Serum or Plasma Protein Electrophoresis (Qualitative) with Bromocresol Green Probe

Published: August 9, 2026Updated: August 16, 2026

This test measures the different types of proteins in your blood using electrophoresis, a method that separates proteins based on size and charge. A bromocresol green dye is used to detect specific protein fractions.

Quick summary

["This test helps identify abnormal protein patterns that may suggest conditions like multiple myeloma, liver disease, or other disorders affecting protein production."]

What This Test Measures

Electrophoresis separates blood proteins into distinct bands based on their electrical charge and molecular weight. The bromocresol green probe helps visualize certain protein fractions, such as albumin, alpha-globulins, beta-globulins, and gamma-globulins. Abnormal patterns may indicate conditions like monoclonal gammopathy or protein disorders.

Why It’s Done

Your healthcare provider may order this test to diagnose or monitor conditions affecting protein levels, such as chronic liver disease, kidney disease, or certain cancers. It can also help assess protein synthesis or degradation in systemic diseases.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in your arm. The serum or plasma is then processed and analyzed using electrophoresis to separate proteins. The bromocresol green probe is applied to detect specific protein fractions visually.

Common Conditions Monitored

This test is particularly useful for identifying abnormal protein bands that may signal conditions like multiple myeloma (a cancer of plasma cells), Waldenström macroglobulinemia, or other paraneoplastic syndromes. It can also help evaluate liver function or detect protein-losing syndromes.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal protein electrophoresis patterns can reveal underlying issues such as increased or decreased levels of specific proteins. For example, a prominent band in the gamma region may suggest monoclonal gammopathy, while altered alpha or beta bands could indicate liver or kidney disease. Early detection can guide treatment decisions.

Frequently asked questions

What does a normal result mean?
A normal result typically shows balanced protein bands with no unusual spikes or shifts. This suggests your blood proteins are within expected ranges, but further testing may still be needed if symptoms persist.
How often should I get this test?
Frequency depends on your health condition. If you have a known disorder like multiple myeloma, your doctor may schedule follow-up tests every few months. Otherwise, this test is usually reserved for specific clinical situations.
Can diet or medications affect this test?
Dietary changes or certain medications (e.g., steroids, chemotherapy) may influence protein levels. Always inform your healthcare provider about any medications or dietary supplements you’re taking before the test.
