  1. IFAT was considered as the reference standard: sensitivity was assessed in comparison to IFAT positive samples (N = 56) and specificity on IFAT negative samples (N = 8). Since samples with ELISA indexes falling in the “grey zone” were excluded from the analysis, the number of samples included for each test was as follows: BioRad n = 64; Dia.Pro n = 61; Euroimmun n = 60; Novatec n = 63; DRG n = 62
