[11, 17], Serologic testing for HBsAg is the primary screening test. In health-related fields, a reference range or reference interval is the range or the interval of values that is deemed normal for a physiologic measurement in healthy persons (for example, the amount of creatinine in the blood, or the partial pressure of oxygen). [26] (Open Table in a new window), Intermittently or persistently or =20,000 IU/mL, With recent advances in HBV treatment, including new potent antiviral agents and early detection of hepatocellular carcinoma through effective screening methods, prompt identification of persons with HBV infection allows the possibility of reducing morbidity and mortally.
