[The use of hemagglutination inhibition tests and complement fixation tests for evaluation of immunity states and diagnosis of recent rubella infections]. 1975

E Măgureanu, and M Grobnicu, and D Botez

Comparative HAI and CF study of German measles antibodies in 575 sera collected from subjects of different age gave positive HAI reactions in 87% of the cases and positive CF reactions in 55% of the cases. The greater sensitivity of HAI and the longer presence of these antibodies justifies the use of this test for investigating the state of immunity in German measles. The combined use of the two tests for the diagnosis of the disease is very useful especially when the first serum sample is collected some time after the onset when the increase in serum antibody titers can only be demonstrated by CF, as HAI antibodies reach a high titer soon after the onset.

UI MeSH Term Description Entries
D003168 Complement Fixation Tests Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.

D006385 Hemagglutination Inhibition Tests Serologic tests in which a known quantity of antigen is added to the serum prior to the addition of a red cell suspension. Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of hemagglutination.
