Abstract
Sera from groups of hepatitis patients, renal transplant recipients, and from normal, healthy individuals were examined for the presence of hepatitis-associated antigen (HAA) by means of 3 different qualitative techniques: agar-gel diffusion, gel-electrophoresis, and a micro-complement fixation technique. Differences in the results obtained could be ascribed to differences in sensitivity of the tests employed and to differences in the amount of HAA present in the serum samples investigated, as measured by electrophoresis in antibody containing agar.
