Hair Testing

Hair Testing

Hair testing is a process in which hair specimens are analyzed for illegal drugs.  When a drug is ingested, it enters the blood stream and is broken down to a specific metabolite.  When a hair sample is screened, both the parent drug and the metabolite are isolated.  Any samples that screen positive are confirmed using GC/MS (Gas Chromatography/Mass Spectrometry) technology.

In order for a sample to confirm positive at the established cut-off level, the metabolite of the drug will only be present if the donor has physically ingested the drug(s) detected. 

When compared to other forms of testing (urine, blood, oral fluids), hair samples can detect a longer period of drug use.  For example, urinalysis can only detect most drugs within 2-3 day of use with the exception of marijuana, which may be detected for a slightly longer period of time.  With hair samples, the only time limitation for detecting drug use is imposed by the length of the donor’s hair.  Then industry standard is to test 1.5 inches of hair, which provides a 90-day history of the donor’s drug use.

Courts in a number of jurisdictions as well as in cases involving both civil and criminal matters have upheld the validity of hair testing. 

• Hair testing permits the detection of drugs up to 90-days
• The hair-test sample cannot be adulterated or substituted
• Collection is simple & safe-no bodily fluids to handle
• No need for custom collection facilities
• Can test for: Cocaine (benzoylecgonine), Marijuana, Opiates (Codeine) , Morphine, Amphetamine/Methamphetamine/Ecstasy, Phencyclidine (PCP)
• Turn-around-time: Screen: 24 hours, Confirmation: 48 hours


What's the advantage of testing with hair?   One of the most important advantages is that a hair drug test can detect drug use anytime during the past 90 days. A urine or saliva drug test, on the other hand, can detect drug use for the past two to three days for most drugs. This long window of detection allows programs to continuously monitor a subject's drug use with less frequent testing.
