Titration of antibodies to tetanus toxoid by agglutination of purified tetanus toxoid sensitized latex particles.
The method of sensitized latex particle agglutination which we have devised allows the selection of samples of plasma for the preparation of immunoglobulins. The population of thus selected samples is the same as is selected by the in vivo test, having a titer greater than or equeal to 6 IU/ml. The test gives a clear-cut difference between the positive and negative results and does not give any prozone phenomenon. It can be used extensively, as the batches of sensitized latex particles may be stored for quite a long time.
