Fingernail Alcohol and Drug Testing

Window of Detection and Collection

Nails provide up to 6 months of drug use history and up to 3 months of alcohol history. Biomarkers are detectable in nails as early as one week after drug or alcohol use. The window of detection for drug or alcohol ingestion depends on the substance used, the amount used, and personal metabolism. Just like hair and urine, a negative result is not proof of abstinence, just the lack of evidence.

A 2-3mm clipping, about the thickness of a quarter, from the end of each fingernail provides the optimal sample.

Not enough fingernail: Wait 1-2 weeks. What is positive today will still be positive in 2 weeks. We never mix fingernails and toenails in the same sample.

The Benefits of Fingernail Testing

Fingernail, made of keratin like hair, is emerging as a popular specimen type for drug and alcohol testing. It is simple to collect, easy to ship and store, and is at the cutting edge of drug and alcohol testing.

  • Nail testing cannot be adulterated.
  • Nail keratin is 4 times thicker than hair.
  • Nail often captures more of a biomarker than hair.

As nail grows in thickness and length, biomarkers build up in the nail at the germinal matrix and along the nail bed, collecting the full history of drug use.

How nails grow is important for biomarker testing.

The nail originates in the germinal matrix (under the nail closest to the skin). The hardened material forming the nail plate grows across the nail bed, which is rich in capillary blood flow. As the nail grows in length, material is added from underneath such that the nail lengthens and thickens, as it grows outward toward the fingertip. The portion of the nail extending past the fingertip is called the free edge, the piece that the collector will clip when clipping your nails. The entire process takes up to 6 months depending on the health of the individual.

Drug and alcohol biomarkers are trapped in fingernail by three main routes:

  • Blood flow in the germinal matrix deposits drug and alcohol biomarkers into the nail when it is formed.
  • Blood flow in the nail bed deposits drug and alcohol biomarkers in the nail as it thickens.
  • Sweat and oil of the skin surrounding the nail deposits drug and alcohol biomarkers into the nail.

Nail and Hair samples capture the same drugs.

  • Non-intrusive, donor collected sample. Fingernails are collected by the donor in front of a trained collector.
  • Minimal impact on the donor/s appearance.
  • All samples are screened on state-of-the-art instruments and presumptive positives are confirmed before reported out.
