Hair follicle drug testing is a method for determining whether an applicant or employee uses illegal or prescription drugs. It can also determine whether a person was under the influence of narcotics at the time of an accident or incident. A hair follicle test is conducted by collecting a hair sample from the scalp and submitting it to a laboratory for analysis. It can detect numerous substances and drug metabolites.

The most prevalent sample collected for a hair follicle drug test is head hair, but body hair can also be taken. These samples are typically taken as close to the scalp as feasible and must be at least half an inch long.

A hair follicle test is more accurate than a urine test because drug metabolites persist in the hair for weeks, months, or even years after drug use.

Employers frequently request a hair follicle drug test, particularly for positions that require physical activity. It can also be used as part of a random drug testing program for employers.

A hair follicle drug test can detect various substances, including prescription medications and illegal narcotics like marijuana. It can also detect drug use within the past 90 days, making it ideal for workplace drug testing. It is also frequently administered by court order.

Yes, it is a fact that the hair on your head grows quicker than the hair on the rest of your body. The hair follicle is quite adept at detecting drug residue in the human body, which is one of the reasons why hair samples are collected from various body parts. The hair follicle is one of the body's more delicate organs, so it is prudent to always keep a close watch on it. This organ contains the main cranial nerves and endocrine glands in charge of hormone production, cellular repair and growth, and reproductive functions. A network of microscopic blood vessels known as ducts regulate the abovementioned functions.

Drug metabolites can enter hair follicles through sweat or cigarette smoke exposure. A hair follicle drug test may detect these metabolites if they are present in your hair.

Due to the extended detection time, this method may be less precise than urine testing. Moreover, several factors can make it challenging to interpret the results of a hair follicle drug test.

Before being tested, hair samples are typically cleansed to remove environmental contaminants that could alter the test result. The sample is then analyzed with ELISA or GC-MS to identify the presence of drugs or drug metabolites.

Some employers use hair follicle drug tests to determine whether or not an employee has engaged in illegal drug use. In addition, they are used to monitor employees who may have been involved in a workplace accident or drug-related incident.

A hair follicle test identifies a drug metabolite produced by the body during the breakdown of a substance. If the drug metabolite is found, the individual has probably used drugs.

The results may be inconclusive if a hair sample is tainted or something goes awry during testing. In such instances, the laboratory will request a second sample.

A drug test on hair follicles can detect narcotics for up to 90 days, which is longer than urine tests. After submitting a hair sample for analysis, results are typically available within two to three days.
