    No. Phosphatidylethanol (PEth) is detectable only following consumption of about 6-7 standard drinks within a one-week period. Some estimate higher at about 200 g of alcohol.

    At any rate PEth is not detectable following a couple of drinks and is used to assess sustained drinking rather than infrequent low level intake.

    If you don't mind, I'd love to know the type of agency offering/requiring this test.
