Definition. Protein in urine â known as proteinuria (pro-tee-NU-ree-uh) â is any excess amount of protein found in a urine sample. Protein is one of the substances identified during urinalysis, a test to analyze the content of your urine. Low levels of protein in urine are normal. Temporarily high levels of protein in urine aren't unusual either, particularly in younger people after exercise or during an illness. If a urinalysis shows you have protein in your urine, you might have a follow-up test that determines how much protein is present and whether it's a cause for concern.
