The HairConfirm™ personal forensic hair analysis drug of abuse testing service is the only at home drug testing kit that provides a *history (up to several months) of current or previous drug use for the five most abused illicit drugs and drug categories: Methamphetamines including Ecstasy , Marijuana, Opiates, Cocaine and Phencyclidines (PCP) without the need for urine specimen collection.
The only sample required is a small lock of the test subject's hair (approximately the size of a shoelace tip) taken at the scalp line.

Confidential and non-invasive, The HairConfirm™ drug test provides a qualitative determination of past drug use over a period of approximately three (3) months using forensic laboratory analysis.
PRINCIPLE
The presence of drugs in hair is based on a simple principle. Drugs which are ingested into the body circulate in a person's bloodstream which nourishes developing hair follicles. As a result, trace amounts of the target drug or drug metabolite are deposited in the hair follicle and become entrapped in the core of the hair shaft as it grows out from the hair follicle. Normal growth rates for human hair are approximately one-half inch per month. By testing for the presence of drugs in the hair shaft core on a given length of hair, a historical record can be achieved on past drug usage based on the length of the hair sample submitted measured from the scalp line. For example; if a 1.5" length hair sample measured from the scalp line is submitted, and knowing that on average head hair grows at the rate of .5" inch per month, then it can be assumed that a positive test result would imply that a drug was consumed sometime in the past 3 month period. Since target drug or drug metabolite residues are chemically and structurally stable for an extended period of time within the hair shaft core, they cannot be externally washed, bleached, chemically treated or flushed out of the hair structure. Consequently there is little possibility of sample contamination or manipulation. For this reason many courts and legal entities have chosen a forensic hair drug test as the preferred method of drug testing. Gas chromatography/mass spectrometry (GC/MS) forensic laboratory analysis of the hair shaft from an individual can achieve highly accurate drug test results and provide a historical use record. Generally it takes approximately 5 days for drugs to show up in a person's hair and will continue to be detectable in new hair growth for several months
