Abstract：
:The single radial haemolysis reaction has been shown to be suitable for the quantitative assay of specific antibody to West Nile and Sindbis viruses. Only 5 mul of undiluted serum are needed for the test, which can be performed on crude preparations of antigen and without removal of nonspecific inhibitors. It is therefore a very simple procedure. Moreover, it appears to be more specific than the classical haemagglutination-inhibition tests.
