title: [Indirect hemagglutination inhibition reactions as a method of titrating immune serums. V. Application of the reaction to the quantitative determination of immunoglobulins A, M and G in human blood sera].
abstract: The authors present the results of using the indirect hemagglutination inhibition test (IHIT) for quantitative determination of A, M and G immunoglobulins in the blood sera of humans in comparison with the method of radial immunodiffusion in agar (RID) after Mancini. The results of IHIT were no less precise and reproducible than those of RID. The significance of the correlation coefficient of grades after Spirman constituted greater than 99.9% for both tests. On this basis a conclusion was made that, having a number of advantages over RID, IHIT could be recommended for quantitative titration of immunoglobulins of various classes.
