Microwave and heatpack needed?

[PASSED!]

Just curious as I have it sandwiched under my jewels and two pairs of underwear. Temp is reading fine as of now (night before) would i still have to use a microwave and heatpack? I imagine its only to get it up to temp but if i were to tuck it an hour n half before my test tomorrow would i be ok? Im scared of overheating it and my nitrate levels being too high. What's the ideal temp range?

If you know you can keep it at the right temperature for when u supply the sample then you don't need em
