The AD surface antigen of the Hepatitis B virus (HBsAg) is a protein component of the viral envelope that is predominantly expressed in the cytoplasm of infected hepatocytes. HBsAg has antigenic heterogeneity; two pairs of the subtypes d/y and w/r lead to antigenic combinations of adw, ayw, adr, and ayr.
