PEthStat for Blood Alcohol – Phosphatidylethanol
The most innovative and rapid way to test for PEth.
Positive results indicate risky alcohol drinking behavior during the 2-3 weeks prior to the collection. Look Back: 2-3 weeks! According to the United State Drug Testing Laboratory,
Phosphatidylethanol (PEth) is an abnormal phospholipid formed in cell tissues following alcohol exposure. PEth in blood exists as a component of the red cell membrane1. PEth is a mid to long-term alcohol biomarker measurable after engaging in risky alcohol drinking behavior. A positive result is an indication of binge2 alcohol drinking during the 2-3 weeks prior to the collection of the blood or blood spot.
Collection is as easy as:
BloodSpot collection is the fastest, most convenient way to test for PEth. Sample amount is 5 dried blood spots on USDTL-provided filter paper when collecting from finger or 5 milliliters of blood if using standard venipuncture collection. Results are available 4-7 days after the sample is received in the laboratory. While ethyl glucuronide (EtG) is a sensitive and valuable assay for those individuals in treatment programs for alcohol abuse, recent studies have indicated that low level positive EtG results can be produced by certain agents like hand sanitizers and mouth wash.
The PEthStat assay helps to discriminate between incidental exposure and intentional alcohol ingestion. The volume of alcohol required to trigger a positive PEth result is far above the level commonly attained by incidental exposure. Studies have shown PEth levels are not influenced by age, gender, or disease, unlike most indirect alcohol biomarkers.”
