Bac was zero at 0 at Wednesday 6 am... had 9 lite beers the day before over 8 hours. Testing is Monday at 8am... wondering if there is a chance for a positive test?
Dr Bill if your out there I think...

Hi,
Thanks again for your opinion... the Odouls was consumed on Sat and Sunday... so well before the test date... 2 on sat and 1 on Sunday... I am assuming of no significance. I realize this is a...

I stopped drinking Thursday night around 12... had maybe 7 beers... I know for a fact my bac was zero at 8 am Friday am... I will have an ETG on Wednesday at 8am... I did have three O'Douls during...

Thanks so much... I think I now have a very good understanding of the process... seems like the science doesn't square up with the lab's marketing schemes

Thanks again

So... as etoh has been eliminated (I guess that would mean your bac is zero)... just to clarify the water issue... the EtG that has been created will be then eliminated via your urine... if you...

Thanks.. you are always so informed... does drinking water days prior to a test help eliminate the EtG that has been produced since you are processing more urine? Or is it just the dilution on the...

BAC.. was measured then.. not sure actual... drinking episode was over 7 hours (if that matters)

Does the 80 hour test usually refer to the last drink or when the bac is zero?
I realize most of the studies show that the 80 hours is rarely the case... what would your guess that the EtG in the...

If a person had 6 microbrews... 14 ounces at 6% alc... if a test needed need to be run at 7pm Tuesday... bac was zero at 12 noon Saturday... 185 pounds-male... Stopped at 12 Friday night... so 91...

Does excersise or drinking water help reduce EtG levels in your urine quicker?

Dr Bill... thanks for the frucrose idea
Now using what you told me... it seems like that helps with the elimination of ethanol quicker, so EtG would be created earlier, hence it might shorten up the...

Dr Bill... I got answer back from Dr Skipper.. He said that the info on the grapefruit juice and the cp450 was most likely a mistake.. so I appreciate you working through the biology . I think he...

Hi DrBill... So,
• Substrates / Inhibitors for CYP2E1
• Cimetidine
• Disulfiram
• Propofo

These drugs inhibit the enzyme that effect the metabolism of ethanol... one is Antabuse and...

Wow. Thanks for your response... I will send a note to him as well. Unfortunately I am a bit daunted by the biology. So I assume you are saying that gfj does not affect the enzyme that could alter...

Thanks for your time... I haven't been drinking, but I start having grapefruit juice as I anticipate I am going to test. So far so good... but it really doesn't say anything because I haven't had any...

Dr Bill.. hope you found the presentation.. it clarifies that detection level just like you said-thanks
The slide refers to cyp450 enzyme... just don't know how that fits??

Any further thoughts?...

Maybe this is better... so .1mg/L is =100ng right or is it .1mg/l=1000ng? Sorry, just not sure...

This link below should work... it is the 19th slide in.. I just have not found another reference
He says greens increase it? I just don't have the bio background to understand the science

...

Thanks... so most of the studies used the 100ng level as their cutoff.. good to know
I had just seen in a presentation that grapefruit actually reduced ETG while some other foods increased it. So is...

Hi,
I am a bit confused on the actual levels that are used in EtG testing: Most european studies I have read use .1mg, but I have read a bunch of studies referring to 100NG... they don't seem to be...

Thanks so much... just one last observation:
Kaliber is reported to have .05% ABV
O'Douls is said to have .5% ABV
Are you familiar with the NA drinks and do they really cause positive ETG when a...

This is the presentation I came across... here is a paste of slide text... check the slides out
Grapefruit is shown as decreasing ETG
Things that can increase  or decrease 
EtG production...

Thanks.. I have read many of your post-you have pretty much confirm all the ETG studies
Seems like a lot "marketing" by labs to give the courts, etc.. A false sense of efficacy.
On one of Skipper's...

I am wondering about passing an ETG test... at 7pm on Monday I drank 8oz of a Kaliber Beer (non-alch)... that's it.
Test is Wednesday at 8am just over 36 hours... that's less than a gram of...
