The 16 Panel Nail Drug Test through USDTL screens for 16 drug classes using a fingernail or toenail sample, providing a significantly longer detection window than urine testing and standard 90-day hair testing.

Specimen Collection Options
At checkout, donors select a nail specimen type based on availability. Fingernail collection is recommended whenever possible.
- Fingernail Collection (Recommended): Clippings from all 10 fingers, approximately 2 to 3 mm in length (about the depth of a nickel). Detection window up to approximately 6 months. Collection must take place at an approved collection site with trained staff present; fingernail specimens cannot be substituted with toenails.
- Toenail Collection (Extended Detection Window): Used when fingernail collection is not possible. Toenail clippings may provide a longer historical detection window due to slower nail growth, and results may reflect drug exposure occurring approximately 6 months or longer prior to collection. Detection windows vary by individual and drug type, and toenail collection may require special scheduling or approval.
- Insufficient Sample Available: Donors who are unsure whether they have enough nail material should contact ReliaLab Test before collection. An insufficient specimen may result in a cancelled or incomplete test.
- Court or Legal Ordered Testing: May require additional documentation, chain-of-custody procedures, and a verified collection location that follows legal testing requirements.
Fingernail and toenail specimens cannot be combined in the same collection. The sample must be entirely fingernail or entirely toenail clippings.

Urine tests detect recent drug use within the past 1–5 days for most substances. Hair tests detect use over a 90-day window and cannot be defeated by short-term abstinence.
