Serum Protein Electrophoresis (by Bromocresol Green)
This test measures the distribution of different protein types in your blood serum, often used to identify abnormalities in protein levels that may suggest conditions like multiple myeloma, liver disease, or other disorders.

What Does This Test Measure?
Serum protein electrophoresis separates blood proteins into distinct fractions (e.g., albumin, globulins, and other proteins) using an electrical charge. Bromocresol Green is a dye used to visualize these fractions during electrophoresis. This helps identify any unusual patterns that might indicate health concerns.
Why Might Your Doctor Order This Test?
Your doctor may recommend this test if they suspect conditions affecting protein levels, such as chronic infections, autoimmune diseases, kidney disease, or certain cancers. It’s also used to monitor treatment progress in patients with known protein-related disorders.
How Is the Test Performed?
A blood sample is drawn from a vein, typically in your arm. The serum portion is separated and analyzed using electrophoresis to separate proteins by size and charge. Results are interpreted by comparing the protein distribution to expected patterns.
What Are Common Findings?
Abnormal results may show shifts in protein bands, such as elevated or low levels of specific proteins. For example, a high globulin level might suggest inflammation or autoimmune disease, while unusual spikes could indicate conditions like multiple myeloma.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test plays a critical role in diagnosing and managing conditions that alter protein synthesis, distribution, or breakdown in the body. It provides valuable insights for tailoring treatment plans, especially in cases involving chronic diseases or cancer.
