[A modification of the passive hemagglutination inhibition test to correct the results of the passive hemagglutination test in titrating tetanus antitoxin].

The aim of this work was to accelerate passive hemagglutination inhibition test, simplify it, perform it without an incubator and antibody diagnostic agent, and confirm the results of this test the characteristics permitting not only specific, but quantitative assessment of the results of passive hemagglutination test. To achieve this, the authors suggest the following modifications: the working dose of purified tetanus antitoxin is titered in relation to the standard serum; antibody erythrocytic diagnostic agent is modified by adding the working dose of purified tetanus antitoxin; the test is performed at room temperature.
