are proteins found in urine
Proteinuria is when protein is found in the urine. As blood moves through the kidneys, the kidneys filter out waste, excess fluid and salt. These wastes leave the body in urine. Usually, no protein is found in urine because most proteins are too big to go through the kidneys.If your doctor finds protein in your child's urine, it means your child's kidneys may not be working as they should--possibly because of inflammation (swelling).f there is only a little protein in the urine, your child probably has a benign (harmless) condition such as orthostatic proteinuria (see below). If a lot of protein is found in your child's urine, a more serious kidney disease might be the problem.
