The conversion factor ranges between one and five HCV RNA copies per IU. Serum fibromarkers include APRI FIB-4 hyaluronic acid Fibrometer Fibrotest Forns Hepascore and other indices recently more complex tests such as Fibrometer Fibrotest and Hepascore have shown more accuracy in predicting liver fibrosis than simple biochemical tests such as APRI FIB-4 or Forns. Patients with positive anti-LKM or -ANA with homogeneous pattern should be evaluated for concurrent autoimmune hepatitis especially in the presence of ALT elevation while on treatment.
