Information

Immunoassay for the in vitro qualitative detection of hepatitis B surface antigen (HBsAg) in human adult serum and plasma. Assay results, in conjunction with other serological and clinical information, may be used for the laboratory diagnosis of individuals at risk for infection with HBV or with signs and symptoms of hepatitis. In addition, this assay may be used to screen for hepatitis B infection in pregnant women to identify neonates at high risk of acquiring HBV during the perinatal period.

Collection Information

Methodology

Electrochemiluminescence-immunoassay (ECLIA)

Limitations

Current methods for the detection of HBsAg may not detect all infected individuals. A negative test result does not exclude with certainty a possible exposure to or an infection with the hepatitis B virus. Negative test results obtained for persons with a past exposure may be caused by an antigen concentration below the detection limit of this assay or the lack of reactivity of the antigens to the antibodies used in this assay.
