Complement Fixation, Hemagglutination-Inhibition,and Trypsin Inhibitory Capacity Testing of Human Sera.

摘要

The overall objectives were to carry out 3,000complement fixation and hemagglutination-inhibition tests on human sera. The four antigens were: Flu A-2/Japan; Flu A-2/Hong Kong/68; Flu B/Maryland;and Flu B/Massachusetts. A total of 3,170serum samples were each tested with the four Flu antigens. In all tests performed,exactly 4units of each antigen were used and serum controls were satisfactory. All HAI results are tabulated as the reciprocal of the highest serum dilution which completely inhibited agglutination. The complement fixation (CF) test was performed utilizing Influenza Group A and B soluble antigens. A total of 3,063serum specimens were tested. All CF results are tablated together with the HAI results. (Author)
