peth testing (phosphatidylethanol)
WHAT IS PETH TESTING?
Phosphatidylethanol (PEth) is an abnormal phospholipid formed in cell tissues following intentional alcohol exposure. PEth in blood exists as a component of the red cell membrane and is a mid to long-term alcohol bio-marker measurable after engaging in risky alcohol drinking behavior. A positive PEth result is an indication of intentional alcohol drinking during the 2-4 weeks prior to the collection of the blood.
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. In contrast, 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, therefore, topical exposure to skin from such products as hand sanitizer, gasoline, or isopropyl alcohol cannot produce a positive PEth result.
PEth testing can be completed in our office locally in Greenwood Village, CO. Walk in's welcome. No appointment necessary. If outside the Denver Metro area, please contact us an we can arrange for an alternate collection site.
