If you had two 8 oz beers exactly 80 hours before your EtG test will just positive for alcohol or it tell how much drank?

An EtG (ethyl glucuronide) test can detect the presence of alcohol use up to 80 hours after drinking, but it cannot determine the exact amount of alcohol consumed. EtG is a direct metabolite of alcohol, and its presence in urine indicates that alcohol has been consumed within the past few days. However, the concentration of EtG in urine does not directly correspond to the amount of alcohol consumed or the level of intoxication.

Factors such as metabolism rate, hydration level, and urine dilution can affect the concentration of EtG in urine. Therefore, EtG tests are generally used as a qualitative measure to indicate alcohol use rather than to determine the precise amount of alcohol consumed.

Please note that EtG testing cut-offs and accuracy may vary depending on the specific testing method and laboratory standards. Consult your healthcare provider or refer to the specific testing guidelines for more accurate information regarding EtG detection windows and the interpretation of results.
