I don't know where your getting your heat pads but you can go in any store and get therma care heat pads or any heat pad for that matter and put it in the first pair of tighty whities as insurance. 94.2 is acceptable but I like to turn in a sample at least 97 degrees. Use a heat pad as insurance.

You can have it on the sample at least 60 minutes before the test and you will know if it's working or not. It can't hurt to have it but it can hurt not to have it. Also I have done the rubbing your finger on your jeans and placing it gently on the strip but use a heat pad and you shouldn't need anything else. Good luck...:thumbsup:
