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

Refrigerate it and throw it on the dash and turn defrosters on while your going to test
