You regularly consume alcohol yet the test(s) failed to detect. A false negative result.
Not unusual. Points to one of the many problems with the EtG testing procedures and/or the manner in which it is administered. Overalll the value of the test as it is currently used commercially falls to the downside of questionable.
Want a quick answer? Then, Yes. Drink a lot of water and the EtG will probably go away. Water dilutes urinary EtG and EtS and may very well allow you to pass this or the next urinalysis. Then what?
Urine dilution, as you (and I) describe, is, after all, the most widely used means of avoiding detection in all types of drug testing. With most substances it doesn't work. But alcohol is miscible in water and it's metabolites are water soluble. The fact that EtG is reduced by diuresis is established and extensively published. (as ex: Goll (http://www.ncbi.nlm.nih.gov/pubmed/12166812?dopt=Abstract) and Dahl (http:////www.scopus.com/record/display.url?eid=2-s2.0-0036014541&origin=inward&txGid=pXQiBfKJ-BNcxR-wUKjn-cm%3a5))
Nothing new here! This EtG-test-vulnerability/deficiency was known well before it was introduced in the US in 2003.
Notwithstanding, this test was presented and promoted by members of the medical and scientific community as a superior method for detecting surreptitious alcohol consumption. But we know better... don't we?. No such capability... the test detects minute molecules of EtG indiscriminately. Those molecules may derive from consumed alcohol, grandma's cookies, brake fluid or mouthwash.
On your own and using a time-worn technique you have defeated the most advanced and sophistkcated scientific instrumentality... by drinking water? Unfortunately for us all, you're not unique, it's done thousands of times each day in the US.
On the other side of this issue are the thousands of people that, each day, return a false positive on the test due to hair care, food, or other incidental exposure. Dissimilar from your intent they are compliant but lose their job, driving privilege, professional licencse, custody of children or freedom as a consequence of following the rules.
So the test fails to detect those that do consume alcohol (you) and entraps those who do not... and it's the most widely used method in the US?
You have skated through a very big hole in the wall... You and thousands of others... can't blame you... can't support you... but damn the inequity of the process.
