What cut off levels are used by HairConfirm?
HairConfirm Drug Test follows the cut-off levels generally accepted industry-wide. These levels are based in part by minimum detection levels for GC/MS confirmation. The cut-off level for each drug varies (depending on the type of drug) and is listed below. Although HairConfirm Drug Tests are designed to detect a very small amount of a drug in the hair, if the amount is below the established cut-off level, you may test negative for that drug even though you may have taken the drug.
