Protein Electrophoresis (Serum/Plasma) with Bromocresol Green (BCG) Dye Binding Assay
This test measures protein levels in your blood using an electrophoresis method with a dye that binds to specific protein fractions, helping identify abnormalities in protein distribution.

What Is Protein Electrophoresis Used For?
Protein electrophoresis is primarily used to detect abnormalities in the distribution of proteins in your blood, such as those seen in conditions like multiple myeloma, liver disease, or certain types of kidney disease. It can also help monitor treatment progress or identify protein abnormalities in hereditary disorders.
How Is This Test Performed?
A small blood sample is drawn from your arm and processed to separate proteins based on size and charge. The BCG dye binds to certain protein fractions, allowing for visual or quantitative analysis of these components.
What Does the Test Measure?
The test measures the concentration of different protein fractions, including albumin, globulins, and other proteins, using the dye’s binding properties to differentiate between them. This helps identify shifts in protein composition that may indicate underlying health issues.
Preparation and Sample Collection
No special preparation is needed for this test. You may have a blood draw at a clinic or lab, and results are typically ready within a few days.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: Protein electrophoresis is critical for diagnosing conditions that alter protein levels, such as monoclonal gammopathy (e.g., multiple myeloma), liver dysfunction, or nephrotic syndrome. It can also aid in evaluating hereditary protein disorders or monitoring treatment responses in chronic conditions.
