A new radioimmunoassay for demonstrating the antibody to hepatitis-B-surface-antigen(HBs-Ag).
A new radioimmunological system for demonstrating the antibody to hepatitis-B-surface-antigen (HBS-Ag) based on the immunoadsorption principle is described. The optimal conditions for the test are given. False-negative and false-positive results could be excluded by specificity tests on sera from 100 voluntary blood donors. The sensitivity of the system is comparable to that of other more expensive radioimmunological methods.
