An evaluation of the Technicon Autoanalyzer for automating complement-fixation tests. 1968

C E Taylor, and J W Kershaw, and G V Heimer

Obviously there is need for a reliable means of automating complement-fixation tests. This paper offers an account of experience with an AutoAnalyzer adapted for this purpose. Results of syphilis screening tests done by the AutoAnalyzer compared with those of tests performed manually showed satisfactory agreement, the automated method being slightly less specific in our hands. There were no false negative results with the AutoAnalyzer if both Maltaner and Reiter protein antigens were used. The current design of the AutoAnalyzer contains three major shortcomings if it is to be used for large numbers of complement-fixation tests. First and foremost is the relatively slow sampling rate compatible with adequate sample discrimination. Second is the necessity for frequently replenishing the machine with samples. Third is the need for adjusting or cleaning the flow-cell during use.

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.
