They rescheduled the test for tomorrow morning. I tested myself again this morning on my first void and still no solid line showing so I feel my best bet is to sub. I have a urine sample that had been frozen within 30 minutes of collection and was kept on ice for the 1.5 hour trip here. I assume once thawed it will be good.

I plan to tuck it in my underwear and I was wondering if I should put a heat pack on it to keep it warm? I feel like I could cool it down but I won't be able to easily warm it more.

My heat pack says heats to 100*, Before when I subbed I stuck the urine bottle in my shoe wrapped in a heat pack and I didn't have any problems, it was slightly too warm but I just dipped the closed bottle into the toilet until it cooled some.

Does my plan sound okay? I know it worked before but my first test was done by a radiologist so I'm not even sure she read the temperature correctly.
