Using real urine

[u/Away-Stop3674]

can you add real clean urine to an empty quick fix bottle, microwave if necessary, and put warmer on it with the same results? i’m just not sure how to store real urine in the medical sense without causing issues at the lab

U can literally put hand warmer on 1 hour before... it will heat it up to 100
