Comparison of results of viral culture and IF and those of multiplex RT-PCR-EHA methods for detection of respiratory viruses^a

RT-PCR-EHA/ VC-IF resultb	No. of specimens with indicated results
	HPIV-1	HPIV-2	HPIV-3	Inf Ac	Inf Bd	RSV
+/+	0	0	0	6	1	1e

^aA total of 143 clinical specimens were screened for each respiratory virus. 

^bVC, viral culture. The four possible combinations of RT-PCR-EHA and viral culture-IF results are listed. +, positive result; −, negative result. 

^cInf A, influenza virus type A. 

^dInf B, influenza virus type B. 

^eThe subtype was not defined by viral culture or IF. However, the sample was RSV type A and B positive by RT-PCR-EHA.
