storage for my clean pee..

Hey there :) Fiance is getting his preemployment screening done sometime this next week. Im getting the pee tonight, I cant get it the day of because my donator leaves in the morning. Air tight container in the freezer with extra time to warm up? Also.. for finances sake.. Does it matter what sex your donator is? Ours is female and obviously, hes not :-p I work in a hospital and unless we order the test, it doesn't get done. i.e, we dont test for testosterone or estrogen with our drug tests. Anybody with personal experience here? Thank you :rasta: now to go smoke. Stay safe everybody!
