejected by the laboratory and cannot be collected for testing. 

CAN MY RESULTS BE AFFECTED BY ENVIRONMENTAL CONTAMINATION?

No. Unless otherwise requested, hair samples are always washed by the laboratory to remove external contaminants before testing.

IS IT SAFE TO TAKE THIS TEST IF I AM PREGNANT?

Yes.

DO I NEED TO MAKE AN APPOINTMENT?

No.  You can walk in for same-day testing.  We make it easy by offering work-friendly store hours.

HOW LONG WILL IT TAKE TO GET MY RESULTS?

Most negative drug test results are available within 24-48 hours.  Allow additional time for confirmation testing to be completed if necessary.

WHO HAS ACCESS TO MY RESULTS?
