    ETG Enzyme Levels
    Hi, does anyone know how much alcohol is needed to be consumed to trigger the enzyme? I wondered if you just had a few sips over a whole day (less than a glass of wine) would this trigger a positive result in an ETG test? Thanks.

    Even small trace amounts of alcohol will produce EtG/EtS and will spike above the level of detection on many tests. However, the peak EtG rapidly declines and will not register on a test after several hours. The main problem is timing.

    Using your circumstance, 1 glass of wine (14g abs. alc.) could be detectable beginning about 2-5 hours after consumption but would be eliminated from your system in 13-21 hours. There is an interval in there when you could register a positive, especially at 100 ng cutoff, but it is only for a few hours.

    Thierauf, 2009 Urine tested positive for ethyl glucuronide after trace amounts of ethanol. Addiction, Dec;104(12):2007-12.
