What This Test Measures
This test includes two key components: Bromocresol Green (BCG) and Bromocresol Purple (BCP) assays. These tests evaluate the liver’s ability to process and detoxify substances, indirectly reflecting protein synthesis and metabolic function. While not a single enzyme, they collectively provide insight into liver function by measuring the concentration of certain substances in your blood.
Why It Matters
Liver function is critical for breaking down toxins, producing bile, and synthesizing proteins. Abnormal results may signal conditions like hepatitis, cirrhosis, or other liver diseases. Early detection can guide treatment and prevent complications.
Common Conditions Detected
This test is often used to screen for liver-related issues, such as chronic hepatitis, fatty liver disease, or bile duct obstructions. It may also help monitor liver function in patients with known liver conditions or those on medications that affect the liver.
Sample Collection and Preparation
A small blood sample is drawn from your arm. The test uses serum or plasma to analyze the specific substances measured by BCG and BCP. No special preparation is needed, but fasting may be advised depending on the clinical context.
Clinical interpretation
