I drank a bottle of red wine Friday night. Last drink was 10pm. I am 140 female that drinks about a gallon of water a day. Based on that will I pass a EtG test with a 500 cut off level at 8am on Monday morning?

Probably so, assuming the bottle was standard size (25 fl oz) containing 5 standard drinks (US). EtG/EtS could still be detectable at that time line (based on 100 ng cutoff) but unlikely. Based on 500 cutoff detection is less likely but still possible.

Please let us know the results.
