When you need a longer lookback period than many urine tests provide, nail drug testing can be a practical option. Mobile Drug Testing provides confidential fingernail drug testing in Memphis for individuals, employers, attorneys, courts and agencies. Call 901-318-7214 to confirm the correct panel and schedule your appointment.

What nail drug testing can show
Nail testing may identify drug use over a longer historical period than many urine tests. The approximate detection window can extend for several months, but it varies by the substance, specimen, individual growth rate, collection amount and laboratory method. Nail testing does not determine the exact date or time a substance was used.
Available nail testing options
- 10-panel fingernail drug testing
- Expanded 16-panel fingernail drug testing
- ETG nail alcohol testing when appropriate
- Observed professional specimen collection
- Legal chain-of-custody collection for court or agency matters
- Personal-information testing when legal documentation is not required
Panel contents differ. Tell us which substances must be included before your appointment so we can confirm the correct laboratory order.
Common reasons for nail testing
- Court or attorney-requested testing
- Department of Children’s Services or family-service matters
- Child-custody cases
- Workplace or return-to-work requirements
- Personal accountability and monitoring
- Situations where head or body hair is unavailable
Preparing for your appointment
Do not clip your nails immediately before the collection. A sufficient amount of usable nail specimen is required; some orders may require approximately 150 mg. Remove artificial nails or nail coverings when possible and tell us about any condition that may affect collection. Bring a government-issued photo ID and any court order, agency paperwork, employer authorization or laboratory account information.
Legal versus personal testing
Legal testing requires documented identity verification, chain-of-custody procedures and laboratory reporting appropriate for the requesting party. If the result may be used in court, with an attorney, by an employer or by an agency, tell us before collection. A personal-information test may not be suitable for official use.
Frequently asked questions
How far back does a nail drug test go?
Nail testing can provide a several-month historical window. The precise period cannot be guaranteed and depends on the specimen and laboratory method.
Can toenails be collected?
Toenails may be an option in some circumstances, but acceptance depends on the ordered test and laboratory requirements. Call before your appointment.
What happens if there is not enough nail?
The collection may need to be rescheduled or another approved specimen type may be recommended. For some alcohol-testing situations, hair ETG may be considered when an adequate nail specimen cannot be collected.
Is nail testing the same as a DOT drug test?
No. DOT drug-testing rules require approved specimen types and procedures. Nail testing is not a substitute for a federally regulated DOT test.
