I am a male, 180 pounds and about 6 ft tall. I drank approximately 9 beers Friday night over a span of about 3 hours. I've drank a moderate amount of water and have an above average metabolism. I've read plenty of other posts and am still worried. I just need some closure, any input would be greatly appreciated.

Using your figures and assuming 70 hours was from time of last drink your BAC would have been in the vicinity of .13 at that point. You would have been creating EtG for at least the next 6-1/2 hours. That is figuring your EtOH metabolism at .02 per hour (high). From BAC=0 that would leave about 63 hours for EtG elimination.

Helander found the median clearance time to be 66 hours (range 30-110 hrs) from BAC=0. These were averages based on 32 individuals in a detox unit (variable amounts consumed-therefore imprecise). (see Helander, et al, 2009 (http://www.ncbi.nlm.nih.gov/pubmed/18971292))

Nevertheless, you are in a gray area. There is no precise answer to consumption above .08 BAC. Never dose measured. Overall, 13 isn't particularly high BAC. The odds are probably in your favor, but not by much.

Thanks for the reply. I stopped drinking at midnight on Friday, so that actually leaves me with about 84 hours because I just took the test at one. How much would that improve my chances?

Immensely. Time is the most significant factor. Very seldom does even long term heavy drinking create EtG that is detectable above 78 hours.

Please let us know when you get the results.

Sweet I feel much better you seen to know your stuff very well and for that I thank you!
