The InvitroPro Hair Test detects the following 13 Illicit & Prescription drugs:
Hair testing is a process in which hair specimens are analyzed for the use of illicit drugs. When compared to other forms of testing, hair samples can detect a much longer period of drug use. For example, urinalysis can only detect most drugs within 2-3 days of use. After this period, a donor will be free of the drug, test negative and slip through the screening process. By comparison, the industry standard is to test 1.5 inches of head hair for approximately 90 days of history. This is important in pre-employment testing where most candidates are aware that a drug test might be required and can otherwise abstain accordingly.
Body hair can also be used for testing. However, while body hair is generally acknowledged as representing a more distant time frame than head hair, the approximate time period cannot be identified to to the high variability of growth rates.
One of the best benefits of a hair test is that there are no known successful commercial adulterants for hair tests. The recommended use of normal hair care products/procedures such as shampoos, dyes, permanents, relaxers, bleaches etc. do not have a significant effect on results. The effects of these products were reviewed by the FDA.
