Answer

Prior to the initiation of ART, all patients who test positive for hepatitis B surface antigen (HBsAg) should be tested for HBV deoxyribonucleic acid (DNA) using a quantitative assay to determine the level of HBV replication. [6]

Chronic HBV is defined as testing positive for HBsAg for more than 6 months [10] ; patients with chronic HBV infection already receiving ART active against HBV should undergo quantitative HBV DNA testing every 6-12 months. [6]
