Serum Protein Electrophoresis (Qualitative)

Published: August 9, 2026Updated: August 17, 2026

This test measures the distribution of different protein fractions in your blood serum, helping identify abnormalities in protein composition that may signal conditions like multiple myeloma, liver disease, or chronic inflammation.

What This Test Measures

Serum protein electrophoresis separates proteins into five main bands: albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins (including immunoglobulins). Each band reflects the concentration and type of proteins present, which can indicate underlying health issues.

Why It’s Done

Your doctor may order this test to investigate symptoms like unexplained weight loss, fatigue, swelling, or abnormal lab results. It’s also used to monitor conditions like multiple myeloma, autoimmune diseases, or liver/kidney disorders.

Sample Preparation

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

Common Conditions Monitored

Abnormal patterns (e.g., spikes in gamma globulins) may suggest conditions like monoclonal gammopathy (e.g., multiple myeloma), liver disease (e.g., cirrhosis), or chronic infections.

Reference range

Specimen: serum

No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is critical for diagnosing and managing conditions affecting protein synthesis or breakdown. For example, elevated gamma globulins may point to immune system disorders, while abnormal albumin levels could indicate liver or kidney disease. Early detection helps guide treatment decisions.

Frequently asked questions

What does a ‘qualitative’ result mean?
A qualitative result provides a visual or descriptive pattern (e.g., bands) rather than exact measurements. It helps identify if protein distribution is abnormal but doesn’t give precise numbers for each protein.
How long does it take to get results?
Results are typically available within 24–48 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, avoid alcohol for 24 hours before testing, as it may affect protein levels.
