Serum/Plasma Total Protein with Electrophoresis Separation (Qualitative)
This test measures the overall protein content in your blood and separates proteins into different categories (e.g., albumin, globulins) using electrophoresis. It helps identify abnormal protein distributions that may signal conditions like liver disease, kidney problems, or certain cancers.

What Is Protein Electrophoresis Used For?
Protein electrophoresis helps doctors diagnose and monitor conditions by showing how proteins are distributed in your blood. For example, it can detect abnormal protein spikes that might indicate diseases like multiple myeloma, liver disease, or kidney disorders. It also supports evaluating immune system function by analyzing globulin levels.
How Is This Test Performed?
A small blood sample is drawn, and the serum or plasma is placed in a gel. An electric current runs through the gel, causing proteins to move based on their size and charge. Afterward, a dye stains the proteins, revealing bands that represent different protein types.
Preparation for the Test
No special preparation is needed, but you may be asked to fast for 8–12 hours before the test if instructed by your healthcare provider. Avoid heavy meals or certain medications that could affect protein levels.
Common Conditions Monitored
This test is often used to screen for conditions like multiple myeloma (cancer of plasma cells), liver disease (e.g., cirrhosis), kidney disease, and certain autoimmune disorders. It may also help assess protein malnutrition or track treatment responses.
Clinical interpretation
