What Does This Test Measure?

Electrophoresis separates blood proteins into five main bands: albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins (including immunoglobulins). Each band reflects the concentration and type of proteins present, which can indicate underlying health issues.

Why Might You Need This Test?

Your doctor may order this test if you have symptoms like unexplained weight loss, fatigue, swelling, or if they suspect conditions like multiple myeloma, lymphoma, liver disease, or kidney problems. It’s also used to monitor treatment progress in certain diseases.

How Is This Test Performed?

A small blood sample is drawn from a vein, typically in your arm. The serum portion is separated and placed in an electrophoresis chamber, where an electric current causes proteins to migrate to different positions based on their properties. The results are read visually or digitally to assess protein distribution.

What Are Common Findings?

Abnormal patterns may show increased or decreased levels of specific protein bands. For example, a spike in gamma globulins might suggest multiple myeloma or other monoclonal gammopathies, while altered albumin levels could indicate liver or kidney disease.

Frequently asked questions

What could abnormal results mean?
Abnormal results may indicate conditions such as multiple myeloma (a cancer of plasma cells), chronic liver disease, kidney disease, or certain autoimmune disorders. It’s important to discuss these findings with your healthcare provider for further evaluation.
How soon will I get my results?
Results are typically available within 24 to 48 hours, depending on your lab’s processing time. Your doctor will contact you to review the findings and next steps.
Is there anything I should do before the test?
No special preparation is usually needed, but avoid eating or drinking anything (except water) for 8–12 hours before the test if instructed by your doctor to prevent potential interference.
