Determine the toilet wall where the back of the toilet tank will be, measure it from end to end and spray a dot of marking paint on the floor at the center point. Alternatively, spray a dot that represents the location of the toilet. Take the cover off of the toilet tank, and lay the toilet on its side to access the underside of the base. Measure from the back edge of the base to the center of the closet hole, or drain hole. Note if the measurement is 10 inches or 12 inches. Measure straight out from the face of the wall at the dot for the center point, and spray a dot on the floor that represents the center of the toilet flange.
Six Facts About Testing for Ethyl Glucuronide (EtG) Six Facts About Testing for Ethyl Glucuronide (EtG) 1  Ethyl glucuronide is a direct, minor metabolite that can be used as a biomarker for ethanol exposure.  Like any other toxin, ethanol is excreted from the body in a variety of ways.
ETG in urine is only detected when ethanol (alcohol) is ingested. While ethanol is eliminated rapidly, ethyl glucuronide (ETG) is detectable for up to 80 hours after the elimination of ethanol from the body.
