“The result provides a detection period of up to 3-4 weeks. Ideally combined with Hair or Nail testing . details behind peth testing Phosphatidylethanol testing , known as PEth testing , is a highly reliable blood test allowing the detection of chronic excessive alcohol abuse over the previous 3-4 weeks.” Probably so. Phosphatidylethanol (PEth) has been investigated for a number of years as a biomarker of alcohol consumption (1). EtG proponents recommend it as a complementary test (3, 4). PEth is a blood test and is present only following heavy or frequent consumption of alcohol, 7 drinks or more within a 7 day period according to most estimates. Our Peth Alcohol Test (3 week look back) looks for direct biomarkers of alcohol that remain in the blood stream for up to 3 weeks after consumption.

PEth production begins as soon as ethanol is consumed and peaks within 8 h after alcohol ingestion. Drinking experiments show that PEth can be detected in blood after 1–2 hours and for up to 12 days after a single drinking episode. In addition, daily alcohol consumption of more than 60 g ethanol can clearly be distinguished from lower alcohol consumption.

What is the detection time for drugs in urine? Of course, for the remaining 10-15%, the steroid detection times can become beyond important; after all, a failed test can result in the end of your sporting pursuit. With this in mind, we want to look at the steroid detection times, but before we dive into the actual times we want to look at all the info you need to know.

PEth levels decreased statistically significantly during alcohol withdrawal (p=0.002). PEth levels of the nondrinkers and social drinkers did not differ statistically significantly (p=1.000). The area under the curve (AUC) for PEth measured by ELISA was statistically signiﬁcantly higher than 0.5 (AUC=0.691, p=0.024), but PEth had

The Peth test is designed to detect heavy drinking up to approximately 2-4 weeks prior to collection. This is because PEth has an average half-life is 4.5 days. This means that every 4.5 days the level of Peth is cut in half. The accepted detection period for PEth testing is up to three weeks however the (greater the exposure) larger the binge session(s) the longer the period of detection. Phosphatidylethanol (PEth) has recently gained interest as a highly sensitive and specific blood marker of alcohol consumption. This direct marker enables the discrimination of heavy vs. occasional drinkers and to monitor complete abstinence within a time window of 2 to 3 weeks.
