Protein Electrophoresis, Serum (Qualitative)
This test measures the different types of proteins in your blood serum using electrophoresis, a technique that separates proteins based on size and charge.
["Helps identify abnormal protein patterns that may indicate conditions like multiple myeloma or other blood disorders."]

What Proteins Are Measured?
Electrophoresis separates proteins into five main bands: albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins. Each band represents a group of proteins with similar electrical charges and sizes. Abnormal patterns may suggest conditions affecting protein production or function.
Common Uses and Conditions
This test is often used to diagnose or monitor conditions such as multiple myeloma (a cancer of plasma cells), Waldenström macroglobulinemia, and other disorders involving abnormal protein production. It may also help evaluate liver or kidney disease, as these organs can affect protein levels.
Preparation for the Test
No special preparation is needed for this test. You may eat and drink normally before your blood draw. Your healthcare provider will explain how to prepare if you have any specific instructions.
What to Expect During the Test
A healthcare professional will draw blood from a vein in your arm. You may feel a slight pinch or discomfort, but it usually lasts only a few seconds. The process is quick, and you can return to your normal activities immediately afterward.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal protein patterns detected in electrophoresis can indicate underlying health issues. For example, elevated gamma globulins may suggest multiple myeloma or other plasma cell disorders. Low albumin levels might point to liver disease or malnutrition. Your healthcare provider will interpret the results in the context of your overall health and symptoms.
