Handling drugs can result in absorption into the porous nail proteins. Based on reports, the window of opportunity for scanning nails varies, with fingernails having a 3-6-month window and toenails having a time of 8-14 months (due to the fact that toenails take a longer time to grow than fingernails).
A nail bed drug test or a fingernail drug test is a method employed to screen the nails for the presence of drug (s) or its metabolites. Collection of nails for testing is easier and is done under direct supervision of the collector. The results are stable as it stores the drug traces for an extended period of time compared to hair.
Fingernail Drug Testing. Nail specimens, unlike urine samples, yield information about drug exposure time frames measured in months, rather than days. Drugs can be identified in nail clippings two weeks to four weeks following ingestion. A 3 millimeter specimen of fingernail represents up to eight months of collective history of drug exposure.
