Liver Fibrosis, FibroTest‑ActiTest Panel
Use
The FibroTest‑ActiTest Panel provides a non‑invasive evaluation of liver fibrosis (FibroTest) and inflammation (ActiTest), commonly used in patients with chronic hepatitis B or C, NAFLD, or other liver conditions to assess disease severity without requiring biopsy. FibroTest and ActiTest scores correlate to the Metavir staging system, facilitating treatment decisions and monitoring progression.
