Fingernail / Toenail Drug Testing

Because fingernails and toenails contain the bio-material keratin, which is also found in hair, deposits of drug and drug metabolites can be detected in the nails using a similar method. A major advantage of nail testing over hair testing is the numerous test panels available . Here is a complete list of testing panels offered, what they test for and the costs:

5 Panel

Amphetamines
Cannabinoids
Cocaine
Hydrocodone
Opiates
Oxycodone
Phencyclidine (PCP)

 

7 Panel

Amphetamines
Barbiturates
Benzodiazepines

A nail test consists of 10 clippings of either fingernails or toenails (nail scrapings or shavings are not used). Depending on the source of the sample (fingers or toes), a nail test can detect drug use between 6 and 12 months, even with regular clippings and trimmings.

Fingernails and toenails do not grow at the same rates. This allows for different detection time frames depending on the source of the sample. Generally fingernails grow between 3 - 5 millimeters each month while toenails grow at a much slower rate of about 1 millimeter each month. Because nails grow at such a slow rate, a single drug use will not typically be detected during a nail analysis and once a drug is ingested it could take 2 - 4 weeks for the nail to grow enough for the test to detect use.

All nail tests are confirmed by GC/MS and are eligable for review by a Medical Review Officer (MRO) in the event of a false positive due to legitimate prescription drug use.
