Bromocresol Green Protein Electrophoresis (Serum)

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

This test measures protein distribution in your blood using a technique called electrophoresis with the bromocresol green dye. It helps assess the quality and quantity of proteins, including albumin and globulins, which can indicate underlying health conditions.

What This Test Measures

Electrophoresis separates proteins in your serum based on size and charge. The bromocresol green dye binds to specific protein fractions, allowing for visual or quantitative analysis of albumin and globulin levels. This helps identify shifts in protein composition that may signal systemic issues.

How the Test Works

A small blood sample is drawn and mixed with the bromocresol green dye. When placed in an electric field, proteins migrate toward the opposite charge, creating distinct bands. These bands are then measured to determine the relative amounts of different protein types.

Common Uses

This test is primarily used to diagnose conditions affecting protein synthesis or breakdown, such as liver disease (e.g., cirrhosis), kidney disease, or certain autoimmune disorders. It may also be part of a broader evaluation for nutritional deficiencies or inflammatory processes.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms like unexplained weight loss, fatigue, swelling, or if they suspect liver, kidney, or immune system issues. It’s sometimes included in routine evaluations for patients with chronic conditions.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal results may indicate hypoalbuminemia (low albumin levels), which can be linked to malnutrition, liver disease, or kidney problems. Elevated globulin levels might suggest chronic inflammation, infections, or autoimmune diseases. These findings guide further medical evaluation and treatment planning.

Frequently asked questions

What does a low protein result mean?
A low protein result may signal conditions like liver disease, kidney failure, or malnutrition. Your doctor will review your symptoms and other test results to determine the cause and next steps.
How long does it take to get results?
Results are typically available within 1 to 3 business days, depending on lab processing times. Your healthcare provider will contact you once they are ready to discuss the findings.
Is this test painful?
The blood draw for this test is generally mild discomfort for a few seconds, similar to a routine blood test. Most people experience minimal pain afterward. Ice or a warm compress can help reduce any soreness.
