Will my doctor do other kidney tests?

Maybe. Your doctor might test your blood to measure the amounts of creatinine (kree-AT-ih-nin) and urea (yoo-REE-uh). These are waste products your body makes. If your kidneys are not cleaning them out of your blood, they can build up and make you sick.

Your doctor might also ask you to collect your urine in a large container for a whole day or just overnight.
