Staging systems (like METAVIR)

Staging systems, like METAVIR, are tools used by doctors to assess the extent of liver damage caused by conditions such as hepatitis. They evaluate the degree of fibrosis (scarring) and inflammation, helping to determine how advanced the disease is. The METAVIR system assigns scores from F0 (no scarring) to F4 (severe scarring or cirrhosis). This standardized staging guides treatment decisions and helps predict outcomes, providing a clear, structured way to monitor disease progression and tailor patient management effectively.
