[The immune response in those ill with and convalescing from Q fever studied by using immunoenzyme analysis]

The study of immune response in Q-fever patients and convalescents at different periods from the beginning of the disease demonstrated the diagnostic possibilities of the complement fixation test (CFT), the microagglutination test (MAT), the passive immunofluorescence test (PIFT) and the enzyme immunoassay (EIA). High effectiveness of EIA in comparison with CFT, MAT and PIFT was noted (97, 63, 87 and 91% respectively). The sensitivity of EIA was not less than 100-250 times higher than that of CFT, 15-100 times higher than that of MAT and 30-80 times higher than that of PIFT.
