Gotcha suzieque. i had read a reference to rubbing on jeans and fingers but I wasn't sure what they meant. One thing I have going for me is that the nurse doesn't seem to enjoy handling specimens and I don't recall her paying much attention to the temp. strip. sux that I will have to have a bottle in my crotch for 12 hr shifts, but I only work 5 day shifts a month when they would test me. Thanx again.
