What This Test Measures

Electrophoresis separates blood proteins into distinct bands, each representing different protein groups (e.g., albumin, globulins, including immunoglobulins). The qualitative result indicates the presence, absence, or relative amounts of these proteins without precise numerical values.

Why It’s Done

Your doctor may order this test to diagnose or monitor conditions affecting protein levels, such as infections, liver disease, kidney problems, or certain cancers like multiple myeloma.

Sample Preparation

A blood sample is drawn from a vein, typically in the arm. The serum (liquid part after clotting) is then analyzed in a lab using electrophoresis to separate proteins.

Common Conditions Monitored

Abnormal patterns may suggest conditions like monoclonal gammopathy (excess monoclonal antibodies), hypoalbuminemia, or inflammatory diseases. Results are interpreted by a healthcare provider based on your clinical context.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

How long does it take to get results from this test?
Results are usually available within 24 to 48 hours, depending on lab processing times. Follow-up with your doctor to discuss findings.
Can I eat or drink before this test?
No special preparation is needed. However, inform your doctor about any medications or conditions that might affect results.
What does it mean if my test shows unusual bands?
Unusual bands may indicate abnormal protein production, such as in multiple myeloma or other blood disorders. Your doctor will explain the results in detail and recommend next steps.
