Overview
What PEth Alcohol Test is
PEth (phosphatidylethanol) forms in red blood cells only when alcohol is present, which makes it a direct marker of alcohol use.
It is commonly requested for court, probation, monitoring and treatment programs. Collected as whole blood or a blood spot.
Some tests may require an order from a licensed provider. We'll let you know what's needed when you book.
