PEth Alcohol Blood Test

The Phosphatidylethanol (PEth) test is a highly accurate blood-based biomarker used to detect direct alcohol consumption. Unlike other markers that can be influenced by liver health or external factors, PEth is only formed in the presence of ethanol, making it the gold standard for verifying abstinence or monitoring chronic drinking patterns.

Key Features:

• Detection Window: Identifies alcohol consumption within the past 2–4 weeks.
• High Specificity: Not affected by incidental exposure to alcohol-based products (hand sanitizers, mouthwash).
• Reliability: Differentiates between casual/social drinking and heavy/chronic consumption.
• Purpose: Frequently used for legal cases, child custody, and professional monitoring programs.
