DrBill -

I read an interesting article on the sensitivity of EtG tests, but the article was published in 2007 and apparently the study was conducted in 2005 or 2006. Are you aware of how these tests have changed since then? The claim is that the EtG test will confirm within an 80 hour window... however I have seen information that this window only catches the most extreme cases and likely someone with a slow metabolism.

Generally, for the EtG test to be most effective it would have to be conducted every 24 hours or within about a 48 hour window. Do you have any further insight?
