Bromocresol Green Protein Electrophoresis (Serum)
This test measures protein distribution in your blood using a technique called electrophoresis with the Bromocresol Green dye. It helps assess the quality and quantity of different protein fractions, including albumin and globulins.
["This test helps evaluate protein balance in your blood, often used to diagnose or monitor conditions affecting protein synthesis or breakdown."]

What This Test Measures
Electrophoresis separates proteins in your serum based on size and charge. The Bromocresol Green dye binds to albumin and globulins, allowing for visual differentiation of protein bands. This process helps identify patterns of protein distribution that may indicate underlying health issues.
Common Uses
Protein electrophoresis with Bromocresol Green is primarily used to screen for conditions like hypoalbuminemia (low albumin levels), immune system disorders, or liver disease. It may also be part of a broader evaluation for chronic kidney disease or nutritional deficiencies.
How the Test Works
A small blood sample is drawn and mixed with the Bromocresol Green dye. The sample is then placed in an electric field, causing proteins to migrate toward the opposite charge. The dye highlights different protein fractions, creating distinct bands that are analyzed for concentration and distribution.
Preparation
No special preparation is needed for this test. However, inform your healthcare provider about any medications you’re taking, as certain drugs may affect protein levels.
