Ethanol is metabolized mainly in the liver to acetaldehyde and then to acetic acid, and its excretion is very rapid and the detection time in saliva, breath or blood is typically limited to <12 h and a few hours longer in urine, depending on the amount of alcohol ingested (Helander et al. Urine testing is highly sensitive and can detect low levels of alcohol consumption within hours or even days after ingestion. 1 In the footsteps of ethyl glucuronide. 2 g/L ethanol … Ethyl glucuronide and ethyl sulfate. # 34104) Download PDF However, there are some urine samples with much more pronounced matrix components that can interfere with the analysis of EtG and EtS in urine, even when using a fit-for-purpose solution.
