“…It is reasonable, therefore, to treat patients with genotype 2 or 3 infection without performing a baseline liver biopsy if there is no evidence of advanced liver disease clinically, or by using noninvasive tests/ biomarkers. In those with genotype 1 or 4 infection, or where there is clinical concern regarding co-existent liver disease such as haemochromatosis, or alcohol-related or other liver disease, a biopsy can be helpful in staging the liver disease(s) and determining the need for HCV therapy [194][195][196][200][201][202]205,206]. In those individuals refusing liver biopsy, noninvasive tests/biomarkers such as hepatic elastography can be useful alternate techniques to identify those with earlier stages of fibrosis not requiring therapy (see General section).…”
