Dr Bill, I`m a 225 lb man. I drank on a Fri night till midnight, about 8 drinks and had to take an ETG test at 3 pm the following Monday 63 hours later. What are my chances of testing positive. Thanks Mike

By the way the court uses a 500 ml cut off

Will these help you?

Your question would be better answered with a little more details, so I have simply posted what a few other threads have had for answers.Hope they help.

Your question is unanswerable without the amount of alcohol consumed.

With 8 drinks, last at midnight, you're running damn close. The problem you encounter is that EtG is produced during the metabolism of the drinks which continues after you cease consumption. So let's say that you still had 3-4 drinks still coursing through your system. That could take 4.5-6 hours and EtG is still being produced. So you could be down to 57 hours clearance time or even less due to reduced metabolic rate while sleeping.

However, there is extreme variation between individuals in EtG production. Additionally, I'm assuming you have some history in drinking and that usually accelerates ethanol metabolism by about 19-23% (once again average). So any way you look at it you're on the cusp.

Best of luck.

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

Didn`t know

Dr Bill, I`m a 225 lb man. I drank on a Fri night till midnight, about 8 drinks and had to take an ETG test at 3 pm the following Monday 63 hours later. What are my chances of testing positive. The court uses a 500 nl cut off-wouldnt that increase my chances?

Do you know if this is an on-site test, as in a dip stick, or cup? Those are available now for EtG and are less precise than Gas Chromatography.

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?

<threads merged>

I don`t know how they process the test. The different threads are my fault. I`m new to the site still finding my way. Do you know of any organisations that are fighting the use of pseudo science by the courts?

"Do you know of any organisations that are fighting the use of psuedo science by the courts?"

There are several organizations combating the lack of uniformity in testing as well as interpretation of low level returns. Most are in the medical field. I can't find my list, which is a little dated anyway. Suggest you search "EtG false positive" and you'll probably be surprised at the number. There are, or were, lawsuits pending in 4 or 5 states, and a SAMHSA Advisory recommending limits on the use of the test is still in effect and a must read. (see Advisory, Oct 2006 (http://kap.samhsa.gov/products/manuals/advisory/pdfs/0609_biomarkers.pdf))

Likewise, here is a link to a 2008 lawsuit available on line that points out the lack of forensic value and also contains the testimony of Dr. Greg Skipper, who introduced the test in the US. (see Ohio case (http://oh.findacase.com/research/wfrmDocViewer.aspx/xq/fac./OH/2008/20080613_0005058.OH.htm/qx))

I will be doing an experiment. Im going to drink 3 beers on Friday night, stopping at midnight. Im then going to have a normal weekend i.e. no excessive exercise or massive amounts of water drinking. Im going to self pay for an ETG test at noon on Monday (60 hrs). The cut off will be 100ug, I'll let you guys know the results. Im basing this on the research from http://alcalc.oxfordjournals.org/content/44/1/55.full.pdf+html. I officially sign a contract next week and am looking to test the true accuracy of the EtG test.

The test you cite, like most of the research, deals with heavy consumption. To assist you in your experiment you may also want to review Wojcik & Hawthorne (http://alcalc.oxfordjournals.org/content/42/4/317.full#T1) as well as Borucki, 2005 (not sure if this is available on-line). Wojcik (2007) deals with lower levels of consumption, in a naturalistic setting and using an independent testing lab. Quite similar to what you are attempting to do. Hope this helps and anxious to hear your results.

Thanks dr.bill, I never saw the Wojcik article. The reason I'm doing this is because I want to verify the research on myself, cause after all the excretion of MY EtG is what's going to be tested for in the future.

For those people that are thinking, "if you arent supposed to drink, then just dont drink"... im a social drinker. I drink MAYBE once every 2 weeks in social settings, and even then its 1-2 beers. Im going to test with 3 just to be 100% sure that when I drink the 1-2 in the future, I will be OK. If I can pass with 3, there will be no doubt I can pass with 1-2. Im being monitored because of some mistakes by others in my workplace... which I don't think that is fair at all. I should have results at the end of next week (oct 22ish), which will be reported here.

I submitted my urine sample today. I drank 4 beers over the course of 4 hours on Friday night, and stopped at 12:30am Saturday. I submitted at urine sample at 1:30pm Monday. This is 61 hours. I did not exercise or drink more fluid than usual. I did not consume any alcohol after 12:30am Saturday.

Based on the research Ive found, I anticipate my test to be negative for ETG. The cutoff the lab is using is 100ng/ml (50ng/ml for EtS). I am a healthy male in my late 20s and in relatively good shape. If this test is indeed negative, I might set up another test at around the 24hr mark.

I agree that this test should be negative. I'd be surprised if it were not. However, 4 or even three drinks at 24 hr. will in all likelihood be positive.

Also you should adjust the time interval because even after you consume the last drink of alcohol EtG is still being generated. EtG (and EtS) begins descending only upon completion of the ethanol metabolism. "0" BAC.

A further complicating factor is that your personal metabolism will vary from time to time, dependent on mood, food and other variables. Presumably, those factors would also cause EtG production to be variable, although there are no studies to support that assumption.

I got my test results back. After drinking 4 beers in 4 hrs on a Friday night (stopped at 12:30am sat), I tested negative for ETG and ETS around 60 hrs later (1pm monday). During the 60 hrs, I did not do anything special. I didn't run 10 miles, I didn't drink 10 gallons of water, however I did avoid alcohol.

All I wanted to accomplish was to see if my social drinking would be detectable in an abstinance program. Now I have confirmatory results for my body. The test result paper sent to physicians had information about ETG different than their website, I'll type it here when I get home.

"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

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.

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.

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.

Cardiac

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

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
