Bromocresol Green Serum Protein Electrophoresis (Qualitative)

Published: August 9, 2026Updated: August 16, 2026

This test measures the distribution of proteins in your blood using an electrophoresis method with bromocresol green dye. It helps identify patterns of protein separation that may indicate conditions affecting protein synthesis, breakdown, or transport.

What This Test Measures

Electrophoresis separates blood proteins based on their size and electrical charge. Bromocresol green dye binds to proteins, allowing visual differentiation of fractions (e.g., albumin, globulins) under an electric field. This qualitative method helps detect shifts in protein composition, which can signal underlying health issues.

Common Uses and Indications

This test may be used when doctors suspect conditions like chronic liver disease, nephrotic syndrome, multiple myeloma, or other disorders that alter protein synthesis, storage, or breakdown in the body.

How the Test Works

A small blood sample is drawn and placed in a gel medium. An electric current is applied, causing proteins to migrate toward the opposite charge. After staining with bromocresol green, the gel is examined for distinct bands representing different protein groups.

Preparation and Sample Collection

No special preparation is needed, but fasting may be advised depending on your doctor’s instructions. A healthcare provider will collect your blood sample in a sterile tube.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why might my doctor order this test?
Your doctor may recommend this test if they suspect conditions like liver disease, kidney problems, or immune system disorders that alter protein levels in your blood.
What do the results mean?
Results show the distribution of protein bands. Normal results have distinct bands for albumin and globulins. Abnormal patterns may require further testing or evaluation by a specialist.
How long will it take to get results?
Results are typically available within 1–2 business days, depending on lab processing times.
