Positive and negative agreement of the Taiwan CDC lab-developed SARS-CoV-2 assay with the BD MAX platform SARS-CoV-2 assay.

		Lab-developed assay		BD MAX platform
		E gene	RdRp gene	N1 gene	N3 gene
Total Positives*		55		55
Ct Value	Low (> 30)	3	11	10	14
	Medium (20–30)	45	41	44	40
	High (< 20)	7	3	1	1
Total Negative#		150		150

* Positive result interpretation: Both E and RdRp genes were detected or both N1 and N3 genes were detected.

^#Negative result interpretation: none of E or RdRp genes was detected or none of N1 or N3 genes was detected.
