Serum or Plasma Electrophoresis (Qualitative)
This test measures the distribution of proteins in your blood using gel electrophoresis, a method that separates proteins based on size and charge. It helps identify abnormalities in protein patterns that may indicate conditions like multiple myeloma, certain types of anemia, or other blood disorders.

What This Test Measures
Electrophoresis splits blood proteins into five main bands: albumin, alpha-1, alpha-2, beta, and gamma globulins. Each band represents different protein types, including antibodies, enzymes, and transport proteins. Abnormal band patterns can signal underlying health issues.
Why It’s Done
Doctors use this test to diagnose or monitor conditions like multiple myeloma (a cancer of plasma cells), chronic liver disease, or autoimmune disorders. It may also help evaluate symptoms like fatigue, swelling, or unexplained weight loss.
Sample Collection and Preparation
A blood sample is drawn from a vein, typically in your arm. The blood is then processed to separate serum or plasma, which is placed on a gel for electrophoresis. The gel is placed in an electric field to separate proteins by size and charge.
Common Conditions Monitored
Abnormal results may point to conditions such as protein-losing syndromes, infections, or genetic disorders. For example, high gamma globulins could suggest multiple myeloma or other plasma cell disorders, while low albumin might indicate liver disease or malnutrition.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is crucial for identifying protein abnormalities that may not be detected by routine blood tests. It helps guide treatment decisions, especially in conditions where protein patterns are key diagnostic markers. Results are interpreted by a healthcare provider based on your overall health and symptoms.
