Hair and nail drug testing for months of detection history.

“Hair follicle drug test” is a common name for hair drug testing. The laboratory generally tests cut hair strands, not the follicle beneath the skin. The collector takes the sample close to the scalp according to the laboratory’s requirements.

A standard 1.5-inch head-hair sample can represent approximately 90 days of drug-use history. The actual period depends on hair length, growth, the substance, and the laboratory method. Hair testing does not establish the exact day of use.

Call before your appointment so we can check the laboratory’s specimen requirements. Body hair or nails may be an option for some Non-DOT orders, but the laboratory and requesting organization must accept the alternative. Do not assume a different specimen will satisfy your order.

Tell us about short hair or recent hair treatments before your visit. Ask for the collection instructions for your ordered test before cutting your hair. The collector must obtain enough suitable material for the laboratory.

The substances tested depend on the hair panel selected. Review the substance list on the hair panel card and match it to your order. If a specific drug is required, ask us to confirm that it is included before collection.

Hair tests may be suitable for a Non-DOT employer, court, or monitoring program when that organization accepts the specimen and panel. Required identity checks and chain-of-custody documentation must be arranged from the start. Acceptance depends on the receiving organization’s rules.

Turnaround varies by hair panel and any additional laboratory analysis. Call (480) 210-1016 with your testing order for the current estimate and price before booking. Hair tests do not provide an instant result at collection.

No. Hair specimens are not authorized for DOT drug testing. We offer hair testing for Non-DOT purposes, subject to the requesting organization’s requirements.
