Greetings DrBill100. I have appreciated your advice given to all. If my EtG test urine sample was taken 113 hours after my last drink will I pass the test? Also, is the sample affected by temperature changes when in transit?

Regardless of amount consumed you should have no EtG present at 113 hours post-consumption.

EtG is definitely affected by temperature. Unstable in sample post-collection.

Thank you Dr. Bill. My test results came back negative although they tried their best for a positive. All those that read these posts need to reply as to their results and help the masses. You are the SME on EtG. Take care my friend.
