I have to take a urine test in two days. Today I wiped down a work table with rubbing alcohol to clean it. Can this show up on test?

No. Rubbing alcohol is isopropyl alcohol and urine tests screen for ethanol. You're wise to ask however as some ethanol based hand cleaners are known to show up on the more sophisticated tests. You should have no problem.

Thanks DrBill, I was wondering what the answer might be:)

Interesting how some of the tests may or may not show positives.. guess it goes to show you,you can make a test,plan for the outcome, but never really know.

Urinalyses are notoriously unreliable.

EtG screening is largely unregulated except for the federally mandated tests. Exposure to environmental ethanol can produce detectable EtG in life-long total abstainers. Yet many, if not most, laboratories offer a cut-off of 100. (Federal tests establish a cut-off of 1000.) 40% of all positive results derived by EtG fall in the range of 100-250. With full knowledge of this, and the need for a uniform cut-off, laboratories and EtG proponents offer up a way to validate low level findings by contract.

If you'd like to read up on this Greg Skipper, MD, who introduced the science in the US (2004) has a website. I consider this the most authoritative since the founder and leading proponent provided the info.
