Serum or Plasma Substance Concentration by Immunoassay (Bromocresol Green or Bromocresol Purple Electrophoresis)

What This Test Measures

The test detects a particular substance (such as a protein or enzyme) in your blood using a specialized method. Bromocresol green or purple dye is often used in electrophoresis to separate and quantify proteins. This can include tests for substances like albumin, globulins, or other proteins critical for blood health and function.

Why It Matters in Your Health

Blood protein levels can indicate liver function, kidney health, nutritional status, or the presence of certain genetic disorders. For example, low albumin might signal liver disease or malnutrition, while abnormal protein patterns could suggest conditions like multiple myeloma or other protein-related disorders.

Common Uses in Medical Care

Doctors may order this test to diagnose or monitor liver conditions (e.g., cirrhosis), evaluate protein synthesis, screen for genetic disorders affecting protein production, or assess overall protein balance in the body.

Sample Collection and Preparation

A blood sample is drawn from a vein, typically in your arm. The blood is then processed to separate serum or plasma, which is sent to a lab for testing. This process usually takes a few minutes, and you may feel slight discomfort but no lasting effects.
