Serum or Plasma Substance Concentration (Bromocresol Green) Electrophoresis
This test measures protein distribution in your blood using a dye called bromocresol green. It helps assess how proteins like albumin and globulins are separated in your serum or plasma.

What Is Bromocresol Green Electrophoresis Used For?
Electrophoresis with bromocresol green is primarily used to evaluate protein patterns in the blood. It can help identify abnormalities in protein fractions, such as those seen in conditions like multiple myeloma, liver disease, or certain autoimmune disorders.
How Is the Test Performed?
A small blood sample is drawn, usually from your arm. The serum or plasma is then separated and mixed with bromocresol green dye. An electric current is applied to the sample, causing proteins to move based on their size and charge. The distribution of proteins is then analyzed to determine their relative concentrations.
What Conditions Might Require This Test?
This test may be ordered if you have symptoms or conditions that could affect protein levels, such as unexplained weight loss, fatigue, swollen lymph nodes, or signs of liver or kidney disease. It can also be part of routine monitoring for certain chronic conditions.
Preparation for the Test
No special preparation is typically required. You may be asked to fast for a few hours before the test if instructed by your healthcare provider, but this is not always the case for electrophoresis.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Bromocresol green electrophoresis can reveal imbalances in protein fractions, which may indicate underlying health issues. For example, an abnormal protein pattern could suggest conditions like monoclonal gammopathy (seen in multiple myeloma), liver disease, or inflammatory disorders. Early detection can guide treatment decisions and monitor disease progression.
