Nail Drug Test: How It Works | AMH Nationwide
Nail Drug Test How It Works for Reliable Substance Detection
A nail drug test how it works involves collecting a small clipping of fingernail or toenail to detect drug metabolites embedded in the keratin. The sample is sent to one of five national labs for screening, confirmation, and review by a certified Medical Review Officer. Call (877) 731-6362 to begin the process.
How is the nail sample collected for a nail drug test?
The nail drug test how it works begins with the collection of a nail clipping sample. A trained collector trims a small portion of fingernail or toenail from the individual, ensuring enough material is gathered for accurate testing. The sample is then securely packaged and labeled to maintain chain of custody before shipment to the laboratory.
Which laboratories analyze the nail samples?
Nail drug test how it works includes routing the sample to one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. These labs specialize in forensic toxicology and follow strict protocols to ensure accurate and reliable results.
What testing methods are used on the nail sample?
The nail drug test how it works involves two main phases: initial screening and confirmation. The screening phase uses immunoassay techniques to detect the presence of drug metabolites. If the screen is non-negative, the sample undergoes confirmation testing using highly sensitive methods such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS).
How does the Medical Review Officer (MRO) contribute to the process?
Every non-negative nail drug test how it works includes review by a certified Medical Review Officer. The MRO evaluates the lab results alongside any medical history or prescription information provided. This step ensures that legitimate medical explanations are considered before finalizing results.

How is chain of custody maintained during the nail drug test?
Maintaining chain of custody is critical in the nail drug test how it works. From collection through lab analysis and reporting, all samples are tracked with documentation and secure handling to prevent tampering or contamination. This ensures test integrity and legal defensibility.
How are nail drug test results reported?
After the MRO review, the final nail drug test how it works report is issued to the authorized requester. The report details whether drugs were detected and includes any MRO comments. Negative results confirm absence of tested substances within the detection window, while confirmed positives are clearly identified.
Common Questions
A nail drug test can detect a variety of substances including opioids, cocaine, amphetamines, cannabinoids, and benzodiazepines. The exact panel depends on the test ordered. Detection is based on metabolites incorporated into the nail keratin over weeks to months.
Results typically take between 5 to 10 business days after the lab receives the sample. Screening, confirmation, and MRO review require time to ensure accuracy and thorough evaluation.
Nail drug testing is best for detecting drug use over a longer period, usually up to 3 to 6 months. It is not ideal for detecting very recent use within days because metabolites take time to incorporate into nail tissue.
No, nail drug tests are not accepted for DOT-regulated safety-sensitive positions. DOT requires federally certified urine testing under 49 CFR Part 40. Nail tests are typically used for non-DOT roles.
A trained collector at an authorized collection site performs the nail clipping to ensure proper sample size and chain of custody. AMH Nationwide directs individuals to these sites after coordinating the lab order.
If the initial screen is non-negative, the sample undergoes confirmation testing with precise analytical methods. Then, a certified Medical Review Officer reviews the results along with any medical information before reporting a final determination.
