Alcohol Testing Services We Offer

We offer a full range of alcohol testing options for individuals and organizations across the greater Seattle area. Whether your requirement comes from a workplace policy, DOT testing requirements, or a legal matter, we help you choose the right test. Our certified collectors can walk through detection windows with each client before the visit so you arrive knowing exactly what to expect.

Our alcohol testing services include:

• Breath Alcohol Testing: A fast, noninvasive method that measures current alcohol levels. It’s the standard for DOT compliance and most workplace programs.
• EtG / EtS Urine Testing: Extends the detection window well beyond a breath test, often up to several days, making it common for monitoring programs and court-ordered testing.
• EtG Hair Testing: Reaches back up to 90 days, making it one of the longer detection windows available and a practical choice for extended monitoring requirements.
• Saliva Alcohol Testing: A simple, effective option for detecting recent alcohol use, often used for workplace or compliance purposes.
• Nail Testing: Provides a longer lookback period similar to hair testing, used when extended detection is required.
• PEth Testing: Detects chronic or heavier alcohol use over a multi-week period and is frequently ordered in legal or custody matters.
• Random & Scheduled Testing Programs: Designed for employers maintaining safe, compliant workplaces under DOT or non-DOT policies.
• Mobile and On-Site Testing: Flexible solutions for group testing or workplace convenience when coming to us isn’t practical.

If you’re unsure which test applies to your situation, our team can walk you through every option before your visit. We follow strict protocols and current technology standards to support accurate, confidential results.

Locally Owned, Community Committed

David and Rachel George opened this location because they wanted to serve their community, not just run a testing business. David is a 26-year U.S. military veteran, and both he and Rachel are Tacoma natives with deep roots in the King County area. That background shapes everything here: the accountability the team brings to chain-of-custody handling, the patience extended to clients navigating court orders, and the direct communication that makes a stressful visit easier to get through.

David and Rachel have personal connections to substance abuse recovery, and that informs how every client interaction is handled. They didn’t build this location to be transactional. Being named the 2025 Fastest Labs Franchisees of the Year reflects exactly that. It’s the kind of recognition that comes from clients who felt respected, not just processed. Fastest Labs of South Seattle carries more than a decade of brand experience, but what makes this location different is who runs it.
