How do I test for wood alchol

Hi Folks!!
I am going to do a complete over haul. I've done the bowel, the parasite, the liver flushes, kidney cleanse, but I would like to stop consuming wood alchol. Does anyone know how to test for it??

In the "Cure for All Disease" Dr. Clark sayes to test for it, but I didn't see an explantion of how to do it. I could have missed it, but I'm lost on this.

If anyone can help me on this, it would be greatly appreciated.

Thanks, Kya
