Will methanol cause a false positive in an ETG urine analysis?

Question

I use a lot of methanol as a solvent at my home studio. There are times when I get light headed and have to quit for a while due to breathing the vapor. My pain specialist likes to do a monthly UA to keep his patients on the up and up and the UA he uses includes an ethyl glucuronide test for ethanol consumption. I don't drink anyway, but he discourages alcohol consumption for his patients on opioid therapy as I am. Need I be concerned?

What I am asking is will the test discriminate between methyl glucuronide and ethyl glucuronide? I thought I was being clear that I do get methanol in my system by breathing the vapor. Obviously, I do not intentionally imbibe the methanol.

no.  its highly doubtful you would have enough of it in your body for it to show up on a urine test, so you can relax.

very bad idea to use methanol unless in a VERY well ventilated room or outdoors

(Most containers warn that you MUST be outdoors when using it as a solvent)

becoming light headed is a sign the room aint well ventilated and is a symptom of methanol intoxication

Having this a number of times is a VERY bad indication

If I were you I would be FAR more worried about the ventilation and light headedness  than the test

Cos continuing as you are there is a fair to good change you will kill yourself

Of course not.  It's the metabolites that the test detects, and the only way for that to happen is if you ingested it.  And methanol would kill you BTW.
