Urine Test

Doctors order urine tests for kids to make sure that the kidneys and certain other organs are working as they should, or when they think that a child might have an infection in the kidneys, bladder, or other parts of the urinary tract.

The kidneys make urine (pee) as they filter wastes from the bloodstream, while leaving substances in the blood that the body needs, like protein and glucose. So when urine contains glucose, too much protein, or has other irregularities, it can be a sign of a health problem.
