What is the normal range for hepatitis B surface antibody?
For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
What is hepatitis B surface antibody anti-HBs?
HBsAg is the antigen used to make hepatitis B vaccine. Hepatitis B surface antibody (anti-HBs): The presence of anti-HBs is generally interpreted as indicating recovery and immunity from hepatitis B virus infection. Anti-HBs also develops in a person who has been successfully vaccinated against hepatitis B.
How are hepatitis B surface antibody anti-HBs results interpreted?
HBsAg is the antigen used to make Hepatitis B vaccine. Hepatitis B surface antibody (anti-HBs): The presence of anti-HBs is generally interpreted as indicating recovery and immunity from HBV infection. Anti-HBs also develops in a person who has been successfully vaccinated against hepatitis B.
What does it mean if your hepatitis B surface antibody is positive?
(antibody to hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is immune to hepatitis B infec- tion, either from vaccination or from past infection.
Labs usually measure down to less than 200 IU/mL. Below the threshold, the viral load is considered “undetectable” – something everyone with chronic hepatitis B wants to hear.
A viral load of > 10 000 copies/mL (2000 IU/mL) is a strong risk predictor of HCC, independent of HBeAg status, ALT level and liver cirrhosis[10,21,22].
What is the difference between hepatitis B surface antibody and antigen?
The basic blood test for hepatitis B consists of three screening tests: a hepatitis B surface antigen test, which determines whether a person currently has the infection; a hepatitis B core antibody test, which determines whether a person has ever been infected; and a hepatitis B surface antibody test, which determines …
What does hep B surface non reactive mean?
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.
