Electrophoresis of Serum Proteins (Qualitative)
This test measures the different types of proteins in your blood using a technique called electrophoresis. It helps identify abnormalities in protein distribution that may indicate conditions like kidney disease, liver problems, or certain cancers.

What This Test Measures
Electrophoresis separates blood proteins into distinct bands based on their size and electrical charge. The test typically looks at five main protein zones: albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins (antibodies). Abnormal patterns may appear if protein production or breakdown is disrupted.
Common Conditions Detected
This test can reveal conditions such as multiple myeloma (a cancer of plasma cells), chronic liver disease, kidney disease, or certain autoimmune disorders. High or low levels of specific proteins may also suggest nutritional deficiencies or metabolic disorders.
Sample Collection and Preparation
A blood sample is drawn from your arm, and the serum (liquid part after clotting) is sent to the lab. No special preparation is needed, but fasting may be advised depending on your doctor’s instructions.
How Results Are Interpreted
Results are compared to standard patterns. An abnormal pattern may require further testing, such as additional protein analysis or imaging, to determine the underlying cause.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Serum protein electrophoresis is a key diagnostic tool for identifying protein abnormalities that can guide treatment decisions. For example, elevated gamma globulins may suggest immune disorders, while abnormal albumin levels could indicate liver or kidney disease. Early detection helps manage conditions more effectively.
