Have you been practicing the pouring of the sample from the bottle to the "sample cup" (using warmed water instead of urine)? If so, you would notice a temperature drop which is a natural occurrence whenever warmed liquids are transferred to a cooler container. The temp drop can be as much as 5 degrees depending on how cold the empty sample cup is.


During practice, shoot for about 99-100F at the sub bottle, and after pouring into the cup, make note of its temp drop for 4 minutes. I say 4 minutes because at the facility, the collector is supposed to recieve the urine sample and check its temp within 4 minutes after being voided by the donor.

Oftentimes when I encounter an empty sample cup that is cold (due to the A/C being turned way up at the facility), I "prewarm" the empty sample cup by tucking it in my armpit as Im closing the bathroom door, unzipping, etc.
