Negative results can also mean that the substance being tested for was present in a normal amount. The natural course of chronic HBV infection is also variable, ranging from an inactive carrier state to progressive chronic infection, which may evolve into cirrhosis and hepatocellular carcinoma. A false-negative test result may suggest that a person doesn't have a disease or condition being tested for when he or she does have it. For screening purposes in asymptomatic individuals when acute infection is not suspected, only HBsAg is adequate for the diagnosis of HBV infection.
