How do you pass urine tests?

You don;t pass urine tests.

A doctor or nurse will take a sample of you urine, and test it for sugar , acids, etc.,

To make sure you urine is as clean as possible, over the previous few hours, just drink one or two pints of water. This will 'flush' your system out, and the tests will be more correct.

Avoid sugar, or other sweet foods, as sugar will show in urine tests.
