The purpose of the work was to carry out comparative analysis of the positive and negative on leukemia cattle blood sera in ELISA kits of different constructions. Research was carried out using “DIA®-BLV-Ab” kit, in which the reaction had been performed in the indirect ELISA, and “ID Screen® BLV Competition” kit in a competitive format. There were used 15 cattle blood sera for testing, in which antibodies to BLV were confirmed in the ID and the ELISA “Bovine leukemia virus antibody test kit” (IDEXX), as well as 10 positive cattle blood sera confirmed in ID, 10 weak positive sera tested in ID and 10 sera with a weak line of precipitate in ID, 34 negative for leukemia blood sera tested in ID, from which 24 were also tested in the ELISA “Bovine leukemia virus antibody test kit”. The “DIA®-BLV-Ab” kit and “ID Screen® BLV Competition” kit determined positive 25 blood sera with antibodies to BLV, which were positive in ID, and 15 samples were also confirmed in IDEXX test kit. When analyzing 10 sera, that were weak positive in ID, the “DIA®-BLV-Ab” kit determined 8 sera as positive and 2 samples as negative. The “ID Screen® BLV Competition” kit detected specific antibodies to all sera. When analyzing 14 sera with a weak precipitate line in ID, the “DIA®-BLV-Ab” kit determined 9 samples as positive and 5 as negative. The “ID Screen® BLV Competition” determined specific antibodies in 11 samples When analyzing 3 sera, the test result was negative in both ELISA kits. The “DIA®-BLV-Ab” kit determined as negative all 34 sera, which were negative in ID, 24 samples from them were negative in IDEXX test kit. In the “ID Screen® BLV Competition” kit 5 false positive results were received. Studies have shown that both test kits have a high diagnostic capacity and detect antibodies to BLV at different concentrations in all positive sera. The “DIA®-BLV-Ab” kit determined 34 sera as negative, in which specific antibodies were absent, and the “ID Screen® BLV Competition” kit identified 5 samples with a false positive result
