TABLE 2.

Sensitivity of the NASBA assays for each dengue virus serotype compared with the C6/36 cell culture assay^a

Serotype	No. of samples positive by:		% Sensitivityb
	NASBA assay	C6/36 assay
Dengue-1	30	30	100
Dengue-2	10	10	100
Dengue-3	22	23	95.7
Dengue-4	4	4	100
Total	66	67	98.5

^aAliquots of samples were isolated simultaneously by the C6/36 cell culture assay and the NASBA assay. 

^bThe sensitivity for each serotype-specific or group-specific NASBA assay equals the number of test samples that were positive by the NABSA assay divided by the number of test samples that were positive by the standard culture assay in C6/36 cells.
