A hepatitis B surface antigen (HBsAg) assay can be combined with other serological and clinical information to diagnose people suffering from acute or chronic hepatitis B infection. This assay may also be employed to screen for hepatitis B infection in the case of pregnant women to recognise neonates who are at risk of acquiring hepatitis B during the perinatal period.
If HBsAg screen is positive, HBsAg Neutralization Confirmatory test will be performed at additional cost.
