Phosphatidylethanol (PEth) Alcohol Test

PEth, Ethyl Alcohol Biomarker


Specimen Type: Blood

Description:

Phosphatidylethanol (PEth) Alcohol Test

The PEth Blood test measures levels of phosphatidylethanol, an alcohol-specific biomarker, in the blood.  PEth is a phospholipid which is formed in the presence of ethanol and bonds to the membrane of red blood cells. The more a person drinks, the more PEth will be formed.  PEth blood testing is used to detect prolonged or heavy "binge" alcohol consumption.  The typical detection period for PEth is 2-3 weeks but it 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.  Because PEth requires the presence of Ethanol to form it is considered more sensitive and specific than other forms of alcohol testing.  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.  A PEth test cannot indicate if a person is intoxicated at the time the test is taken.  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.

Requirements:

Customers testing in the state of California should call their selected lab to verify that they can do specimen collections for a chain of custody blood drug test.
