Development and evaluation of a bead-based Multiplexed Fluorescent ImmunoAssay (MFIA) for detection of antibodies to Salmonella enterica serogroup B and C1 in pigs

Table 2 The risk of false positive results in MFIA in herds classified as Salmonella-infected and non-infected

		MFIA result for pigs that are negative in mix ELISA		Total	Risk of MFIA “false” positive results (%)
		Salmonella positive pigs in MFIA	Salmonella negative pigs in MFIA
Herd classification	Infected	74	576	650	11.38
Herd classification	Non-infected	4	587	591	0.68

Data comprise only pigs classified as negative based on mix ELISA. The relative risk (11.38/0.68) is 16.82
