Fingernail Testing – Drug Testing Manicure

What Is Fingernail Testing?

Fingernail drug testing is a great alternative to other testing methods. Just like the rings on a tree can reveal the age of the tree and the climate conditions in which it grew, fingernails on humans can tell the history of drug use in much the same way. When a drug enters the bloodstream its chemicals are carried through the body and absorbed into the keratin fibers that make up fingernails, toenails, and hair

Fingernails are 4 times thicker than a strand of hair and capture more of the substance than hair does; however, fingernail testing cannot show patterns of substance abuse like hair drug testing can. It only indicates that the substance was used, not when.

The detection window is dependent upon the length of the clipping, most common is 3-6 months, but up to 12 months is possible. Nail and hair testing is considered lifestyle testing and not appropriate for one-off drug or alcohol use. 

Clipping fingernails is something everyone is familiar with so the collection of fingernails for drug testing purposes is easily explained and then observed by the collector making it impossible to cheat. Clippings about 1-2 mm from all ten fingers will provide an ideal amount for screening and confirmation.

Benefits Of Fingernail Drug Testing

Fingernail drug testing has one of the longest detection windows of any test. If you want to know if illegal drugs were used within a few days then a good choice is a urine test. But if you are more interested if an employee has a history of drug abuse, then a fingernail test is the best testing method to use.

Hair follicle testing subjects may not want to risk having their hairstyles get ruined but employers may still want that longer detection window that comes with hair testing. Fingernail testing has a longer detection window but the collection samples are not as noticeable and it’s also less risky to mess up someone’s appearance.

Things To Know About Fingernail Testing

 

When a fingernail or toenail collection is done, it is required that the individual shows up with clean nails, free of nail polish, and not having been trimmed for at least 2 weeks. One sufficient sample for a fingernail drug test will essentially consist of the clippings of all 10 fingernails OR all 10 of their toenails.
