A friend drank 16 beers, takeslasics daily and wants to know if he will pass ETG toda

By the way, Drank Thursday night until around 2 am. Test tonight Tuesday at 7:30 pm.

Estimating consumption rate of 2 drinks per hour would result in a BAC at time of last drink right at .24 (est weight at 160).

Time from last drink to test 89 hours - time of alcohol metabolism 16 hours = 73 hr for EtG elimination.

On average, that is not enough time.

If the Lasix is related to liver or kidney disorder then detection becomes far more likely.

From BAC=0, 78 hours would be the likely detection window for heavy and prolonged drinking. The other end of the range would be as little as 40 hours for clearance.

You throw me off with the statement of today/Tuesday. If the test is tomorrow, Tuesday, then the odds improve significantly.

EtG elimination at high levels of consumption is ill-defined. There are no studies that specifically specify quantity at those levels. All that is available are BAC levels from which quantity must be extrapolated. The higher the level of consumption the greater the margin of error in predicting the results.

Please let us know the results.

Okay more specific. Lasix is to compliment Adipex for weight loss? Wants to lose 75 pounds and has been taking it every morning for 6 weeks. Both of them. No known liver or kidney problems.
And yes the test is Tuesday but 7:30am and he quit drinking at 2am Friday (so he drank Thursday early evening into Friday am)
Does ths change your predictions?

Time is the secret to this test. That puts the time at 77.5 hours whereas I projected 78 was needed.

The fact that he has been taking a diuretic is in all likelihood helpful to EtG elimination. Still too close to call but I would say the odds are in favor of passing at 100 ng cutoff. If the cutoff is 500 he will probably pass.

As example, a study of 32 detox patients with BACs ranging from .10 to .34 were tested from BAC=0 and the median clearance time was 66 hours, with a range from 30 to 110 hours (cutoff 500). See Helander 2009

Please let us know the results of the test.

Tested Tuesday morning at 7:15am. What do you think based on that time? I will repost with result, his last test took 1 week to get results, but they were neg. he has tested positive before and apparently they came back much quicker. Not sure if pos. result had any affect on reply time, probably in a hurry to violate him. Got 30 days and still can't quit drinking (2nd offense DUI and then violatd terms). Comes to meetings every day, just having a really hard time. I am doing what I can, but not much one can do when they wait until they are drunk to pick up that phone.

A couple of hours is inconsequential. Chronic heavy drinkers often metabolize alcohol at twice the rate of social drinkers, approaching .03 per hr.

But in the case of your friend it is either this test or the next. Even totally abstinent individuals fail at a rate of about 8%. Anyone subjected to EtG testing is in peril of a positive, false or legitimate. When one begins to push the boundaries of EtG testing, or time their drinking, it is inevitable that they will be detected.

How old is your friend?

I would say 38-40. Were not tight, just members of AA together. His situation has landed him broke and living with another guy in the program. They have no internet, thats why I'm the middle man.

I have done a lot of research on the subject since I also test. I however am more interested in WHY we produce ETG's. Not how to get rid of them, as I have been able to stay sober since beginning the ETG testing. I did relapse in AA, resulting in a DUI (1st offense) however have remained sober since. I would like to know why they are produced, how they help the body or if in fact they hurt the body the whole time they are hanging around?

Also, people mention false positives a lot, however there is a test that they can do that can confirm if the ETG detected was actually caused from alcohol. I had a false positive, and was adimate I was NOT drinking, since I was NOT!!! The 80 hour test is an umbrella test, as it was explained to me, hence the high rate of false positives. They resubmitted the sample to the lab and they were able to rule out alcohol as the cause. However, I do not know what the cause was. I had surgery about 3 or 4 days prior to that test and under-went anesthia, pain pills, pain shots, etc... It is my thought that the combo just stressed my liver, causing it to over-work. I was NOT however drinking, and was ultimately able to scientifically prove it.

The source of EtG cannot be determined. If on getting a false positive your sample was re-tested, the initial result came from an immunoassay (screening) and on re-test they used the more precise LC/MS/MS (confirmation). The confirmation should have been conducted following the initial results but more and more labs are simply returning the results of the screen and performing confirmation only by request.

EtG is the same whether deriving from grandma's fruit cake or a shot of Seagrams. One of the many problems with the concept of the test. Here is a good starting point if you're interested in learning more about the test: Ethylglucuronide

I'll check it out. I WILL also post test result when he let's us know. Hardly anyone in these panic threads comes back and posts results. If he disappears for 90 days I will assume it was positive, lol. Well, not really funny...cunning, powerful, baffling, AND patient!!!
