Hi everyone,

I'd like to know how long can clean urine be stored for it to be valid to sub for a pee test? And what would be the best method, freezing? refrigeration?

And if I use a plastic bottle with a temperature strip, and heat the urine to acceptable test temperature, will that cause a test failure?

Any ideas would be appreciated. Thanks!
