23ConclusionConsidering non-invasive tests in HCV hepatitis, blood test and elastometry have the advantage to be independent methods.In case of discrepant results, two solutions:Another third examination like liver biopsyOr test combinationFor follow-up, certain blood test(s) could be more reproducible and more sensitive to detect small changes than other examinations.
