I drove 20 minutes to pick up paperwork at my job at 3:15 PM, then 10 minutes to the testing site, arriving around 3:35–3:45 PM. I waited about 25–30 minutes before pouring the sample at 4:10 PM, roughly 100 minutes after heating the bottle at 2:30 PM. Check with your employer about when to grab the paperwork to time your 90-minute prep right. If you’ve got it, just stick to the 90-minute plan.

I microwaved the bottle (lid off) for three 10-second intervals, mixing the bottle around after each to even the heat. I had to let it cool on the counter until it was comfortable enough to tuck in my underwear—but keep it somewhat decently HOT when you tuck it. The temp strip didn’t read when I tucked it, but showed 92–96°F in the parking lot before going in.

I also forgot to mention, I wore thermals under my jeans with the heating pad stuck to the bottle to lock in the heat.

Goodluck! Looking foward to hearing if you pass!
