I need to know how long a urine sample will last for a drug test. It has been in a secured bottle with lid on for a week. I see the doctor tomorrow morning and need to know if the sample will still work

In brief: No, it won't

Firstly, many doctors want an observed sample where they know for a fact that it is your urine.
Even refrigerated, tests will not be valid after a week because chemicals decompose, particularly in the acid environment of urine.

In brief: Unless

Unless it's been refrigerated, it's basically no good after a couple of hours.
Sorry.
