If you are looking for a reliable and accurate way to measure if someone has been drinking alcohol, then a hair follicle test may be the answer. Hair follicle testing has become increasingly popular in recent years as a way to determine if someone has consumed alcohol in the past month or even longer. In this article, we will explore the advantages and disadvantages of this type of testing and discuss the science behind it. We will also offer some tips for those who may be considering hair follicle testing for themselves or for someone else. So, let’s get started– does hair follicle test for alcohol?

Does Hair Follicle Test for Alcohol?

What is Hair Follicle Testing?

Hair follicle testing is a method of drug testing that is used to detect the presence of drugs and alcohol in a person’s system. The test involves collecting a small sample of hair from the scalp and testing it for traces of drugs and alcohol. Hair follicle testing is more accurate than urine and blood tests, as the hair follicles can detect traces of drugs and alcohol up to 90 days after use.

Hair follicle testing has become increasingly popular in recent years, as it is a non-invasive and reliable method of drug and alcohol testing. Hair follicle testing is commonly used in workplace drug testing, as well as in criminal justice settings such as probation or parole.

What Does Hair Follicle Testing for Alcohol Look For?

Hair follicle testing for alcohol looks for ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) in the hair follicles. EtG is an alcohol metabolite that is produced when alcohol is broken down in the body. EtG can be detected in the body for up to 80 hours after alcohol consumption. FAEEs are another type of alcohol metabolite that can be detected in the hair follicles up to 90 days after alcohol consumption.

Hair follicle testing is considered to be one of the most reliable methods of testing for alcohol, as it can detect alcohol use up to three months after the most recent consumption. Hair follicle testing can also detect alcohol use at lower concentrations than other methods of testing.

How is Hair Follicle Testing for Alcohol Conducted?

Hair follicle testing for alcohol is conducted by collecting a sample of hair from the scalp. The sample is then sent to a laboratory for analysis. The laboratory will use a technique called gas chromatography-mass spectrometry (GC-MS) to detect the presence of EtG and FAEEs in the hair sample.

If the laboratory detects the presence of EtG or FAEEs in the hair sample, then the person has tested positive for alcohol use. It is important to note that hair follicle testing cannot determine how much alcohol was consumed, or when the alcohol was consumed.

What is the Accuracy of Hair Follicle Testing for Alcohol?

Hair follicle testing for alcohol is considered to be one of the most accurate methods of testing for alcohol. The accuracy of the test is largely dependent on the laboratory that is conducting the test, as well as the quality of the hair sample that is collected.

The accuracy of hair follicle testing for alcohol is further enhanced by the fact that it can detect alcohol use at lower concentrations than other methods of testing. This makes it more reliable than other methods of testing, as it can detect even small amounts of alcohol in the system.

What are the Limitations of Hair Follicle Testing for Alcohol?

The main limitation of hair follicle testing for alcohol is that it cannot determine how much alcohol was consumed, or when the alcohol was consumed. It is also important to note that hair follicle testing can only detect alcohol use up to 90 days after the most recent consumption.

Another limitation of hair follicle testing is that it is subject to false positives, as some medications and certain medical conditions can cause a false positive result. If a person has a false positive result, it is important for them to discuss the result with their doctor to determine the cause.

Does Hair Follicle Testing for Alcohol Require Consent?

Yes, hair follicle testing for alcohol does require the consent of the person being tested. Hair follicle testing is considered to be an invasive procedure, and as such, it is important that the person being tested is aware of the procedure and has consented to it.

In addition, the person being tested should be informed of the potential consequences of a positive result, such as disciplinary action or criminal charges. It is also important to note that hair follicle testing is usually done in a controlled environment, such as a laboratory or a workplace drug testing facility.

Are There Any Alternatives to Hair Follicle Testing for Alcohol?

Yes, there are other methods of testing for alcohol that can be used instead of hair follicle testing. These include urine tests and breathalyzer tests. Urine tests can detect alcohol up to 24 hours after consumption, while breathalyzer tests can detect alcohol up to 12 hours after consumption.

It is important to note that these alternative tests are not as reliable as hair follicle testing, as they can only detect alcohol use up to a certain period of time after consumption. In addition, these tests are subject to false positives, and as such, it is important to discuss any positive results with a doctor.
