Hepatitis Bserologyinterpretationimmune statusanti-HBsMedical laboratory scientists who had agreed to participate in an evaluation which required them to measure the level of anti-HBs in a panel of sera, were given a brief clinical scenario for seven of the results and asked to comment on the ...
The hepatitis B surface antibody test (HBsAb) detects proteins that are made by the immune system (antibodies) in response to thehepatitis B virus (HBV). The test is used to find out if you areimmuneto the virus after natural exposure or vaccination. You have to give a blood sample for ...
Consequently, another test is required to ensure diagnosis. This is to detect the presence of immunoglobulin M (IgM) antibody directed against the core antigen (IgM anti-HBc), which is the earliest discernible anti–hepatitis B antibody. The presence of HBeAg implies high infectivity; it is ...

bDefined by a positive HBsAg result. Chronic HBV infection should be staged by assessment for hepatitis fibrosis/inflammation, HBV viral load, HBeAg status, antibody to HBeAg (anti-HBe) status, and liver function test results. Appropriate interventions depend on disease stage. cDefined as positive...

The textual interpretation is sent back via e-mail. Each qualitative test for hepatitis A and B antibodies and antigens may produce one of four possible results: positive, negative, borderline, and not tested. To cover the resulting 64 (A) and 57344 (B) combinations of findings, the ...
Interpretation of Results: Positive: Both purplish red test band and purplish red control band appear on the membrane.The lower the antibody concentration,the weaker the test band. Negative: Only the purplish red control band appears on the membrane.The abse...
