What This Test Measures

Electrophoresis separates blood proteins into fractions, such as albumin, globulins, and other components, which can reveal imbalances or unusual patterns. This is typically done using a gel or paper medium and an electric current.

Why It’s Done

Doctors may order this test to diagnose or monitor conditions like multiple myeloma, lymphoma, liver disease, kidney disease, or certain autoimmune disorders. It can also help assess protein disorders or screen for hidden blood diseases.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The serum (liquid part after clotting) is then prepared for analysis by applying it to a gel or paper substrate and running it through an electric field to separate proteins.

Common Conditions Monitored

This test helps detect abnormal protein levels that may indicate conditions such as multiple myeloma (cancer of plasma cells), benign monoclonal gammopathy, liver or kidney disease, or other metabolic disorders.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal electrophoresis results can signal underlying health issues, such as the presence of monoclonal proteins (spikes) that may require further testing for conditions like plasma cell disorders. Low albumin levels may indicate liver or kidney problems, while high globulin levels could suggest immune system or inflammatory conditions. Always discuss results with your healthcare provider for accurate interpretation.

Frequently asked questions

How long does it take to get results from this test?
Results are typically available within 24 to 48 hours, depending on lab processing times and your healthcare provider’s workflow.
Can I eat or drink anything before this test?
No special diet is required for this test. However, inform your healthcare provider if you’re on any medications that might affect blood protein levels.
Is there any risk or discomfort with this blood draw?
The blood draw is generally quick and well-tolerated. You may feel slight discomfort or bruising at the site, but serious risks are rare. Always follow your healthcare provider’s instructions for post-procedure care.
