[Automatic complement fixation reaction applied to the diagnosis of influenza (author's transl)]. 1976

P Coursaget, and P Maupas, and G Larbaigt, and B Raynaud, and B Grenier

Auto-analysis has been adapted to the study of complement fixation on flu antigen-antibody complexes. The antigen used consists of a complete virus of strain A2/AICHI/68/H3N2 (antigen of envelope V). The advantages of this method reside in the reproducibility of the results and in instrumental reading with graphic recording and conservation of a graphical result. The recording of the percentage of hemolysis given by the auto-analyser permits calculation of the rate of the reaction K37 of complement fixation on the formed immune complex. This value is independent of temperature, time of fixation and the initial quantity of complement used. It is proportional to the quantity of specific antibody. Thus, the value of K37 is proposed as mode of expression of the results replacing the limit serum dilution.

UI MeSH Term Description Entries
D007251 Influenza, Human An acute viral infection in humans involving the respiratory tract. It is marked by inflammation of the NASAL MUCOSA; the PHARYNX; and conjunctiva, and by headache and severe, often generalized, myalgia. Grippe,Human Flu,Human Influenza,Influenza in Humans,Influenza,Flu, Human,Human Influenzas,Influenza in Human,Influenzas,Influenzas, Human
D007700 Kinetics The rate dynamics in chemical or physical systems.
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.
