Protein Electrophoresis, 24-Hour Urine

This test separates and measures the different types of proteins found in a urine sample collected over a full 24-hour period. It helps show how well the kidneys are filtering waste and whether abnormal proteins are leaking into the urine. This information assists doctors in investigating kidney damage or specific blood disorders like multiple myeloma. However, this test alone cannot diagnose a specific disease and often requires follow-up testing to identify the exact type of protein present.
