It is used when extended drug history is needed. AMH Nationwide routes collections to five national labs and reviews all non-negative results with a Medical Review Officer. Call (877) 731-6362. OVERVIEW ## What is a nail drug test and how does it work? A nail drug test analyzes drug metabolites embedded in the keratin of fingernails or toenails. It captures drug use over weeks to months, longer than [urine](https://amhnationwide.com/urine-drug-testing/) or saliva tests. The test involves clipping nail samples, which are sent to one of AMH Nationwide’s five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. Each sample undergoes laboratory analysis with confirmatory testing as needed. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## How long can a nail drug test detect drug use? A nail drug test can detect drug use from approximately 7 days up to 90 days prior to collection, depending on nail length and growth rate. This extended detection window makes it valuable for employers or legal cases requiring a longer look-back period. Compared to other testing methods, nail testing provides the longest detection timeframe. | Test Type | Typical Detection Window | | --- | --- | | Urine Drug Test | 1-4 days | | Saliva Drug Test | 1-3 days | | Hair Drug Test | Up to 90 days | | Nail Drug Test | 7 to 90 days | TYPES OF NAIL TESTS ## What is the difference between fingernail drug test and toenail drug test? Both fingernail and toenail drug tests detect drug metabolites in keratin, but there are practical differences. Fingernail samples are easier to collect and may reflect more recent drug use due to faster growth, while toenail samples grow slower and may capture a longer history. The choice depends on availability of samples and the specific testing requirements. Fingernail Drug Test: Faster growth, reflects recent weeks. Toenail Drug Test: Slower growth, may show longer-term use. Both are analyzed by the same lab procedures and reviewed by a Medical Review Officer.

After collection, the nail samples are sent to one of AMH Nationwide’s five national labs for testing. Each sample undergoes screening using validated analytical methods. Any non-negative results are reviewed by a certified Medical Review Officer (MRO) who evaluates medical explanations before final reporting. This process ensures accuracy and compliance with testing standards. APPLICATIONS ## Who typically orders a nail drug test and why? Nail drug tests are ordered by employers, legal entities, and rehabilitation programs requiring extended detection of drug use history. They are useful when urine or saliva tests do not provide a sufficient detection window. They are not used for DOT-regulated safety-sensitive testing, which requires federally certified urine testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Nail testing is reserved for non-DOT roles or specialized needs. PRICING ## What does a nail drug test cost?
