Hair Follicle Drug Tests
Hair follicle drug tests are a multi-drug kit that use a small sample of hair at the scalp. They evaluate the amount of drug metabolites embedded in the hair shaft. These metabolites are confirmed using Enzyme Immunoassay (EIA) and Gas Chromatography / Mass Spectrometry (GC/MS) Technology and are tested within 99.9% accuracy.
The tests provide a very detailed and accurate substance use report that shows up to 90 days of drug use. The tests screen for 5 to 7 illicit drugs.
