Serum Protein Electrophoresis (Qualitative)

Published: August 9, 2026Updated: August 16, 2026

This test measures the different types of proteins found in your blood serum, separated by size and charge. It helps identify abnormalities in protein distribution that may indicate conditions like multiple myeloma, liver disease, or other disorders.

What Does the Test Measure?

Serum protein electrophoresis separates proteins into fractions (e.g., albumin, alpha-globulins, beta-globulins, gamma-globulins) using an electric field. Each fraction represents a distinct group of proteins, which can be visualized as bands on a gel. Abnormal patterns may suggest underlying conditions.

Why Might You Need This Test?

Your doctor may order this test to diagnose or monitor conditions like multiple myeloma (cancer of plasma cells), liver disease, kidney disease, or autoimmune disorders. It can also help assess protein malnutrition or detect unusual protein spikes.

Sample Preparation and Testing Process

A blood sample is drawn, and serum is separated for analysis. The serum is then applied to a gel and subjected to an electric current, causing proteins to migrate based on their charge and size. After staining, bands are analyzed for relative protein concentrations.

Common Conditions Monitored

Abnormal results may reveal conditions such as monoclonal gammopathy (e.g., multiple myeloma), hypoalbuminemia (low albumin), or increased globulins (e.g., in chronic inflammation or autoimmune diseases).

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a high or low protein band mean in my results?
High or low levels in specific protein bands may indicate different health concerns. For example, an unusual spike in one band could suggest a monoclonal protein (seen in myeloma), while low albumin might point to liver or kidney issues. Always discuss your results with your healthcare provider.
How long does it take to get my test results back?
Results are typically available within 24 to 48 hours, depending on your lab. Your doctor will explain what the findings mean in the context of your overall health.
Can I eat or drink anything before this test?
No special preparation is needed for this test. However, inform your doctor about any medications you’re taking, as some may affect results.
