This is timely because I just had a positive Etg on Aug 20, 2005 and I have not consumed alcohol of any kind in over 11 mos. I think I pinned it downed to a dipping sauce at an Italian Restuarant that had Balsamic Vinegar in it. You see Balsamic is aged in wine casks and so theoretically may contain trace amounts of alcohol. That's the only thing different that I have done. I have had two tests since then but haven't got the results as of yet. As far as I can tell there has only been one valid clinical study on ETG testing and it was done in Sweeden. In that case the people who had positive etgs all admitted to having used alcohol. There was no control group used so the study is far from meeting the criteria to make it "the Gold Standard" for testing. This really doesn't matter to the board though. They will violate you for a low creatinine as well even if the specific gravity and serum osmolarity of the urine is within normal range. So far here is a list of things that according to "Urban Legend" cause positive ETG.
Alcohol (of course)
waterless hand soap.
Any beauty product that contains SD Alcohol 40
extra sour dough bread
Any and all "fake" Alcohol such as O'doull's, Near beer, and Fre' wine products.
I am looking for additions to this list so if you have heard of anything that might be included. When I am done with my Diversion I am planning to persue a Master's degree in addiction treatment and want to conduct a real "Evidence Based" Clinical study of the efficacy of this test. Until then we just all have to be really careful about what we eat and drink. Though my diet has become very boring as of late I have a policy that when in doubt as to the ingredients do eat or drink it. Rememeber that diversion is not your recovery and that "this too shall pass" I'll let you know how these last two tests turned out.
