[Development of an IHI test for detection of immunoglobulins of different classes]. / Razrabotka reaktsii RTNGA dlia obnaruzheniia immunoglobulinov razlichnykh klassov

ABSTRACT

The authors elaborated a method of obtaining stable erythrocytic diagnostic agent intended for titration of immunoglobulins A, M and G in the human blood serum by means of the indirect hemagglutination inhibition test (IHI). The suggested microdroplet method of conducting the IHI test permits to reveal (X +/- m) IgG--0.29 +/- 0.15 microng/ml, IgM--1.56 +/- 0.2 microng/ml, and IgA--0.16 +/- 0.07 microng/ml. The test is highly specific, simple and can be used in practical serological laboratories. The result is obtained in 2 1/2--3 hours.
