FAQs
Can a nail test be used to prove that a previously taken hair test was inaccurate?
No, the result of any second collected specimen has absolutely no bearing on the validity of the result of any first collected specimen because you have no idea what the donor did between time A and time B.
Will one-time drug use be detected in NailStatSM? How many times would they have to use drugs for it to be detected in nails?
Single doses do not guarantee a positive result. The number of doses required to generate a positive result is highly variable between donors.
Can someone test positive because of passive or environmental exposure?
Yes, environmental exposure versus ingestion must be resolved when interpreting drug tests using nails.
What is the window of detection in nail samples?
Drugs can be identified in nails up to eight months after the last usage. Toenail clippings show over one year of drug use.
How much needs to be collected?
The optimum amount of nail clippings needed is 100 milligrams. If trimming all 10 fingernails, each clipping must be at least 2 millimeters to 3 millimeters long.
How do drugs get into nails?
Drugs are distributed via the blood supply to the nail cells and the nail bed. Nails grow not only in length but in thickness as well. As the nail grows in thickness, it creates layers of drug history.
