What This Test Measures

The bromocresol green dye binds to specific protein fractions during electrophoresis, separating them by size. This process helps evaluate the concentration and distribution of proteins like albumin and globulins, which can indicate underlying health concerns.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like swelling, unexplained weight loss, or signs of organ dysfunction. It’s also used to monitor chronic conditions like chronic kidney disease or liver disease.

Common Conditions Monitored

Abnormal results may suggest conditions such as nephrotic syndrome (kidney disease), liver disorders, or certain autoimmune diseases where protein levels are disrupted.

Sample Collection

A small blood sample is drawn from a vein, typically in your arm. The serum (liquid part of blood after clotting) is then analyzed in the lab.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a normal result mean?
A normal result typically shows balanced protein distribution, meaning your blood has appropriate levels of albumin and globulins for your body’s needs. However, individual results depend on your health status and may vary slightly.
How long does it take to get results?
Results are usually available within 1 to 3 business days, depending on lab processing times. Follow up with your healthcare provider to discuss the findings.
Can diet affect this test?
Dietary changes, such as high-protein or low-protein diets, may influence protein levels. Avoid extreme dietary shifts before testing, and follow your provider’s instructions for fasting or other preparations.
