Hair Follicle Testing

Longer-lookback screening for employers, programs, and specialized verification needs.

Hair follicle testing provides a longer detection window than standard urine screening, typically covering up to 90 days of history. It is commonly requested by employers, court programs, and compliance officers who need a broader look-back period.

A small hair sample is collected on-site by trained staff. Bring a valid government ID and any paperwork from your requesting agency or employer. No special preparation is needed before your visit.
