At-Home Hair Drug Test Kit: FAQ | AMH Nationwide

At-Home Hair Drug Test Kit FAQ for Reliable Long-Term Drug Screening

The at-home hair drug test kit FAQ addresses common questions about using hair samples for drug detection. This test detects drug use over a 90-day period with samples collected at local labs within AMH’s network. Call (877) 731-6362 to schedule a collection or get more information.

TEST BASICS

What is an at-home hair drug test kit?

An at-home hair drug test kit involves collecting a small hair sample to detect drug use over approximately 90 days. The kit provides instructions for obtaining a sample, which must be collected at a local collection site affiliated with AMH’s national lab networks. The sample is then sent to one of five labs for analysis.

How long can drugs be detected using a hair drug test?

The hair drug test detects drug use within the past 90 days or roughly three months. This is because hair grows about half an inch per month, and labs typically test the most recent 1.5 inches of hair closest to the scalp to assess drug exposure over this period.

LAB NETWORKS

Which labs process the at-home hair drug test kit samples?

Samples collected for the at-home hair drug test kit are routed through one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. Each lab follows strict protocols and sends non-negative results to a certified Medical Review Officer for evaluation.

USAGE AND ORDERING

How do I get an at-home hair drug test kit and complete the collection?

AMH provides the lab order and directs you to a local collection site; there is no online ordering of the test kit. To initiate testing, call (877) 731-6362 to receive instructions and find a nearby collection location where a trained technician will collect your hair sample.

TEST LIMITATIONS

What are the limitations of the at-home hair drug test kit?

The hair drug test does not detect very recent drug use within the past 7 days, as drugs take time to incorporate into hair. It is not suitable for DOT-regulated safety-sensitive testing, which requires federally certified urine protocols. Hair testing is mainly used for non-DOT employment or legal screenings.

RESULTS AND REVIEW

How are the results from the hair drug test reviewed and reported?

All non-negative hair drug test results undergo review by a certified Medical Review Officer (MRO) to ensure accuracy and interpret findings. The MRO may contact the individual for medical explanations before finalizing the report. Results are then provided to the requester according to their instructions.
