Probation sprung a surprise EtG test on me. They took my urine sample at 5pm Tuesday. The preceding Thursday I had 4 beers. Friday I had 10 beers over 6-7 hours. Saturday I had one glass of champagne and 3 beers over a 3.5 hour period. I stopped drinking on Saturday night before 9pm. I am a 25 year old male, 5'10" tall and 170 lbs. If it was 68 hours between my last drink and the time that I provided the sample, is there any possible way that I could have passed my test?
