What is high HBsAg level?
High levels of HBsAg are suggestive of low fibrosis and immune tolerance in hepatitis B e antigen (HBeAg) positive patients; whereas low levels of HBsAg indicate a lower risk for HCC and inactive carrier state in HBeAg negative patients.
What does HBsAg seroconversion mean?
The development of antibodies against HBsAg is known as HBsAg seroconversion. It signifies clearance of HBsAg and resolution of the chronic infection.
What is the meaning of HBsAg negative?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months.

What is the HBsAg confirmatory assay?
Intended Use The ADVIA Centaur HBsAg Confirmatory Assay is an in vitro diagnostic immunoassay for the qualitative confirmation of the presence of hepatitis B surface antigen (HBsAg) in human serum and plasma (potassium EDTA, lithium or sodium heparin) using the ADVIA Centaur system.
What is the prognosis of HBsAg positive or negative?
The titre of HBsAg in the serum rapidly declines during the first 6 weeks after the onset of illness; it is even possible for a patient with acute hepatitis B to have a negative serum HBsAg test result after only a few days of jaundice due to the rapid clearing of the antigen from the blood.
