What is a nail drug test?
A nail drug test is a laboratory analysis that detects the presence of drugs or their metabolites in fingernail or toenail clippings. It offers a longer detection window than urine or saliva tests because drugs incorporate into the nail matrix as nails grow. The test is used to identify past drug use over weeks to months.
Who orders a nail drug test?
Nail drug tests are ordered by employers, legal entities, healthcare providers, and individuals needing extended drug use history. They are useful when a longer detection window is required or when other specimen types are unsuitable. The test is common in forensic cases, workplace compliance, and substance abuse monitoring.
What is the detection window for a nail drug test?
The detection window for a nail drug test typically ranges from 1 to 6 months, depending on nail growth rate and the drug involved. Nails grow approximately 3 millimeters per month, and drugs become embedded in the keratin matrix. This test detects drug use longer than urine or saliva tests, which cover days to weeks.
How is nail drug test collection performed?
Nail drug test collection involves clipping fingernails or toenails using a clean instrument at an authorized collection site. The sample size must meet lab requirements and avoid contamination. AMH Nationwide directs the requester to one of five national lab networks for collection: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.

Every non-negative result is reviewed by a certified Medical Review Officer (MRO) to ensure accuracy and address any legitimate explanations. Results are reported to the ordering party following strict chain-of-custody and confidentiality protocols.
