When higher-than-normal amounts of protein are in the urine, it’s called proteinuria. This is often a sign of kidney damage and disease.
| The test doesn’t show what kinds of protein are in the urine. To determine this, your doctor may also order tests such as a serum and urine protein electrophoresis. |
| For a random urine sample, normal values are 0 to 20 mg/dL. |
