FibroTest-ActiTest, Serum
Use
The FibroTest-ActiTest is utilized for evaluating hepatic fibrosis and inflammatory activity in patients with liver conditions such as chronic hepatitis C and B, HIV co-infection, and nonalcoholic fatty liver disease. It enables clinicians to assess the severity of hepatic fibrosis and necroinflammatory activity while providing access to treatment options for hepatitis. The test employs a combination of six serum biomarkers which provide a non-invasive alternative to liver biopsy, aiding in diagnosis and monitoring of liver fibrosis.
Special Instructions
Not provided.
Limitations
The FibroTest-ActiTest may produce inaccurate results in situations involving acute liver conditions, drug-induced enzyme changes, or when performed on patients under 2 years of age. Conditions such as acute hemolysis, hepatitis, inflammation, and specific drug interactions can alter the test's reliance on serum biomarkers. Elevated levels of individual biomarkers may signal caution or preclude accurate interpretation. The test is not suitable for patients under 2 years.
