Hair drug testing

Visibility into patterns of use over months

For roles or programs where a longer look-back matters more than same-day results, hair testing gives visibility into patterns of use over months, not days.

What makes hair testing different

Up to 90-day window

A standard 1.5-inch hair sample can reflect a pattern of use going back roughly three months, far beyond what urine or oral fluid can show.

Hard to defeat

Unlike urine, hair samples are collected in view and aren't subject to the same substitution or dilution tactics.

Best for patterns, not single events

Hair testing shows a history of use rather than very recent use — pair it with oral fluid or urine if a recent event also needs to be captured.
