Comparison of the Real‐Q (BioSewoom) and DaAn Gene assays for the detection of SARS‐CoV‐2

Real‐Q 2019‐nCoV−2 (BioSewoom) (New Kit)	DaAn Gene SARS‐CoV2 (Non Reference Standard)		Total
	Positive	Negative
Positive	a (19)	b (0)	19
Negative	c (3)	d (22)	25
Total	a+c (22)	b+d (22)	44
Positive Percent Agreement (PPA) = 100% × a/(a+c) = 100% × 19/(19+3) = 86.4% Negative Percent Agreement (NPA) = 100% × d/(b+d) = 100% × 22/(22+0) = 100% Overall Percent Agreement (OPA) = 100% × (a+d)/(a+b+c+d) = 19+22/(19+0+3+22) = 93.2%
