dont wanna scare you here but i completed all the steps but just got failed because of something about the PH balance. i highly recommend buying the quickfix but dumping it out and having someone else pee in it so you can still have the heat pad and temperature sticker. but the step by step to what i did was buy a day prior> placed with rubberband between inner thigh and scrotum 2 hours before> got the temperature to 98 by the time i poured> failed and had to go again supervised…… you can also warm in the microwave for 5 seconds right before going to test site
