[Sensitivity and specificity of the passive hemagglutination reaction applied to titration of herpes antibodies].

52 human sera were checked for herpes virus hominis type 1 antibodies by passive hemagglutination, complement fixation, neutralization tests and plaque reduction in presence of complement. A good correlation was observed among the results obtained by the passive hemagglutination test and the plaque reduction in presence of complement. The rapidity of the indirect hemagglutination test and the sensitivity of the reaction are in favour of its routine use.
