Urine Tests (original) (raw)

The kidneys make urine (YER-in) as they filter wastes from the bloodstream. When working as they should, the kidneys keep things that the body needs in the blood, like protein, and get rid of anything the body doesn’t need, like extra water and salts. But sometimes, other things can be in urine, like protein, glucose, or blood cells. These can be signs of a health problem.
