Duration: | 8 days |
Indication/Significance: |
If the screening result is above the cut-off, a confirmatory test will be carried out. |
Interpretation: |
When abstaining from more… When abstaining from alcohol, ethyl glucuronide is neither detectable in urine nor in serum. EtG can be proven after one-time-only consumption of an amount of alcohol from approx. 10 g on. Compared to ethanol, ethyl glucuronide is detectable in urine for a longer period (ethanol: 12 - 24 h, EtG: 1 - several days; in each case dependent on the dose of ethanol). In this way, the prohibited alcohol consumption during the weekend holiday outside the rehabilitation centre can be proved or ruled out more reliably by means of the presence of EtG in urine than by means of ethanol in urine. |
