Chromatography with Bromocresol Green Electrophoresis for Albumin and Globulin Analysis (Serum/Plasma)

What This Test Measures

The test uses an electric field to separate different proteins in your serum or plasma based on their size and charge. Albumin, a smaller protein, moves faster and appears closer to the starting line, while globulins, which include various immune and transport proteins, move more slowly. Bromocresol green dye helps visualize these bands under specific lighting conditions.

Clinical Uses

This test is primarily used to evaluate conditions such as liver disease, kidney disease, or certain types of protein disorders. It can also help monitor treatment responses in patients with chronic conditions affecting protein metabolism.

Sample Collection and Preparation

A blood sample is collected from a vein, typically in the arm. The blood is processed to separate the serum or plasma, which is then analyzed in the lab. No special preparation is needed, but fasting may be advised depending on your specific test instructions.

What to Expect During the Test

The process is quick and usually done in a clinic or lab setting. You may feel a brief pinch when the needle is inserted, but the procedure itself takes only a few minutes. Results are typically available within a few days, depending on lab processing times.
