Etg test

This post is for anyone who can help me understand the Etg test. I had about 5 shots at 9-10pm last night. I found out that I have to take an Etg urine test at 7pm tonight. So I have like 21 hours from my last drink until my test. I’m not a regular drinker but I was at a Christmas party and didn’t know I’d be testing, but I still messed up and I’m working on my sobriety.

For anyone who knows, would I fail this test? I’m only going to be drinking water and getting vitamins. I know they say it can detect up to 42-80 hours. Am I genuinely screwed?
