Performance of the five ELISA kits for the qualitative classification of malaria patients serum samples compared to IFAT

	BioRad	Dia.Pro	Euroimmun	Novatec	DRG
%SE (95% CI)	53.6 (39.7–67)	64.2 (49.8–76.9)	56.6 (42.3–70.2)	54.5 (40.6–68)	55.6 (41.4–69.1)
%SP (95% CI)	100 (63.1–100)	100 (63.1–100)	100 (59–100)	100 (63.1–100)	100 (63.1–100)

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
