HBV Serology

I always mess up the order of appearence of the Antigens (Ag) and Antibodies (Ab) of the Hepatitis B Virus once it enters the body.

Actually is pretty simple. Just look at the fist picture.

  • You see that the outermost part of the virus is the surface, HBsAg
  • The one following it is the HBeAg, which is the extracellular form of the core protein.
  • And the innermost is the core protein, HBcAg

The order of appereance follows that direction “in & out”… And remember, first the Ag and then the Ab

  1. HBsAg
  2. HBeAg
  3. Anti-HBcAb
  4. Anti-HBeAb
  5. Anti-HBsAb
