Electrophoresis of Serum Proteins (Bromocresol Green)
This test measures the distribution of different protein fractions in your blood serum using a technique called electrophoresis. It helps identify abnormalities in protein levels that may indicate conditions like liver disease, kidney problems, or certain immune disorders.
["This test helps doctors assess protein balance in your blood, often used to detect underlying health issues."]

What This Test Measures
Electrophoresis separates blood proteins into distinct bands based on their size and electrical charge. The test uses bromocresol green dye to identify specific protein groups, including albumin, globulins (such as alpha, beta, and gamma globulins), and other components. The results provide a visual profile of protein distribution.
Why It’s Done
Doctors may order this test to investigate symptoms like unexplained weight loss, fatigue, swelling, or signs of organ dysfunction. It can also help diagnose conditions like multiple myeloma, liver disease, or chronic inflammation.
Sample Preparation and Testing Process
A blood sample is drawn, and the serum (liquid part after clotting) is separated and prepared for electrophoresis. The sample is placed in an electric field, causing proteins to migrate at different rates, creating visible bands. Bromocresol green dye binds to certain proteins, enhancing their visibility.
Common Conditions Evaluated
This test is particularly useful for identifying imbalances in albumin and globulin levels. Low albumin may suggest liver or kidney disease, while abnormal globulin patterns can indicate immune system disorders or chronic infections.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal results may signal underlying health issues, such as liver disease (reduced albumin), immune disorders (elevated gamma globulins), or kidney problems (altered protein fractions). Early detection can guide treatment decisions, including monitoring for conditions like cirrhosis, multiple myeloma, or autoimmune diseases.
