Objective, windowed alcohol-consumption markers for abstinence and treatment monitoring.
Blood + urine
72 hrs
Physician-reviewed
What this panel measures
- PEth — a direct blood marker of alcohol use over the past 2–4 weeks
- EtG — a urine metabolite detecting recent use within roughly the past few days
- CDT — a blood marker sensitive to sustained heavy drinking
Why providers order it
- Abstinence monitoring for treatment programs
- Return-to-duty, legal, or family-custody requirements
- Long-term compliance monitoring with objective, windowed markers
- Transplant and medical-program protocols
No preparation is required. Collection is documented per your program's protocol, and results are released only to authorized parties.
Alcohol Use Biomarkers: frequently asked questions
How long does alcohol stay detectable?
Each marker covers a different window: EtG (urine) detects use within roughly the past 80 hours, PEth (blood) reflects the past 2–4 weeks, and CDT indicates sustained heavy drinking over recent weeks. Using several together gives both short- and long-term coverage.
Can PEth be fooled by mouthwash or hand sanitizer?
No. PEth only forms when alcohol is actually metabolized by the liver at meaningful levels. Trace environmental exposure does not produce it — unlike urine EtG, which can occasionally flag alcohol-based products.
Who receives the results?
Results go only to recipients authorized under your program's consent and collection protocol.
