Serum Protein Electrophoresis (Qualitative)

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

This test measures the different types of proteins in your blood using a technique called electrophoresis. It helps identify abnormal protein patterns that may indicate conditions like multiple myeloma, liver disease, or other disorders.

What Is Electrophoresis Used For?

Electrophoresis separates blood proteins into fractions (albumin, globulins, etc.) based on size and charge. This helps detect conditions like chronic inflammation, infections, or cancers that alter protein composition. For example, it may show elevated or unusual globulin bands in diseases like multiple myeloma or autoimmune disorders.

How Is the Test Performed?

A blood sample is drawn and placed in a gel or agarose medium. An electric current is applied, causing proteins to migrate toward the opposite electrode. After staining, bands representing different protein types appear, allowing for visual analysis.

Preparation and Sample Requirements

No special preparation is needed, but fasting may not be required. Your blood sample is taken from a vein, and the test is typically done in a lab. Results are qualitative (descriptive) rather than numeric, so they’re interpreted by a healthcare provider.

When Might You Need This Test?

Your doctor may order this test if you have symptoms like unexplained weight loss, fatigue, frequent infections, or signs of liver/kidney disease. It’s also used in screening for conditions like monoclonal gammopathy (abnormal protein production).

Reference range

NCBI: pH 7.35-7.45N/A

Specimen: urine

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.

Abnormal electrophoresis results can reveal hidden health problems, such as: - **Monoclonal gammopathy** (e.g., multiple myeloma or benign conditions like benign monoclonal gammopathy of undetermined significance). - **Liver disease** (e.g., cirrhosis, where albumin levels drop). - **Inflammatory or autoimmune disorders** (e.g., rheumatoid arthritis, where globulins rise). - **Infections** (e.g., chronic bacterial/viral conditions affecting protein balance). Doctors use these findings to guide treatment or monitor conditions like cancer or organ dysfunction.

Frequently asked questions

How long does it take to get results?
Results are usually available within 1–3 business days, depending on lab processing times. Since this is a qualitative test, your doctor will discuss the findings with you.
Can I fast before this test?
No fasting is required for this test. However, if you have specific medical conditions (e.g., diabetes), always follow your doctor’s instructions.
What if my results show abnormal protein bands?
If your electrophoresis shows unusual bands, your doctor may recommend further testing (e.g., urine protein tests, bone marrow exams, or follow-up bloodwork) to determine the cause. Conditions like multiple myeloma or liver disease often require additional evaluation.
