Comparative analysis of NanoSpike- and NanoNuc-mediated hemagglutination tests.

	Nucleocapsid CIA (Abbott)		Spike ELISA (EUROIMMUN)		Positive percent agreement (%)	Negative percent agreement (%)
	Ig pos, n = 80	Ig neg, n = 108	Ig pos, n = 42	Ig neg, n = 40	Positive percent agreement (%)	Negative percent agreement (%)
NanoSpike			41	39	98	98
NanoNuc	59	106			74	98

Hemagglutination assays based on serum from COVID-19 convalescent and control patients was performed using NanoSpike and NanoNuc and directly compared to results obtained from the Nucleocapsid CIA (Abbot) and Spike ELISA (EUROIMMUN), respectively. Hemagglutination assay controls, i.e. NanoControl and NanoLink were included to aid visual test interpretation.
