| Ok..I'm not an expert and have absolutely no experience with this whatsoever.
But I looked up the test because I'd never heard of something that could detect alcohol up to 80 hours after the fact. The sites seemed to confirm what you said however, so using basic logic..
It takes one hour for the body to metabolize one drink. You said you had four. Then you said your test was on the 5th-three days later. Even if you took the test at midnight, which would actually be the sixth, that is still only 72 hours. This test claims it can detect alchol up to 80 hours after the fact, and you have to consider that even if you drank your last drink at ten pm, it would still be in your system until eleven.
I'm not sure how much sense that makes, but to my logic, you are likely to be caught. Again, I don't claim to have any knowledge or expertise on this matter, and you should check my calculations because math is not my strong suit. So...
Edit..Yep, my math is wrong. Friday, Saturday, Sunday..that's 72 hours. Depending when you took it Monday, it might've cleared the 80 hour mark. However, it does take your body an hour to process one drink, so I'm not sure if that sets back your stopping point to when the last glass was metabolized. |
