Does Swift Do Hair Follicle Test? Understanding Hair Drug Testing Benefits

Does Swift do hair follicle drug testing?

Swift itself does not conduct hair follicle drug testing. Instead, hair follicle tests are performed by specialized laboratories with the proper equipment and accreditation. AMH Nationwide partners with five national lab networks—Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox—to provide hair follicle drug testing services.

AMH Nationwide facilitates the lab order and directs you to a collection site for hair follicle sampling. There is no option for online ordering. For scheduling and questions, call (877) 731-6362.

How does hair follicle drug testing work?

Hair follicle drug testing detects drug metabolites incorporated into the hair shaft from the bloodstream. A small sample of hair, typically 1.5 inches long, is collected close to the scalp and analyzed in a laboratory.

This test can detect drug use within approximately 90 days, making it useful for identifying long-term substance use patterns. Hair testing is non-invasive, and collection is supervised to prevent tampering.

Which labs perform hair follicle drug testing through AMH Nationwide?

AMH Nationwide routes hair follicle drug tests to one or more of these five national lab networks:

Each lab is accredited and follows strict federal and industry standards to ensure accurate and reliable results.

How reliable is hair follicle drug testing?

Hair follicle drug testing is highly reliable for detecting drug use over a 90-day period. The testing methods used by AMH Nationwide’s lab partners are validated and comply with SAMHSA guidelines where applicable.

All non-negative results are reviewed by a certified Medical Review Officer (MRO) to verify and interpret findings before reporting. This review reduces the chance of false positives and ensures proper result handling.

Who typically orders hair follicle drug testing?

Hair follicle drug testing is commonly ordered by employers for pre-employment screening or ongoing workplace drug monitoring, especially for non-DOT regulated positions.

Courts, probation officers, and individual clients may also request hair follicle testing to monitor abstinence or substance use history. AMH Nationwide supports all authorized requesters by providing lab orders and collection site coordination.

Can hair follicle drug testing detect recent drug use or passive exposure?

Hair follicle testing is less effective at detecting very recent drug use within the past week because drugs take time to incorporate into hair. It is primarily used for long-term detection up to 90 days.

Passive exposure to drugs, such as environmental smoke, is unlikely to cause a positive hair test due to the way drugs enter the hair shaft via bloodstream rather than external contact.
