unlikely detected

Detailed Answer:
HI, thanks for using healthcare magic

ETG urine testing detects the break down products of alcohol use.

The ability to detect alcohol would depend on the degree of use. In persons who have a history of persistent alcohol use, it is able to detect alcohol after a longer period of time.

If there is no history of alcohol abuse, only rare intermittent use then it can usually detect alcohol up to 48 hours though some labs state that they can detect it up to 72 hours.

At the time of your test, the 72 hour part would have passed. This means that it is unlikely that they will detect it in your urine.

I hope this helps, feel free to ask any other questions
