Specimen Collection

Home / / EtG Hair Follicle Alcohol Test

The collector obtains a 100 milligram sample of hair (90 to 120 strands) cut at the scalp. The collector secures the hair sample in foil and completes chain-of-custody documentation in preparation for shipment to the testing laboratory. Since hair samples are obtained in full view of the collector, the process minimizes the likelihood of sample adulteration or specimen substitution. Detect Lab offers hair specimen collections in many of our specimen collection labs located throughout the United States. Our extensive network offers your employees convenient access to a Detect Lab collection site.

How does hair alcohol testing work?

The body produces EtG and EtS when alcohol is present in the bloodstream and the EtG markers that are absorbed into the hair structure is what is analyzed from a sample of hair.

Human hair is said to grow at the rate of one half inch or 1.5 cm per month. EtG Hair Follicle Test for Alcohol use requires about 120 strands of hair.

EtG Hair Alcohol Testing shows extended history of alcohol use and is used for:

  • Custody Cases
  • Employment Screening
  • Proves Eligibility for liver transplant
  • Probation and DWI Offenders
  • Safety Sensitive Industries
  • Return to Work Programs
  • Wellness Programs
  • Rehab Facilities & Healthcare Facilities
  • Family Courts
  • Law Enforcement Agencies
  • Schools & Parents
  • Last Chance Agreements
  • Adoptions

ETG test checks for Ethyl Glucuronide – one of the alcohol metabolites, which stays in the body longer than the rest. As we know, hair traps the metabolites forever while urine gets clean within 80 hours. Why is the hair alcohol ETG test is preferred to urine ETG test?

  • Depending on hair length, a hair sample can provide a history of alcohol consumption for the last several months.
  • This non-invasive test can give a full description about a person’s drinking pattern and distinguish how long a person was staying sober for. It can determine if a person was a heavy drinker, a social drinker or just had a couple drinks in the past several months.
  • ETG metabolites remain in the hair for as long as the hair stays on the body. Dyeing, bleaching or having hair permed, does not affect the outcome of the hair since ETG metabolites cannot be removed by those products.
  • Hair tests are generally more expensive, but one hair sample can be used not only for ETG test, but also for other types – standard drugs of abuse.
  • Hair tests for alcohol will not work on body hair and therefore only work with scalp hair that needs to be at least an inch in length.
  • Although ETG hair test is considered to be quite accurate.

Testing Process

Detect Lab Corp offers initial screening tests performed by enzyme-linked immunosorbent assay (ELISA) with confirmation of presumptive positive screens by gas chromatography/tandem mass spectrometry (GC/MS/MS) or liquid chromatography/tandem mass spectrometry (LC/MS/MS). Results for specimens that screen negative for all drugs are generally available within 48-72 hours after specimens are received at the laboratory. Results for confirmation testing of presumptive positive screens are usually available within an additional 72 hours.

Hair Drugs of Abuse Testing Frequently Asked Questions

Q: What is hair drug testing?
Drug and drug metabolite(s) are incorporated into the hair matrix from the bloodstream following drug use. Hair drug testing detects drugs that are embedded in the hair.1

Q: How much hair is needed for a hair drug test?
A hair drug test with initial screen and confirmation requires 100 milligrams of hair (90 to 120 strands).

Q: What time period does a hair drug test cover?

Hair growth rates vary; typically, head hair grows at an average of one-half inch per month. Therefore, a 1.5 inch hair sample detects drug use up to 90 days prior to testing.1

Q: How does the drug detection window for hair compare to urine and oral fluid?
Drug detection times vary depending on the dose, sensitivity of the testing method used, preparation and route of administration, duration of use (acute or chronic), the matrix that is analyzed, the molecule or metabolite that is looked for, the pH and concentration of the matrix (urine, oral fluid), and variations in metabolic and renal clearance.2 In general, the detection time is longest in hair, followed by urine and oral fluid.2 Drugs in hair may be detectable for approximately 90 days, whereas drugs in urine are generally detectable for one to seven days or longer in chronic users and in oral fluid from five to 48 hours.2

Q: How soon after use can a drug be detected in hair?
Drug (and/or metabolite) can be detected approximately seven to 10 days from the time of drug use. This is the time in which the affected hair grows from the follicle to emerge above the scalp.

Q: How can tests be run on people with little or no hair?
Hair may be collected from several head locations and combined to obtain the required amount of hair. If no head hair is collectable, an employer may choose to use oral fluid or urine testing to detect drug use.

Q: Can hair collected from a brush be used?
No, a hair sample must be collected using proper chain-of-custody protocol and collection techniques. The test subject must verify the authenticity of the sample at the time of collection.

Q: When testing for drugs, what are the differences between hair testing cut-off levels and urine testing cut-off levels?
Urine cut-off levels are expressed in nanograms per milliliter (ng/mL) or as a weight of drug per unit volume of urine. Hair cut-off levels are expressed in picograms per milligram (pg/mg) or as a weight of drug per unit weight of hair.

Q: How does the laboratory address external exposure to certain drugs like marijuana or crack (cocaine) smoke?
While washing the hair sample may remove some of the contamination, ultimately external exposure can be differentiated from actual use because of the presence of the drug metabolite, which is not present when environmental contamination is the source of the drug.
