Hair Follicle Drug Testing (90-Day) is a method that detects drug metabolites in hair strands, reflecting drug use over the past three months. This test analyzes the hair shaft, which grows approximately half an inch per month, providing a [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) of about 90 days. It is commonly used for employment screening, legal cases, and monitoring compliance in non-DOT safety-sensitive roles. The test requires a small sample of hair, usually taken from the crown area, which is then sent to one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. All non-negative results are reviewed by a certified Medical Review Officer to ensure accuracy and proper interpretation. PROCESS ## How is Hair Follicle Drug Testing (90-Day) Collected and Processed? Hair Follicle Drug Testing (90-Day) collection involves cutting a small section of hair close to the scalp, typically about 1.5 inches in length to cover the 90-day detection window. Collection must be done in person at an authorized collection site. AMH Nationwide directs you to a convenient location; there is no online ordering or at-home collection option. After collection, the sample is sent to one of the five national lab networks for analysis. The labs use sophisticated testing methods to detect common drugs of abuse within the hair shaft. Any non-negative screen undergoes review by a Medical Review Officer to confirm results and rule out potential false positives.

Hair Follicle Drug Testing (90-Day) detects drug metabolites embedded in the hair shaft. It is effective for identifying use of commonly abused substances within the prior three months. The standard panel typically includes: This test is not suitable for detecting very recent drug use (within days). Instead, it excels at identifying long-term patterns of drug use. Amphetamines (including methamphetamine) Cocaine Marijuana (THC metabolites) Opiates (such as heroin, morphine, codeine) Phencyclidine (PCP) Additional drugs may be included depending on the testing panel WHO ORDERS ## Who Uses Hair Follicle Drug Testing (90-Day)? Employers often use Hair Follicle Drug Testing (90-Day) for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) screening or ongoing employee monitoring in safety-sensitive or regulated industries where long-term drug use detection is important. Legal professionals and [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers may also order these tests to monitor compliance. Because hair testing is not approved for DOT safety-sensitive roles, those positions require federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing protocols. Hair tests serve as a non-DOT alternative with an extended detection window. ## Schedule Hair Follicle Drug Testing (90-Day) Today Call (877) 731-6362 to find a collection site near you and arrange your hair follicle drug test with nationwide lab processing and expert result review.

Yes, AMH Nationwide offers upsell options for extended hair follicle drug testing covering 6, 9, or 12 months.
