One of these markers is the HBsAg. In 1964 Blumberg and col. were the first to detect an antigen in the blood of an Australian aborigine which reacted with the serum antibody of a New York haemophilia patient. This antigen was later identified as hepatitis B surface antigen. The discovery and identification of hepatitis B surface antigen was a great stride forward in the knowledge and differentiation of viral hepatitis infections. The presence of HBsAg in serum or plasma constitutes the most important indicator for the diagnosis of a hepatitis B virus (HBV) infection. The enzyme immunoassay was first described by Engvall and Perlmann and van Weemen and Schuurs in 1971. The technique was subsequently developed by Voller and col. using microplates, that permitted the development of highly sensitive and accurate diagnostic kits.;Species Reactivity:Virus;Application:qualitative;Storage:Unopened Kit: Store at 2 - 8°C.
