did you test for hbsab? Read below for the diff blood test to check if you are 100% hep b positive. If you are hep b chronic, then you need to check for hep B dna. I suggest you check right away since you are 7 months pregnant. Talk to your doctor about hepatitis b immunization for your child. This will be a very important decision you make for your child. A baby has less than 10% chance to clear the virus w/o the immunization shot. There is no need in this time and age to not have immunization for the child. Make sure the child receives the immunization right away after birth. The sooner the better. First shot usually has to be before a 2 hour time frame.
HBsAg (hepatitis B surface antigen) - This refers to the outer surface of the hepatitis B virus that triggers an antibody response. A "positive" or "reactive" HBsAg test result means that the person is infected with the hepatitis B virus. This can be an "acute" or a "chronic" infection. Infected people can pass the virus on to others through their blood.
HBsAb or anti-HBs (hepatitis B surface antibody) - This refers to the protective antibody that is produced in response to an infection. It appears when a person has recovered from an acute infection and cleared the virus (usually within six months) or responded successfully to the hepatitis B vaccine shots. A "positive" or "reactive" HBsAb (or anti-HBs) test result indicates that a person is "immune" to any future hepatitis B infection and is no longer contagious. This test is not routinely included in blood bank screenings.
HBcAb or anti-HBc (hepatitis B core antibody) - This refers to an antibody that is produced in response to the core-antigen, a component of the hepatitis B virus. However, this is not a protective antibody. In fact, it is usually present in those chronically infected with hepatitis B. A "positive" or "reactive" HBcAb (or anti-HBc) test result indicates a past or present infection, but it could also be a false positive. The interpretation of this test result depends on the first two test results. Its appearance with the protective surface antibody (positive HBsAb or anti-HBs) indicates prior infection and recovery. For chronically infected persons, it will usually appear with the virus (positive HbsAg).
