Comparison of SARS-CoV-2 RT-qPCR–positive samples and positive rapid tests

PCR	Rapid test		Total
	Positive	negative
positive	8	14	22	Sens: 8/22 = 36.4% [17.2; 59.3]
negative	3	24	27	Spec: 24/27 = 88.9% [70.8; 97.7]
Total	11	38	49
	PPV: 8/11 = 72.7% [39.0; 94.0]	NPV: 24/38 = 63.2% [46.0; 78.2]

Weak and strong responses were counted as positive.

Sens: sensitivity; Spec: specificity; PPV: positive predictive value; NPV: negative predictive value; RT-qPCR: real-time quantitative polymerase chain reaction.

Square brackets give the 95% confidence intervals.
