The objective of this study was to measure the degree of concordance between the Indirect hemaglutination (HAI) and Indirect immunofluorescence (IFI) tests for Toxoplasma gondii detection in sheep. A total of 310 sera were collected from ewes of different ages at Fundo Santa María, district of Nuñoa, province of Melgar, Puno. The Kappa (K) value was 24%, showing that the degree of association between both techniques was of a regular type. The Mc Nemar test showed significative differences between both tests, so one cannot replace the other. The seroprevalence for T. gondii was 50.3 ± 5.6% through HAI test and 88.1 ± 3.5% through IFI test. Seroprevalence in animals <1, 1-2, 2-3, and >3 years of age was 23.2, 33.3, 52.1, and 58.7% through HAI test and 72.0, 90.0, 91.2, and 90.5% respectively through IFI test.
