TABLE 3.

Detection of HIV LTR and RNase P DNA using DBS from seropositive and seronegative persons residing in the United States

HIV sero-status (nd)	HIV-1 DNA detectiona		CT rangeb
	No. (%) positive	No. (%) negative	HIV LTR	RNase P
Positive (103)	101 (98.1)	2 (1.9)	28.6-39.95 (36.04 ± 2.06)	20.55-31.46 (25.99 ± 2.49)
Negative (56)	0 (0)	56 (100)	NAc	20.58-28.07 (23.52 ± 2.22)

^aSensitivity, 98.1% (95% CI, 95.5 to 100%); specificity, 100% (95% CI, 99% to 100%).

^bThe C_T values of 2 HIV PCR-negative samples were not included in the HIV LTR range, average, and 1-standard-deviation calculations. However, their respective RNase P C_T values were included in the RNase P column. Average and one standard deviation are given in parentheses.

^cNA, not applicable.

^dNo. of samples.
