PeTH BLOOD ALCOHOL TEST – PEth is born in our red blood cells where it lives as part of the cell membrane. A PEth test in blood gives a 2-3 week history of alcohol abuse. PEth blood alcohol testing checks the level of Phosphatidylethanol in the blood. When alcohol (ethanol) is consumed, the body creates this metabolite. Even after the alcohol leaves the body, PEth stays in the person’s bloodstream. WHY DO I NEED THIS TEST?
