seen pavisa hepatitis b surface antigen by latexagglutination

摘要

A diagnostic composition for the detection of hepatitis B surface antigen in blood serum which comprises an aqueous suspension of finely divided synthetic resin particles of substantially uniform size coated with purified antibody specific to hepatitis B surface antigen is employed in a differentiating method where rheumatoid factor, which may cause nonspecific reactions, is absorbed with latex beads coated with human gamma globulin.
