What This Test Measures

Electrophoresis separates blood proteins into distinct bands (fractions) based on their electrical charge and molecular weight. Key fractions include albumin, alpha-globulins, beta-globulins, and gamma-globulins. Abnormal bands or shifts may indicate underlying health issues.

Common Uses and Conditions

This test is often used to diagnose or monitor conditions such as multiple myeloma (cancer of plasma cells), chronic liver disease, kidney disease, or inflammatory disorders. It may also help assess protein abnormalities in hereditary conditions.

Sample Preparation

A blood sample is drawn from a vein, typically in the arm. The serum portion (liquid after clotting) is then analyzed in a lab using electrophoresis. No special preparation is needed, but fasting may not be required unless specified by your healthcare provider.

What to Expect

After your blood is drawn, you may feel slight discomfort for a few seconds. The test itself is quick and painless. Results are usually available within a few days, depending on lab processing times.

Reference range

Adult: 3.5-5.0 mmol/LN/A

Specimen: whole-blood

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 may reveal elevated or low levels of specific proteins. For example, a high gamma-globulin fraction could suggest chronic inflammation or immune disorders, while unusual bands may point to monoclonal gammopathy (e.g., multiple myeloma). Your doctor will interpret results in the context of your symptoms and medical history.

Frequently asked questions

Why might my doctor order this test?
Your doctor may recommend this test if you have symptoms like unexplained weight loss, fatigue, frequent infections, or signs of organ dysfunction (e.g., liver or kidney issues). It’s also used as part of routine monitoring for certain chronic conditions.
How long will it take to get results?
Results are typically ready within 2–5 business days, depending on your lab’s workflow. Your healthcare provider will discuss findings with you during your follow-up visit.
Can I eat or drink before this test?
No special diet is required, but always follow your doctor’s instructions. If they specify fasting, avoid food or liquids (except water) for a set period before the test.
