Protein monoclonal isotype

A protein in urine test measures how much protein is in your urine (pee). Normally, you have very little protein in your urine. A large amount of protein in urine (proteinuria) may mean you have a kidney problem. Your kidneys are organs that filter extra water and waste out of your blood to make urine.

A protein in urine test is often part of a urinalysis, which may include a visual check of your urine (pee) sample, tests for certain chemicals, and an examination under a microscope to look for certain types of cells. A urinalysis is used to check your general health, including the health of your urinary tract (which includes your kidneys, ureters, bladder, and urethra).
