Why Is This Test Done?

Doctors may order this test to check for liver disease, protein deficiencies, or other conditions affecting protein synthesis. It can also help monitor treatment responses in certain conditions.

What Does the Test Measure?

Bromocresol green is a dye that binds to proteins in your blood, particularly albumin. Lower levels may indicate problems with protein production, such as liver issues or malnutrition.

How Is the Test Performed?

A blood sample is taken from a vein, usually in your arm. The sample is processed to measure how much bromocresol green it can bind, reflecting protein levels.

What Are Possible Results?

Results are compared to a reference range, though exact values may vary by lab. Lower than expected levels may suggest liver disease, kidney problems, or other conditions affecting protein production.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a low BCG binding capacity mean?
A low result may indicate problems with your liver’s ability to produce proteins, such as albumin, which could be due to liver disease, kidney issues, or malnutrition. Your doctor will discuss next steps based on your overall health and test results.
How often should I get this test?
Your doctor will determine how often you need this test based on your medical condition. Some people may need it yearly, while others may require it more frequently if they have ongoing health concerns.
Can diet affect this test?
Yes, certain diets high in protein or liver-specific nutrients may influence protein levels in your blood. Your doctor may recommend dietary adjustments or further testing if needed, especially if you have liver-related conditions.
