Ethyl glucuronide (EtG) in urine is considered a marker of alcohol consumption. We present a case of a false-positive immunological EtG screening result due to excessive isopropyl glucuronide excretion in urine of an alcohol-dependent patient with a

Background Ethyl glucuronide (EtG) in urine is considered a marker of recent alcohol consumption. Using immunoassays for EtG screening without confirmatory analysis bears a risk of getting false-positives as shown for trichloroethyl glucuronide from
