Analyses for agreement of results by the various test formats.

Patient classification			Kappa test
			Kappa	value
MB	NDO-LID versus ELISA^1 with	LID-1	—	—
		NDO-BSA	0.643	<0.01
		ND-O-LID	1.000	<0.01
PB		LID-1	0.068	ns^3
		NDO-BSA	0.154	ns

¹ELISA was determined as positive if mean OD of duplicate wells was >2 × EC mean OD.
²WBA were determined as positive if IFN concentration was >50 pg/mL.
³ns, not significant.
