At Quick Test Health Services, we often get questions about hair drug testing, especially when it comes to testing for alcohol consumption using ETG. In this blog, we'll break down what a hair drug test with ETG is, how it works, why it's used, and who typically benefits from this type of test.
What is a Hair Drug Test with ETG?
A hair drug test with ETG is a method used to detect the presence of a specific biomarker called Ethyl Glucuronide (ETG) in hair. ETG is a direct metabolite of ethanol, which is the type of alcohol found in alcoholic beverages. When a person consumes alcohol, their body breaks it down, and ETG forms as a byproduct. This byproduct can remain in the body and can be detected through various testing methods, including hair.
Hair drug testing is different from other forms of testing, like urine or blood tests, because it can detect substance use over a much longer period. It’s often used to evaluate whether someone has been consistently using drugs or alcohol over several months, rather than just determining recent use.
How is the Hair Sample Collected?
Collecting a hair sample for a drug test is simple, quick, and painless. A small section of hair, typically from the crown of the head, is cut close to the scalp. The sample is usually about 1.5 inches long, which represents roughly three months of hair growth. The reason for cutting close to the scalp is that this is where the most recent growth has occurred, giving an accurate reflection of recent exposure to drugs or alcohol.
In cases where head hair isn't available, body hair (such as from the arms, legs, or chest) can be used.
Why is Hair Drug Testing with ETG Performed?
Hair drug testing with ETG is often performed to monitor alcohol use over an extended period. Since ETG remains detectable in hair for a much longer time compared to urine or blood, this method is ideal for evaluating long-term patterns of alcohol consumption.
This type of test is commonly used in several situations, including:
Legal Matters: Courts may request ETG hair testing in cases involving child custody, probation, or DUI offenses to determine if someone has been abstaining from alcohol.
Employment Screenings: Some employers may require hair drug testing to ensure that their employees are adhering to company policies regarding substance use.
Rehabilitation and Recovery Monitoring: For individuals in recovery from alcohol addiction, hair testing is a way to track sobriety over time.
Family or Personal Requests: In some cases, family members or individuals themselves may want to test for alcohol use to gain clarity or resolve personal concerns.
How Long Does ETG Stay in Hair?
One of the biggest benefits of hair testing is its long detection window. ETG can be detected in hair for up to 90 days or even longer, depending on the length of the hair sample. This makes it a valuable tool for anyone needing to monitor alcohol use over a long period. Unlike urine tests, which only detect recent alcohol consumption (within 1-3 days), hair tests provide a much clearer picture of alcohol use over weeks or months.
Who Typically Uses Hair Drug Testing with ETG?
Hair drug testing with ETG is typically used by a wide range of organizations and individuals, including:
Courts and Legal Authorities: As mentioned earlier, courts may request this test in cases where long-term alcohol abstinence is a key factor, such as in custody disputes or DUI offenses.
Employers: Some companies, particularly those with strict drug and alcohol policies, may request hair testing for both pre-employment screenings and ongoing employee evaluations.
Rehabilitation Programs: Addiction treatment centers and therapists may use hair testing to monitor a patient’s recovery progress and ensure they are remaining alcohol-free.
Individuals Seeking Proof of Sobriety: People in recovery or those looking to demonstrate their sobriety for personal reasons often use hair drug testing with ETG.
