Thanks for all your help and support.

Subbing is the way to go, here is what I did.

Nuked quick fix and check with digital thermometer before I left the house and it was at 105F. I had on two pairs of small boxer briefs...very tight. I tucked the QF around my taint area and I put the heating pad between the two pairs of boxers to shield the heat.

10 min. drive to clinic. On the walk from the car the bottle of QF climbed up my crack. I went into the bathroom and checked the temp..96F, ditched the heating pad and walked into the office.

Filled out the paperwork, was given the cup and asked to empty my pockets. Washed my hands, went into the bathroom. Took out the QF, shook it and poured it in the cup. Temp was perfect, the sample was a little low so I shot a few ml's of my own urine into the sample. I diluted before I left the house and tested myself with a home kit just to make sure I was in the negative zone. It was nice b/c my urine added some bubbles to the cup. Walked out, she checked the temp and all was good and now I just have to wait a few days.

Again thanks to all!
