What Proteins Does This Test Measure?

Electrophoresis separates blood proteins based on size and charge, creating distinct bands. Bromocresol green binds to proteins like albumin, globulins (including immunoglobulins), and other fractions. Abnormal band patterns may indicate conditions affecting protein production or breakdown.

How Is the Sample Collected?

A blood sample is drawn from a vein, typically in the arm. The serum (liquid part after clotting) is then analyzed in a lab using the bromocresol green dye method.

Why Might This Test Be Ordered?

Your healthcare provider may recommend this test if you have symptoms like unexplained weight loss, fatigue, swollen lymph nodes, or signs of organ dysfunction. It’s also used to monitor conditions like multiple myeloma, liver disease, or kidney problems.

What Could Abnormal Results Mean?

Abnormal results may show too much or too little of specific proteins. For example, high levels of certain globulins could suggest multiple myeloma or autoimmune diseases, while low albumin might indicate liver or kidney issues.

Clinical interpretation

Frequently asked questions

What does a normal result mean for my health?
A normal result suggests your blood proteins are within expected ranges, but it doesn’t rule out all conditions. Always discuss results with your provider, as they’ll consider your full medical history and symptoms.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on lab processing times. Your provider will contact you once they’re ready.
