How To Perform Nail Specimen Collections for Drug Testing

Did you know that fingernails and toenails make excellent specimens for drug testing?  The same drugs that can be detected in samples like urine, oral fluid and hair can also be detected in nails.  This means when that employee or candidate shows up for their drug test bald with their body completely shaved, we’ve got another surprise for them!

As you will see in this video, all ten fingernail or toenail tips are clipped first.  The detection period from clippings only is for 30 days, 6 months ago.  Do you want to know if someone was using drugs during the entire six month period?  If so, the collector will then lightly shave the surface of all ten nails.  The detection period between the lunula (the “white moon” of the nail) and where the clippings ended is about 5 months. 

Both the clippings and shavings are then submitted to ExperTox for testing.  Here is how the collection is performed:
