--- Hemagglutination Inhibition (IH) and Enzyme-linked Immunosorbent Assay (ELISA) Serological tests are routinely used for antibodies detection against the virus of Newcastle disease (NDV). Antigen for IH test may be a strain of respiratory tropism or enteric tropism. This study analyzed the concordance between the HI and ELISA tests. For this purpose, the serological results obtained on 196 sera collected in broilers of 26 and 42 days old were analyzed, before and after being challenged with a velogenic viscerotropic strain of newcastle disease virus. The antibodies detected by both tests were grouped into four scales according to their detection level (negative, low, medium and high) in order to later be analyzed by the Kappa Cohen statistic test. Concordance between the two tests of IH with respiratory or enteric antigen was analyzed, and concordance between each these (IH respiratory and IH enteric) with the ELISA test was analyzed. It was found that the concordance between IH test and ELISA, using both enteric antigen and respiratory antigen was very poor, while the concordance between the two IH tests (respiratory or enteric antigen) was moderate. Keywords: virus Newcastle disease (NDV), ELISA, HI, kappa index, concordance.
