Fingernail Drug Testing Services

Highly stable, simple to collect, and easy to ship and store, fingernails provide a test sample that is at the cutting edge of drug and alcohol testing.


Fingernails are made up of keratin, the same material that hair is made of. As the nail grows, substances can pass from the blood vessels below the nail into the keratin fibers where they become trapped.

Fingernails are four times thicker than the typical strand of hair and often capture more of a substance than hair can. Biomarkers become locked in keratin fibers along the entire length of the nail, and can be detected up to 3-6 months after drug or alcohol abuse. Environmental exposure to illicit substances can be detected immediately in nail samples.


When drugs or alcohol are ingested, biomarkers can be found in nails as early as 1-2 weeks after. The time period during which drug or alcohol ingestion can be detected depends on the substance used, the amount used, and personal metabolism. Fingernail samples are clipped and collected by the donor in front of a trained collection staff member.


A clipping of 2-3 mm long (about the width of a quarter) from all ten fingernails will give about 100 mg of sample, the ideal amount for screening and confirmation. Larger profiles may require more. We recommend weighing the specimen on a jeweler’s scale.

Hair Drug Testing in Northwest Arkansas

Recently, hair testing has come to be seen as a powerful tool for the detection of drug and alcohol abuse. Hair provides a long-term history of drug and alcohol abuse by trapping biomarkers in the fibers of the growing hair strand. When collected close to the scalp, hair can provide up to a 3 month history of alcohol and drug abuse. Drug and alcohol biomarkers can appear in scalp hair 1-7 days after the last use.


Hair offers a sample that is simple to collect, somewhat difficult to adulterate, and easy to ship. A 1.5 inch sample of about 200 strands of hair (about the size of a #2 pencil) closest to the scalp will give 100mg of hair, the ideal sample for screening and confirmation. For EtG, add-ons and/or tests above 10-panel, 150mg of specimen is recommended. We recommend weighing the specimen on a jeweler’s scale.

Collecting a hair sample for a drug test

If scalp hair is not available, an equal amount of body hair may be collected. When referring to head hair, we are referring to scalp hair only. Body hair refers to all other types of hair (facial, axillary, etc). Our hair drug tests are common for Northwest Arkansas business owners wanting to be safe with their workforce.
