What This Test Measures

The test uses bromocresol green dye to separate and quantify proteins in your blood into categories, including albumin, alpha-globulins, beta-globulins, and gamma-globulins. This helps detect imbalances that may signal conditions like multiple myeloma, liver disease, or immune disorders.

How the Test Works

A small blood sample is drawn and mixed with the dye. As the proteins separate during electrophoresis, the dye binds to specific protein groups, allowing for visual and quantitative analysis of their concentrations.

Common Uses

This test is often used to screen for conditions like monoclonal gammopathy (e.g., multiple myeloma), chronic liver disease, or other protein-related disorders. It may also help monitor treatment progress in patients with known protein abnormalities.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms like unexplained weight loss, fatigue, swollen glands, or signs of liver/kidney problems. It’s also used in follow-up care for patients with known protein disorders.

Frequently asked questions

Why was this test ordered?
Your doctor may have ordered this test to investigate symptoms, diagnose a suspected condition, or monitor an existing health issue related to abnormal protein levels in your blood.
What do abnormal results mean?
Abnormal results could indicate conditions such as protein disorders (e.g., monoclonal gammopathy), liver disease, or kidney problems. Your doctor will discuss these findings with you and may recommend further testing or treatment.
How long will it take to get results?
Results are typically available within a few days to a week, depending on your lab’s processing schedule. Follow up with your healthcare provider to discuss the results and next steps.
