What is a Hep B titer? A Hep B titer generally refers to a special test known as the Hepatitis B Surface Antibody test. The Hep B test is frequently used to check the blood for evidence of immunity to Hepatitis B. It is not a shot or vaccination and the analysis needs to be performed by a laboratory.
Titer will not be performed. Negative: Titers equal to or less than 1:20. Titers greater than 1:20 may be present in acute viral hepatitis, lupoid hepatitis, infectious mononucleosis, and malignancy. Titer equal to or greater than 1:80 highly suggestive of chronic active hepatitis.
