Protein Electrophoresis on Serum (Qualitative)
This test measures the different types of proteins in your blood, including albumin and globulins, to help identify conditions like kidney disease, liver problems, or certain cancers.
["This test helps doctors check for abnormal protein patterns that may signal underlying health issues."]

What Proteins Does This Test Measure?
Electrophoresis separates blood proteins based on their electrical charge and size. The test identifies key protein bands: albumin (fast-moving), alpha, beta, and gamma globulins (slower-moving). Abnormal patterns may indicate conditions like multiple myeloma, liver disease, or chronic inflammation.
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 kidney disease, autoimmune disorders, or certain cancers. It’s also used to monitor treatment progress in some cases.
How Is the Test Performed?
A blood sample is drawn from a vein, usually in your arm. The serum portion is separated and placed in a gel for electrophoresis. Results show protein distribution patterns on a report, which your doctor interprets.
What Do the Results Mean?
Normal results show balanced protein bands. Abnormal patterns (e.g., extra bands, missing bands, or shifts) may signal conditions like protein-losing syndromes, infections, or malignancies. Your doctor will discuss findings with you.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test plays a critical role in diagnosing and managing conditions affecting protein metabolism. For example, elevated gamma globulins may indicate multiple myeloma or other plasma cell disorders, while low albumin could signal liver or kidney disease. It’s often used as a screening tool or to monitor treatment efficacy in chronic diseases.
