What Proteins Does This Test Measure?

Electrophoresis splits serum proteins into bands corresponding to albumin, alpha-1 globulins, alpha-2 globulins, beta globulins, and gamma globulins (immunoglobulins). Abnormal band patterns may indicate conditions affecting protein production or breakdown.

How Is This Test Performed?

A blood sample is drawn, serum is separated, and proteins are applied to a gel. An electric current causes proteins to migrate toward the opposite electrode, creating distinct bands that are visualized and analyzed.

When Might You Need This Test?

Your healthcare provider may order this test if you have symptoms like unexplained weight loss, fatigue, swollen lymph nodes, or signs of organ dysfunction, or if they suspect conditions like multiple myeloma, amyloidosis, or chronic liver disease.

What Are Common Conditions Linked to Abnormal Results?

Abnormal results may show increased or decreased levels of specific protein fractions. For example, elevated gamma globulins could suggest immune disorders, while abnormal albumin levels may point to liver or kidney issues.

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.

This test is primarily used to diagnose or monitor conditions affecting protein synthesis, distribution, or degradation. It helps identify systemic diseases like multiple myeloma, where monoclonal proteins (M proteins) may appear, or conditions causing chronic inflammation or liver disease.

Frequently asked questions

Why was this test ordered for me?
Your doctor may have suspected a condition affecting protein levels in your blood, such as a blood cancer, liver problem, or immune disorder. This test helps visualize how proteins are distributed, which can guide further diagnosis.
What does it mean if my test results show unusual bands or patterns?
Unusual patterns may indicate an underlying condition, such as an abnormal protein production (e.g., monoclonal gammopathy) or changes in protein breakdown. Your doctor will discuss these findings with you and may recommend additional tests or treatments.
Can I prepare for this test in any special way?
No special preparation is needed. You may have a mild pinprick or slight discomfort from the blood draw, but this is normal. Avoid alcohol or certain medications (if instructed) to prevent potential interference with results.
