title: [Serological activity of incomplete antibodies].
abstract: Blood sera containing incomplete antibodies were studied in various serological tests, by the results of Coombs' and the inhibition of complement fixation tests. It was shown that division of antibodies into complete and incomplete by their serological activity was conditioned. Antibodies detected in Coombs' test could fix the complement. The blocking antibodies depressing the complement fixation test could fix the homologous complement. Proceeding from the latter the author suggests the test of the conglutinating complex fixation which proved to be effective in detection of antibodies inactive in the agglutination and complement fixation tests.
