Hair Drug Tests – What is the Turnaround Time for Hair Drug Tests?

Hair drug tests can identify a person’s drug or alcohol use. Hair contains biomarkers that identify specific drugs and substances and can give an employer a quick glimpse into a person’s drug history. A hair sample is typically 1.5 inches long and is collected as close to the scalp as possible. These tests can detect abuse from anywhere between 90 and 180 days ago. They also have the advantage of being easy to collect and difficult to falsify.

A hair drug test can detect the same drugs and substances detected with a urine test. However, the turnaround time for a negative hair test is typically two to three days, while the results of a positive hair test can take a week to confirm. Sometimes, a hair sample can be contaminated, resulting in an inaccurate test result.

The turnaround time for hair drug tests depends on the drug being detected. Some medicines can remain in the hair for five to seven days. In other cases, the drugs can stay in the hair for up to 90 days. Therefore, if you suspect someone has been taking medications for a long time, a hair drug test may not be the best option.

Hair drug tests use ELISA technology to detect drug molecules in hair. These tests detect parent drugs and metabolites. They are also helpful for extended lookback periods. Turnaround time for hair drug tests varies from lab to laboratory. However, the results can be ready in one to five business days for those with a specific date.

Hair drug tests can detect many drugs, including illicit drugs. For example, they can see seven drugs with a seven-panel test. These include marijuana, methamphetamines, amphetamines, cocaine, and opiates. A twelve-panel test can detect drugs like Oxycontin and Percocet.

Hair drug tests may also be performed on body hair. However, body hair differs from head hair so the results can be less reliable and in-depth. Hair drug tests can be conducted on any hair color, including chemical treatments. The hair must be at least 1.5 inches long and 1.5 inches thick for drug testing.

Hair drug tests are often administered at the workplace and are often the preferred method by employers and individuals for employment purposes. A negative hair drug test may indicate ongoing or recent drug use. A confirmatory test method will need to be performed if a negative result is found.

Hair drug tests are accurate and cost-effective. The examination can reveal if a person is using illegal drugs or alcohol. They are also used by courts and school systems to monitor drug use. Psychemedics has been performing hair drug tests for nearly 30 years. They have a proven track record and are widely used by corporations and schools.

Hair specimen collection is simple. A collection kit includes a hair sample pouch, collection foil, and a clear plastic transport bag. The hair specimen collection procedure is relatively simple, and a professional will collect the sample. However, ensure you read the instructions carefully before ordering a hair sample for a test.

A hair follicle drug test can screen for illicit drugs and legal substances. The test requires a sample of 200 strands of hair. It detects drugs and drug metabolites within the hair shaft. Unlike urine drug tests, hair drug tests offer a long detection period. As a result, this is a highly accurate screening method for illicit drugs and alcohol misuse.
