Assessment of Successful qRT-PCR of SARS-CoV-2 Assay in Pool Screening Using Isopropyl Alcohol Purification Step in RNA Extraction

Table 2

Sensitivity and specificity performance of RNA purification in SARS-CoV-2 assay.

RT-PCR	RNA purification
	Positive	Negative	Total
Positive	85 (TP)	15 (FN)	100
Negative	0 (FP)	400 (TN)	400
Total	85	415	500

PPV: positive predictive values; NPV: negative predictive values; (PPV) positive predictive value: ; (NNV) negative predictive value: ; TP: true positive; FN: false negative; FP: false positive; TN: true negative.
