PEth Alcohol Test Screen
The ICare PEth Alcohol Test Screen is an advanced laboratory test that measures Phosphatidylethanol (PEth), a direct biomarker of alcohol consumption. Unlike breath or urine alcohol tests that detect recent drinking, the PEth test provides a reliable assessment of alcohol use over the previous 2–4 weeks, making it one of the most accurate methods available for identifying repeated or ongoing alcohol consumption.
Because PEth is formed only when alcohol is present in the body, it offers exceptional specificity and is widely used in healthcare, transplant medicine, substance use treatment programs, occupational health, legal proceedings, and monitoring for alcohol abstinence.
Whether testing is required for medical care, employment, legal compliance, or personal health monitoring, the ICare PEth Alcohol Test Screen provides confidential, accurate results you can trust.
With ICare's concierge mobile laboratory services, advanced alcohol testing is delivered directly to your home, office, or preferred location.
What Does This Test Measure?
The PEth Alcohol Test measures Phosphatidylethanol (PEth) in red blood cell membranes.
PEth is produced only when ethanol (alcohol) is present in the bloodstream and cannot be formed from foods, medications, or non-alcoholic products.
Because PEth remains detectable for approximately 2–4 weeks, it provides valuable information about patterns of alcohol consumption over time rather than detecting only recent drinking.
PEth testing may help distinguish between:
No recent alcohol consumption
Light or occasional alcohol use
Moderate alcohol consumption
Heavy or repeated alcohol use
Your healthcare provider will interpret your results using established laboratory reference ranges and your individual clinical circumstances.
Who Should Consider This Test?
The PEth Alcohol Test Screen may be recommended for individuals who:
Are participating in alcohol recovery or monitoring programs
Require testing for legal or court-ordered purposes
Are undergoing transplant or surgical evaluations
Need occupational or professional monitoring
Are participating in wellness or employee assistance programs
Want objective monitoring of alcohol abstinence
Want confidential testing for personal health awareness
This test provides highly reliable information for both medical and non-medical purposes.
