I may have a (pre-employment) test coming up. The main problem is that the job is for a doctorâ??s office with their own testing facility, so I probably wonâ??t be going to the hospital to take the test. My concern is that Iâ??ll go over for an interview or something and Iâ??ll be tested on the spot, so I want to be prepared (hence all my questions!).

For substitution, I ordered some Quick Fix, but it may not be here in time. A friend of mine can give me a clean sample, but theyâ??re a high school student with tons of activities, so theyâ??re not available all the time to give me a fresh sample. I plan on getting one from them and keeping it in the freezer. So my main questions are:

If I bring a sample of theirs and do not get tested that day, can human urine be heated multiple times like Quick Fix?
Once I thaw it out, does it stay good for the full 8 hours (even if itâ??s been frozen for a number of days)?
Also, does it necessarily need to be in an air tight container? I plan on keeping it in a bottle.

Thanks in advance.
