PEth (Phosphatidylethanol) Test

The PEth (Phosphatidylethanol) Test is a highly sensitive blood test used to detect and measure Phosphatidylethanol, a direct biomarker of alcohol consumption. This test is commonly used to:

• Assess long-term alcohol intake (typically over the past 2 to 4 weeks)
• Monitor alcohol use in clinical settings or rehabilitation programmes
• Support diagnosis of alcohol-related disorders

The PEth Test is valuable due to its ability to provide an accurate picture of alcohol consumption, even in cases of moderate or heavy drinking, making it a reliable tool for monitoring alcohol-related health risks and guiding treatment decisions.
