Characteristics of HIV-infected case subjects whose specimens were OraQuick false negative and control subjects whose specimens were OraQuick reactive^a

Characteristic	OraQuick false negative (n = 4)	OraQuick reactive (n = 20)	Pb
Age (yr)	31.7 ± 2.2	38.9 ± 9.8	0.16
Gender (% male)	75	85	0.54
Race (% white)	75	55	0.40
Seroconverters (%)c	75	60	1.000
Time since HIV Dx (yr)	3.08 ± 1.7	6.85 ± 3.99	0.081
CD4 count (cells/mm3)	540 ± 171	450 ± 275	0.54
VL (copies/ml)	<50	623.9d	0.034
HAART
Ever treated (%)	100	85	1.00
Duration (yr) (n = 17)	2.8 ± 1.3	1.9 ± 1.5	0.69
Duration/time positive (n = 17)	0.92 ± 0.084	0.45 ± 0.25	0.002
Time elapsed from Dx to HAART (yr) (n = 17)	0.31 ± 0.48	3.52 ± 3.30	0.025

^aFor age, time since HIV diagnosis (Dx), CD4 count, HAART duration, HAART duration/time positive, and time from diagnosis to HAART, values are shown as means ± standard deviations. For VL, values are shown as geometric means.

^bThe Fisher exact test (two-tailed) was used for treatment with HAART, gender, and seroconverters; the t test (two-tailed) was used for age, time since HIV diagnosis, CD4 count, HAART duration, and HAART duration/time positive; and the Mann-Whitney test (two-tailed) was used for race, VL, and time elapsed from diagnosis to HAART.

^cSeroconverters were defined as patients with known prior negative HIV-1 serology.

^dMedian value, 199; interquartile range, 9,136.
