This flaw in EtG testing was known before it was introduced into the US market (2004) even though "Internal and external dilution of the urine are well known [most practiced] strategies among drug abusers, to try to avoid detection when being tested for illicit drug use.
One of the many reasons that EtG testing cannot be relied upon for detecting alcohol consumption and use of the test is discouraged by US Health & Human Services and is not part of any federally regulated
drug testing program." Dahl, 2011 NOTICE:
Any person or entity that is subjected to or relies on EtG testing should read this Advisory issued by the US Department of Health and Human Services, September 2006 and remains in effect as of date of this posting. Copy available here > US DHHS Advisory
