If I was a . 10 at 2 AM--does anyone know what I might have been around 7 AM? I drank coffee/lots of water before 7 AM..

With a BAC .10 at 2am by 7am it would have been in a range from .01-.035. Average would be .025

Could that range be... exposure to alcohol? Or eating spicy food before hand or something..

I've blown before like a .051... but then the device went down to ZERO 5 minutes later when I took a retest awhile back. But imw ondering if I could say it was accidental exposure.

If it was a matter of the machine it is quite possible to challenge. But the actual reading is unknown. Given the amount that you drank and the time interval it's possible that it was below .02. If there is a brand and model number I can check the range of the analyzer. But...

The UA that you took almost has to be for EtG and you will be in high numbers unless it is dilute and untestable.

Accidental exposure wouldn't apply to breathalyzers.

I have the brand and you need a model number? Im pretty sure the UA I took probably was a ETG but I drank literally 10 big glasses of water before the test. Well then how could I have blown in the past and not have drank anything? Because in the passed I have blown numbers... then the device goes off again and I blow zero. They've asked me if I have brushed my teeth or anything before hand and I've said no because I didn't but it showed I blew numbers... which that machine is messed up I've always thought it was. So.. there is nothing I can say why it was maybe high other then the machine was maybe goofed up again? Thank you so much for your in put.

Does that absolutley mean that I would have drank the night before if I did blow something.. Because again I have blown before numbers and if I didn't hear the re-test go on, they would have thought I drank and I would have had to come down to take a UA(but I've always taken the re-test because I've known it would be zero)

First, I'm just addressing a group of machines, breathalyzers. There are many things that can cause them to provide false alarms and each machine will have a sensitivity and should show a range of false positives/negatives. That information is required for certification. The sheet on the device may even provide info on the process of test-retest.

The group that understands the flaws of these devices best is DWI lawyers.

In addition, I bet that they do not rely on the breath reading. That is why that required the follow-up UA. If that is clear or untestable they probably have no more than suspicion. If that comes back positive then it will be the lab test that is relied on and not the machine. Don't you think?

Yes, but I hope I diluted it because they have PROOF I've been sober for basically 80 days. If I did blow like a . 02 or somewhere around there, they can still trace... alochol in my system 15 hours later? Im sure they can but I know I was literally a little bit "buzzed" not "drunk" what so ever. I hope I diluted it though..

& I am sure if I blew "high" or not really low(which I'm hoping I did blow low(but it wasn't a zero clearly)) they maybe did think the machine messed up.. but yah I was hoping I just flushed it all out.

Sorry one last question-is it possible to dilute ETG testing?

There will be no alcohol in your system at that time. That was gone by about 9am. The only thing they can find is EtG, that's something created as you metabolize the alcohol.

If your urine is too dilute to test then they won't find anything. If it's testable then they can easily compare EtG to creatinine which overcomes dilution. If they don't use that system then EtG is vulnerable to dilution. It really comes down to the test in this case.

" If it's testable then they can easily compare EtG to creatinine which overcomes dilution. If they don't use that system then EtG is vulnerable to dilution. "---and that would only happen if I didn't dilute it correct?

Sorry--so there are a few types of ETG tests.. and on ONE certain test are you saying that they can see if you were drinking even if it was diluted? Maybe I am just confused. Well I'll keep you posted on what happens... if anything happens..

I guess what I should be asking is.. is hard to dilute ETG test? Meaning having probably 2-3 liters of water before the test? Plus lots of vitamins.

Thank you your going to heaven for all the help you've been!
