A hair follicle drug test can determine patterns of illicit drug use or prescription medication misuse over a certain period — typically 3 monthsTrusted Source for hair samples that come from a person’s head.

Testers can use hair follicle tests to check for a specific drug, or they can test a single hair sample for several different drugs or drug classes.

A hair follicle test can detect:

• Alcohol - Up to three Months
• cannabis
• amphetamines, including methamphetamine, MDMA (ecstasy), and MDEA (eve)
• cocaine
• opiates, such as heroin, codeine, and morphine
• phencyclidine (PCP)

A person may need to undergo drug testing for employment, legal, or medical purposes.

Some companies require potential employees to take a drug test as part of their application process, particularly for jobs that carry a high risk of injury. Employers may also carry out random drug testing for current employees, or they may request drug tests following serious accidents or incidents.

In the United States, drug testing laws vary from state to state. Some states prohibit employers from drug testing their employees on a random basis. In these states, an employer must provide evidence that supports their decision to test a particular employee.

Some states only allow for pre-employment using a hair follicle drug test, while other states may prohibit the use of hair follicle drug testing altogether.

Courts may require drug testing for individuals on probation or during child custody, adoption, and domestic violence cases.

Healthcare professionals sometimes request testing for people at risk of drug or alcohol misuse.

However, it is important to note that drug testing generally requires a person’s written consent.

A hair follicle drug test can take place in a healthcare setting or laboratory, a workplace, or at at your GP

During the test, the tester will remove a small hair sample close to a person’s scalp and send it to a laboratory for overnight testing.

Prescription medications and certain foods, such as poppy seeds, may contain compounds that might lead to false positive results. Hair samples undergo a two-step process to ensure accurate test results.

The first step involves an enzyme-linked immunosorbent assay (ELISA) test, which is a rapid screening method.

If the ELISA test produces a positive result for a particular substance, a technician will retest the hair sample using confirmatory chromatographic testing, such as gas chromatography-mass spectrometry (GC-MS), to help rule out false positives.

People can order at- GP hair follicle testing kits through online providers. These kits include an instruction manual and a pre-paid envelope for mailing the hair sample to the laboratory.
