What This Test Measures

The bromocresol green dye binds to different protein fractions in your serum, separating them based on size and charge. This creates a pattern that reflects the proportion of albumin, globulins, and other proteins.

Why It’s Done

Your healthcare provider may order this test to check for abnormalities in protein levels, such as low albumin (which can indicate liver or kidney disease) or unusual globulin patterns (which may suggest immune system issues or metabolic disorders).

Common Conditions Monitored

This test is often used to monitor conditions like cirrhosis, nephrotic syndrome, or certain autoimmune diseases where protein balance is disrupted.

Sample Collection

A blood sample is drawn from a vein, usually in your arm. The serum portion is separated and analyzed for protein patterns.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: Protein Electrophoresis with Bromocresol Green helps identify imbalances in protein fractions that may indicate underlying health issues, guiding treatment decisions.

Short name

BCG Protein Electrophoresis

Frequently asked questions

How long does it take to get results from this test?
Results are typically available within 24 to 48 hours, depending on lab processing times.
What does a normal result look like?
A normal result shows a distinct banding pattern with clear separation of albumin and globulin fractions, though exact appearance varies by lab.
Can I eat or drink anything before this test?
No special diet or fasting is required for this test, but follow any general blood test preparation instructions your provider gives you.
