If the test result suggests < 500 IU/mL, < 2500 copies/mL, or < ULN, the patient can be enrolled. Patients with HBV-DNA detected must agree to receive treatment with anti-HBV nucleos(t)ide analogues during the study. Patients who test positive for HCV antibody must further undergo HCV-RNA testing. If the test result suggests < ULN, the patient can be enrolled.
