What is the clearance time at a 500ng cutoff for 4.5 to 5 drinks and is it from the time of last drink or time of BAC 0 ? Does anything speed it up like sleeping less to have a higher "awake" metabolism longer, or eat certain foods? Or eat a lot to keep the liver active? Any ideas?

Dr Bill Can you help me?

I had approx 22 light beers on thur and one shot of vodka started drinking around 7pm and stopped about 2am which would have been fri morning technically. I am a male 27 years old 185 pounds and 5ft6in tall. I took a test on moday at 2pm. I haven't drank in almost a year before this episode. It was approx 84 hours since I had my last drink. I drank approx 2 gallons of water each day following my drinking episode up to Monday when I had to test. What are my odds?

Your chances of passing are very good but not guaranteed. EtG testing seldom detects even heavy drinking past the 78-80 hour range. Some tests conducted in detox facilities have detected up to 102 hours (Borucki, 2005) but that is very rare.

That is a huge amount of alcohol for a single session! Not particularly relevant to elimination... just an observation.

Thank you for your quick response I will reply when the results are in. Thanks again

Do you think the water consumption that I had will help and with the 500 cutoff instead of 100 isn't that a big difference just wanting to get all the details

Please stop, you are breaking the rules spamming this site with the same question over and over. I have deleted 3 or 4 of them at this point,

Keep all of your questions about the same subject on this one thread.

It is widely published and established years ago that "... it is possible to decrease the urinary concentration of EtG to fall below the [level of detection] of the analytic method, simply by drinking moderate to large amounts of water or any other fluid prior to voiding."

This flaw in EtG testing receives no mention in the advertising of the commercial testing industry directed to those that pay for and depend on the results. That's understandable as water-loading is the most common strategy among drug abusers, to try to avoid detection when being tested for illicit drug use of any type.

If this phenomenon was understood in the marketplace who would use the test?

Most of the literature has used the 100ng cutoff. The difference in detection time is estimated to be about 10%. I suspect that the difference is at least twice that but is yet to be established.

I apologize I am new to this site I understand your frustration.

Had a test the next day which was tue which put me at 106 hours and I was clear on this test but still haven't got results of test taken on Monday. You still think I have a chance on that test Dr bill?

You had an EtG test on 2 consecutive days? Am I understanding that correctly?

That would be very unusual. Are you sure they aren't doing Urine alcohol?

Sounds like they are testing Urine alcohol (EtOH)?

It is random could be 3 days in a row could be a week in beetween so yes two days in a row and I am sure it is an EtG with a 500ng cutoff.

HOPE - Just curious to see if you received your results from Monday's test.

I should have the results tomorrow I am not too worried about it. I have passed them in 48 hours but drank less. What is your situation maybe I can shed some light.

Dr bill,
I should have gotten a call yesterday if I was over the limit but I'm still nervous. Just a few more questions if you don't mind. I notice in one of your posts you say that even heavy drinking episodes are usually negative in the 70 hour range is this still what u believe? Also don't you think after 84 hours from last drink I would at least be under the 500 ng cutoff? I have been reading a lot of the articles you ref in your posts and I have to say I can't believe I would be over the 500 especially with the amount of water I consumed the previous 3 days before testing I would say on average 2 to 3 gallons a day. Plus I know I had a 0 EtG reading on the test I took after the initial test which was about 24 hours after my 84 hour test. Dr bill I value your opinion on this more than you know and I want to say thank you again for your knowledge and answering my questions.

Everything is in your favor. 500 cutoff, water consumption, passed the following day, and you are in the time range when very few people have EtG.

However, there is no certainty with EtG testing.

Does anyone know if the testing lab is required to tell you what type of test that are doing? As for the ETG, I have been reading that they should be advising you not to use certain items (mouthwash, hygiene items, etc.) before testing, is this true? I am just baffled that a justice court system would use ETG tests when there is so much uncertainty behind the results and that an individual can challenge the result and in essence, cost the court system more money to re-test or fight the challenge. Your opinion?

There is a recent ruling requiring that laboratories provide results of drug testing to the subject tested, don't have the requirement in hand as yet. As a matter of informed consent you should have been provided with a list of alcohol containing products to avoid. The recommended guidelines can be found here:

Ethylglucuronide (EtG) and Ethylsulfate (EtS) - EtG and EtS Testing (http://etg.weebly.com/)

Dr Bill,
Got the results and I was at a 0 EtG reading from my test on Monday. Thanks a lot for your input it is greatly respected and appreciated.

Why did it take so long to get your results? Just curious...

It had to be sent off to a lab far away
