If the beer had 4.2 % alcohol and drank it from 830-1030 and took a EtG urine test 39 hours later what is the dectection time frame? I am a 33 year old female and urinate every 2-3 hours even when I am sleeping.

Kris,

Assuming that you are in good health, the amount of EtG synthesized from one beer (12 fl oz, ca 5% abv) should be undetectable beyond 24 hours.

The foregoing is independent of gender, age, weight or urinary frequency within normal range.

Thanks dr bill your input is always welcome. The beer was 24 oz in two hours my problem is frequent urination. I urinated like 6 times in that two hour time frame, also 4 time that night. My bladder likes to empty itself every 3 to 4 hours. The beer consumption was a total of 4.2% volume.
