What is a normal hepatitis B titer?
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.
Should my hep B titer be positive or negative?
If your HBsAb is positive, it either means you’ve been infected in the past or received the vaccine and are now immune. You cannot infect others and do not require vaccination. If all three tests are negative—meaning that you have never been exposed to the virus—you will be advised to get the HBV vaccine.
How do you interpret HBsAg results?
A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood. anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus.
Should a Hep B titer be reactive or nonreactive?
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.
What does anti-HBs reactive mean?
■ Anti-HBs [sometimes written as HBsAb] (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.
What test do you order for hep B titer?
A Hepatitis B Surface Antibody Blood Test, Quantitative or HBsAB evaluates possible immunity in individuals who are at increased risks for exposure to Hepatitis B. Preparation: No special preparation required. Test Results: 2-3 days.
What is Anti-HBs Cmia?
Normal: Nonreactive. Comment. Specimens submitted for detection of antibody to HBV surface antigen (Anti-HBs) are tested using a chemiluminescent microparticle immunoassay (CMIA) that detects IgG anti-HBs. This automated assay on the Abbott Architect system provides a quantitative determination of Anti-HBs.
