Comparison of three serological kits for detecting antibodies against alphaherpesvirus in reindeer by the ranks of the results. The comparison of the kits two by two was done by plotting ranks after sorting the results (OD values for Kit A and competition percentage for Kit B and C) in ascending order. Results were given a rank position: 1^st rank being the most negative and 154^th rank the most positive. The graphs display the rank obtained per animal in each kit. Lines pass through the rank closest to the cut-off values for each kit (Kit A cut off value 0; Kits B and C lower cut off value 45%; Kit B higher cut off value 60%; Kit C higher cut off value 50%). For Kit A, a line (—) passes through the 92^nd rank (-0.031). For Kit B, a line (···) passes through the 88^th rank (47.28%) and another (— —) passes through the 90^th rank (59.60%). For Kit C, a line (— – —) passes through the 91^st rank (45.54%) and represents both cut-off values (higher and lower) as no samples were ranked in between. 2A: scatter plot displays Kit A and Kit B correlation. 2B: scatter plot displays Kit A and Kit C correlation. 2C: scatter plot displays Kit B and Kit C correlation.
