Fingernail Alcohol Testing in Greenville

ISTA-Certified Nail Alcohol Testing with a 90-Day Detection Window

Most alcohol tests tell you what happened in the last few hours. Fingernail and toenail alcohol testing tells a much longer story. At Fastest Labs of Greenville, our ISTA-certified collectors offer this method to individuals and employers throughout Greenville, SC and the surrounding area, including Greer. With more than 10 years in the testing industry, we bring proven process and reliable results to every collection.

Nail tissue retains alcohol biomarkers for weeks after consumption, making this a thorough long-term option available. A single test can capture up to 90 days of alcohol use history from fingernails alone. This detection window is longer than other common alcohol testing methods.

Walk-ins are welcome at Fastest Labs of Greenville, and we strive to serve every client within five minutes. Call us at (864) 479-6880 or request an appointment online.

When to Choose Nail Alcohol Testing

Breathalyzer, urine, and saliva tests are useful for detecting recent alcohol use, but their detection windows are measured in hours, not weeks. When the situation calls for a documented record of consumption over time, nail alcohol testing is a strong choice.

Nail alcohol tests can also help you avoid common problems associated with hair tests, including the use of bleach, or lack of hair. That makes this method practical for large-scale, all-gender testing programs where hair collection isn’t always feasible.

Strong candidates for this test include:

• Pre-employment alcohol screening: Verify a candidate’s alcohol use history before they join your team
• Regularly scheduled employee testing: Maintain an ongoing picture of workforce compliance without relying on short-window tests
• Paired testing programs: Combined with a breath alcohol test, saliva test, and urine test, nail testing can provide both recent and long-term consumption data in one program
• Hair test alternatives: When hair collection isn’t possible, finger and toenail alcohol tests fill the gap

Results are typically available within 3 days. Positive results may undergo additional testing to verify; this can take up to one additional day.

How the Test Is Carried Out

Nail alcohol testing is relatively quick, easy, and non-intrusive. When you arrive, a certified Fastest Labs collector takes a sample clipping from each of the test subject’s ten digits. That’s the entire collection process. No needles, no lengthy procedures.

We strive to serve every client within five minutes of walking through the door. All samples are handled under strict chain-of-custody protocols and processed in clean, state-of-the-art labs. Walk-ins are welcome, and after-hours and 24/7 post-accident service is available for employers who need it.
