Integrated internal standard volumetric dried blood microsampling for the quantification of phosphatidylethanol 16:0/18:1

Phosphatidylethanol 16:0/18:1 (PEth) is a direct biomarker of alcohol consumption, formed in red blood cell membrane in the presence of ethanol. Concentrations of 20 ng/mL and 200 ng/mL have been proposed as cut-offs to distinguish abstinence or low alcohol consumption from moder...
