I know there are many variables concerning EtG elimination, but would it be safe to say that, no matter the quantity consumed, all EtG would be gone after 100 hours after BAC reaches zero?

Thank You

EtG is seldom detected at 100 hours even in heavy consumption episodes. After reaching BAC=0? None.

Is there a point beyond which EtG cannot be detected regardless of amount of EtOH consumed? No.

After BAC=0? No.

Your question assumes scientific constants; 1) rate of EtG production and 2) rate of EtG elimination. Both unknown.

Thanks Dr. Bill. Please let me ask my question in a clearer way. One bottle of wine on Monday, two on Tuesday. I have an EtG test Wed. the 18th. I estimated BAC reaching zero by noon Thursday, leaving about 144 hours to test. I used the 100 hour question because I have read some of your replies to people and assumed that after 100 hours one would e pretty safe. Your opinion in this case please? Thank you in advance.

Accepting your 144 hour figure, then cutting it in half, your drinking is unlikely to be detected.

Is 100 hours (after BAC=0) a safe interval regardless of amount consumed? I believe it is. To my knowledge there are no tests at or near that level.
