Decline of phosphatidylethanol (B‐PEth) during abstinence in patients with alcohol use disorder undergoing withdrawal treatment, and the correlation of B‐PEth with self‐reported alcohol intake
Elimination of phosphatidylethanol in blood (B-Peth) follows first-order kinetics, with homologue 16:0/18:1 exhibiting a longer half-life than 16:0/18:2. The rate of decline is influenced by the week of alcohol abstinence and B-PEth levels are detectable even in the fourth week of abstinence. The strongest correlation between B-PEth and self-reported alcohol consumption is at two weeks prior to abstinence.
