A positive or "reactive" result on the HBsAb test means that you're immune to the hepatitis B virus. A negative or "non-reactive" result means that you're not immune to the virus. This article explains what the hepatitis B surface antibody test is for, when it is used, and how the ...
be a window in which neither antibody nor antigen is detectable. 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 ...
The presence of hepatitis B core IgG antibody (HBcAb) by itself is not adequate to confirm clearing of HBV, nor is it protective against the disease and its sequelae. Thus, persons who are HBcAb positive, HBsAb negative, and HBsAg negative should not be considered immune to HBV infection. ...
Nonreactive (negative). This means you're not currently infected with hep C. If you think you've been exposed within the last 6 months, you will need to be tested again to make sure because it can take a while for your antibody levels to rise high enough to be detected on a test. ...

What is a Surface Antibody Titer? This is the blood test that checks for immunity to Hepatitis B. A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis...
The blood will be tested to determine how well the liver is functioning. A test will be ordered to detect antibody to hepatitis A. The results of this test will also determine if the patient has been recently exposed to HAV. Blood probably will be tested for the hepatitis B and hepatitis...

Testing for antibody to HCV is normally carried out as a two stage procedure. An ELISA format is used for initial testing of serum or plasma from patients or blood donors. Repeatedly reactive samples are then re-tested by a second ELISA in a different format or by a supplementary assay such...
Hepatitis E virus (HEV), a non-enveloped, positive-sense, single-stranded RNA virus, is a major cause of enteric hepatitis. Classified into the family Hepeviridae, HEV comprises four genotypes (genotypes 1-4), which belong to a single serotype. We describe a monoclonal antibody (mAb), 8G12...
