Dr. Bill, can you please give me some info? I had 3 beers from 11:30 - 2, then white wine through out the day sat. Last drink of wine approx 10:30 pm. I'm 5' 7'' 130ibs. I was called to do a random BA the next day Sunday. I blew .011 at 1:30 pm, then waited15 min and blew .00. I am now being called in to do an EtG by 7pm tonight - Tues. I have drank nothing other than water and detox tea all day Monday and will today. What are my chances of passing an EtG? The cutoff looks to be 100. I appreciate all your help in advance. I'm really scared. Thanks

No Dr Bill...


So this happened Saturday and you are being tested tonight? You could fail... on the other hand, you could pass. It's all very close and the only way to know for sure is when you hear the results.

As a side note... you and everyone else that posts about taking an EtG test... you're always scared or in a panic over the possibility of failing. Why not just not take the chance and don't drink at all? It seems silly to me that you're not supposed to drink but you do, then you panic. I'll never understand it.

Also, I was wondering. Does the EtG test start from the last drink I consumed Sat night or from the .011 I blew on Sunday? Thanks a ton. :/

ETG will be from the last drink... blowing into a breathalyzer has nothing to do with ETG levels.

Thank you for your input. I'm calculating 68 hours from last drink.. What's the experience on passing in this time?

I'm in a complete whirlwind. Can anyone with these expertise give me any input (possibility of passing after 65 hours from last drink. I've drunk a lot of water with frequent urination?) Greatly appreciated!

Nobody is going to be able to give you anything definite on this. The time is too close. If you were around 40 hours, I could say you would fail... if you were around 80, I could say you would pass... you're in between so who knows for sure? It could go either way.

I can say this though, if you drink too much water, you will fail for dilution.

But really though... the test is tonight... pass or fail has pretty much already been determined by the time you get there so why panic? What happens, happens.
