Serum or Plasma Protein Electrophoresis (Bromocresol Green)
This test measures the distribution of proteins in your blood, separated by size and charge, using a dye called bromocresol green. It helps identify abnormalities in protein patterns that may suggest conditions like multiple myeloma, liver disease, or other disorders.

What Proteins Does This Test Measure?
The test separates blood proteins into fractions, including albumin, alpha-globulins, beta-globulins, and gamma-globulins. Each fraction may contain different proteins like immunoglobulins, enzymes, or other substances that can be affected by disease.
Why Might Your Doctor Order This Test?
Your doctor may recommend this test if they suspect conditions like multiple myeloma (a cancer of plasma cells), chronic liver disease, kidney disease, or other disorders that alter protein production or distribution in the blood.
How Is the Test Performed?
A small blood sample is drawn from a vein, typically in your arm. The serum or plasma is then separated and mixed with bromocresol green dye. An electric current is applied to separate proteins based on their size and charge, creating bands that reflect protein concentration.
What Does the Test Result Mean?
Results show the relative amounts of each protein fraction. Abnormal patterns, such as increased or decreased bands, may indicate specific health concerns. Your doctor will interpret the results in the context of your medical history and symptoms.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: This test is crucial for diagnosing and managing conditions that affect protein synthesis, storage, or breakdown. For example, an abnormal electrophoresis pattern may reveal monoclonal gammopathy (a hallmark of multiple myeloma) or signs of liver or kidney dysfunction. Early detection can guide treatment decisions.
