Hair Drug Test
drug test, drug abuse, drug screen,
This test can determine the previous use of 6 commonly used illicit drugs, namely cocaine, marijuana, opiates, methamphetamine, phencyclidine and ketamine.
Hair testing is the most accurate and effective method of finding users of drugs of abuse. Using a small sample of hair cut at the scalp, hair analysis evaluates the amount of drug metabolites embedded inside the hair shaft.
Each ½ inch of head hair provides a 30-day history of drug use. The standard for the industry is to test 1.5 inches, which provides a 90-day history of the donor’s drug use.
If no head hair is available, body hair can be used. Bleaches, shampoos and external contaminants (i.e. marijuana smoke) have no known impact on test results. Since each hair has it own directly blood supply, the ingestion of any illegal drugs will be transport by blood and trapped by the hair, which can be revealed by analyzing a small sample of hair. Our testing method measures the drug molecules and the metabolites embedded inside the hairshaft, eliminating external contamination as a source of a positive test result.
