Phosphatidylethanol (PEth) Alcohol Test

PEth, Ethyl Alcohol Biomarker
Sample Report
Specimen Type: Blood


Phosphatidylethanol (PEth) Alcohol Test

The PEth Blood test measures levels of phosphatidylethanol, an alcohol specific biomarker, in the blood.  PEth is used to detect prolonged or heavy "binge" alcohol consumption.  It is typically detectable for 2-3 weeks but may be detectable for longer depending on how much alcohol was consumed or for how long.  PEth levels above 20 ng/ml are typically indicative of moderate to heavy ethanol consumption.  While PEth testing is not typically sensitive to incidental alcohol exposure such as using mouthwash or hand sanitizer, it is still possible that such exposure could affect test results.

It is important to note that test results should be interpreted in the context of all available clinical and behavioral information.  The PEth test is not intended to screen for minimal or infrequent alcohol use.  An Alcohol EtG Urine Test is more appropriate for detecting recent, less excessive alcohol consumption.   

Turnaround for this test is typically 6-10 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
