"Consumption of 20 to 33 fl oz of beer (4.2% w/v) resulted in urinary EtG concentrations of 22,000 to 67,000 ng/mL at 3 hrs. EtG can be routinely quantified in urine for about 20 hours after a single drink of an ethanol containing beverage. EtS has been routinely quantified in urine 24 hrs after a single drink of an ethanol-containing beverage. However it is reported that these compounds can be detected in urine for up to 80 hrs after heavy ethanol consumption"

Noting the quotes, where did this come from?

It was printed on my lab results from Quest Diagnostics

[DrBill100]

That is a bit disappointing. The named lab is one of the leading laboratories in the US and has no need to engage in that type of vague and ambiguous promotional narrative.

[PandaB]

I think what they wrote is commendable. The lab websites usually promote EtG as "can detect alcohol use for 80hrs" or some variation of that. Quest pretty much says what you knew, and what I now know, about EtG... 80hrs is only for heavy drinking. But I agree, there really are a lot of variables to consider in EtG testing/limits

I had 2- 6 packs of heineken and about 12 of those airplane small bottles of vodka between Friday and Saturday... I had an alcohol urine test 9-days later, would it show positive after 9-days?

No. If you survived that drinking episode the EtG wouldn't be there after 9 days.

I am a registered nurse on probation for one dui with the nursing board. If you want true results of ETG testing read this article. They could not get a positive result after 48 or 72 hours. The only positive results were before 48 hours and they did not test for diluting urine which does dramatically reduce ETG which is a water soluble protein. So if you drank Saturday and drank a substantial amount of water Sunday and Monday morning. Then testing Monday afternoon you will pass with no problem. I do know this from experience. http://alcalc.oxfordjournals.org/content/42/4/317.full

ETG testing is so flawed. Women have the hardest time with positive ETG tests and dilute urines. I am a male by the way but I do see this frequently.

Cardiac RN - I am on probation as well for a DUI (46yr. Female) so what do you mean by "women have the hardest time with positive ETG tests and dilute urines", is there something I should know? Also, how do you know what type of test they did on you (did not test for diluting urine). I appreciate your response.

[Cardiac RN]

From what I have read and seen since the 2 years I have been on probation is that women have more problems w dilute urines so they are more afraid to drink plenty of water. The reason women have more problems with dilute urine is creatine is used by muscles which put off a by product called creatnine. Creatnine is used as a marker for dilution. If you are worried about dilution you can pick up creatine powder at most health food and nutrition stores. Mix it with your water during the day and you should have a better chance of avoiding dilution.

You mentioned you have been on probation for 2 yrs (is this directly from the dui)? Also, what type of urine schedule did they put you on (random, monthly, etc.). This is my first time for random urine tests and I am not taking any chances, a drink or two, is not worth what could happen to me.

Exactly. I get tested 3x month. Don't drink. I'm not telling anyone to drink. I am just giving out info I have found to be true regarding these highly flawed ETG tests. It sucks being on 3 years probation that is far stricter then most parolees get for a one time misdemeanor DUI, but I am dealing w it. There are so many people out there that talk about these tests and have no clue what they are talking about. So I read and researched and here it is. Good luck and I recommend keeping clean and getting it over with. It goes fairly fast.

Thank you Dr Bill I find that very interesting. ETS/ETG detected for 1-2days sounds right and one of the few articles out there that appears to be based on facts not assumptions. I have read many of you posts and I really respect your medical opinion. You tell it like it is and don't just assume. There are many MD's out there on the net and if you asked them a taboo question about "slipping up and drinking the night before" Can I pass tomorrow? They directly say no its 5 days don't be a idiot and drink. Thank you for the info. I will pass any thing else I may find on the subject as well. Great article

[sonni99]

I agree with Cardiac. Every one makes mistakes and that is how we learn in life and there are people on here that are so eager to judge you and tell you what to do or "not to do". I always wonder if "those people" have gone through life not making any mistakes... I have yet to meet the "perfect human being" on earth. Thanks Dr. Bill for your knowledge and updates.

Yes it is very close, I have to wonder why you drink knowing you have to test

Please help I took 1 shot yesterday at noon. When I test today will be about 29-30 hours. I've had 2 monsters 2 redbulls ran a track 2x. Please I'm so scared! Will I pass an EtG? I'm 33/f 110 lbs

In direct response to your question, yes 500 cutoff is much better than the unofficial lab standard of 100.

However, I was basing my observation on a 500 test, one of the few naturalistic tests available. In that test involving consumption of 5 drinks (1.5 oz) none of the results were positive after 48 hours. This involved only a few individuals however. So you're still in that fringe area either way. But the higher the cutoff the less likely detection.

Each time you ask a question I am winding up on a different thread although they're all related. I don't know if it's me, you or the site?[/QUOTE]
