Protein Electrophoresis on Serum (Qualitative)
This test measures the different types of proteins in your blood, including albumin and globulins, to help identify abnormalities in protein distribution.
["Helps diagnose conditions like multiple myeloma, liver disease, or kidney problems by checking protein patterns."]

What Proteins Are Measured?
Your blood sample is separated into fractions based on protein size and charge. Common bands include albumin (fast-moving), alpha, beta, and gamma globulins (slower-moving). Abnormal bands or shifts may indicate disease.
Why Is This Test Done?
A doctor may order this test to investigate symptoms like unexplained weight loss, fatigue, swelling, or signs of organ dysfunction (e.g., liver or kidney issues). It’s also used in screening for conditions like multiple myeloma or autoimmune diseases.
Sample Preparation and Testing Process
A blood sample is drawn, and serum is separated. The sample is then run through an electric field in a gel medium, causing proteins to migrate at different speeds. Results are visually interpreted as bands or patterns.
Common Conditions This Test Helps Diagnose
Abnormal patterns may signal conditions like multiple myeloma (excess monoclonal proteins), liver disease (reduced albumin), or chronic inflammation (increased globulins). It’s not a definitive test alone but guides further evaluation.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: Protein electrophoresis is critical for identifying monoclonal gammopathies (e.g., plasma cell disorders), evaluating protein synthesis disorders, or monitoring treatment responses in conditions like lupus or rheumatoid arthritis. It’s often used alongside other tests for comprehensive diagnosis.
