Understanding What it Means to Have Protein In Your Urine

Description

The kidneys are best known for making urine. This rather simple description does not tell the whole story. This brochure describes other important functions of the kidneys; including keeping protein in the blood and not letting any of the protein in the liquid (plasma) part of blood escape into the urine.

“Proteinuria” is when kidneys allow proteins to appear in the urine and be lost from the body. Proteinuria is almost never normal, but it can be normal – rarely – in some healthy, active children or young adults.
