The IMMY EIA and MV EIA were performed on all urine samples. Correlation and agreement between the assays were determined. Diagnostic performance was determined and compared between assays.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The IMMY EIA, with a 0.25\u2009ng\/mL diagnostic cutoff, provided a diagnostic sensitivity (DSe), diagnostic specificity (DSp), and diagnostic accuracy (DAc) of 89% (95% confidence interval [CI]; 73%-97%), 80% (67%-89%), and 83% (74%-90%), respectively. The IMMY EIA, with a 1.1\u2009ng\/mL diagnostic cutoff, provided a DSe, DSp, and DAc of 77% (95% CI 60%-90%), 97% (88%-100%), and 89% (81%-95%), respectively. The MV EIA provided a DSe, DSp, and DAc of 94% (95% CI 81%-99%), 97% (89%-100%), and 96% (90%-99%), respectively. Moderate overall agreement was found between MV EIA and IMMY EIA using the 0.25\u2009ng\/mL cut-off (\u043a\u2009=\u20090.44; 95% CI 0.31-0.57) and the 1.1\u2009ng\/mL cut-off (\u043a\u2009=\u20090.43, 95% CI, 0.31-0.56).<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Clinical Importance<\/jats:title>\n The IMMY EIA might be useful as a diagnostic test for histoplasmosis in cats. Further modifications of the IMMY EIA are required to achieve the diagnostic performance of the MV EIA.<\/jats:p>\n
