HairStat^®

Hair specimens, unlike urine samples, yield information about drug exposure time frames measured in months, rather than days. A 1.5 inch specimen of head hair represents approximately three months of hair growth, and therefore, up to three months of collective history of drug exposure. NailStat^SM also offers similar advantages of hair testing but provides a detection window of up to eight months after the last usage. Urine, on the other hand, for a drug like cocaine, can only yield about three days of prior drug exposure history. HairStat^® is available as a 5-, 7-, 9-, 12- and 14-drug panel. Ketamine is available as an add-on to any profile.

ChildGuard^SM is a modified hair drug test designed to identify environmental exposure in children. The assay is often used by social service agencies involved in custody cases.
