Results of RT-PCR and culture for various specimens from the patient

Specimen	Conventional RT-PCR resulta	Real-time RT-PCR resultb	Culture resultc
Serum sample	+	Undet	C1V1
NPS swab (first swab)	Undetd	Undet	Undet
NPS swab (second swab)	Undet	Undet	Undet
Nasal swab	+	36.4	C1V2
Pharyngeal swab	+	39.5	Undet

^aA + sign indicates that a band of the expected size was obtained in the conventional RT-PCR assay.

^bThe numbers are the threshold cycle values obtained in the reaction. In this particular assay, values below 45 are positive.

^cC1V1 is CPE first observed on or after one C6/36 cell passage and one Vero cell passage, and C1V2 is after one C6/36 cell passage and two Vero cell passages.

^dUndet, undetected.
