Serodiagnosis of influenza by indirect haemagglutination test.
Results of studies on serodiagnosis of influenza A and B by the indirect haemagglutination test (IHA) with lyophilized erythrocyte diagnostic preparations, highly stable upon storage, are presented. The diagnostic value of the IHA test was in good agreement with, that of virus neutralization tests.
