Serum/Plasma Protein Electrophoresis with Bromocresol Green (BCG) Dye Binding
This test measures the distribution of different protein types in your blood using a dye that binds to specific proteins, helping identify abnormalities in protein levels.
["Assists in diagnosing conditions affecting blood protein balance, such as kidney disease or certain cancers."]

What This Test Measures
The test uses bromocresol green dye to separate and quantify proteins in your blood, including albumin, globulins, and other fractions. This helps assess overall protein composition and identify shifts that may indicate health issues.
Common Uses
This test is often used to diagnose conditions like multiple myeloma, liver disease, kidney problems, or certain autoimmune disorders. It can also help monitor treatment progress for these conditions.
How the Test Works
A small blood sample is drawn and mixed with bromocresol green dye. The proteins in the sample bind to the dye differently, allowing them to separate during electrophoresis. The resulting pattern helps determine protein concentrations.
Preparation Tips
No special preparation is needed, but avoid heavy meals or excessive alcohol before the test. Hydration is generally encouraged unless advised otherwise by your healthcare provider.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal protein patterns may signal underlying health problems, such as an overproduction of certain proteins (e.g., monoclonal gammopathy in multiple myeloma) or reduced protein levels (e.g., in liver or kidney disease). Early detection can guide treatment decisions.
Short name
