Performance characteristics of HIV RDTs

RDT	Sensitivity% (n = 150)		Specificity% (n = 150)
RDT	Manufacturer’s SEN^*	SEN^†	Manufacturer’s SPE^*	SPE (95% CI)^†	NPV% (95% CI)^†	PPV% (95% CI)^†
Determine	100	100	99.9	85.2 (77.4, 91.1)	100 (96.3, 100)	67.3 (52.9, 79.7)
STAT-PAK	100	100	100	99.1 (95.3, 99.9)	100 (96.8, 100)	97.2 (85.5, 99.9)
Uni-Gold	100	100	99.7	97.4 (92.6, 99.5)	100 (96.8, 100)	92.1 (78.6, 98.3)
First Response	100	100	99.2	97.4 (92.6, 99.5)	100 (96.8, 100)	92.1 (78.6, 98.3)
Advanced Quality	100	100	100	100 (96.8, 100)	100 (96.8, 100)	100 (90.0, 100)

PPV = positive predictive value; NPV = negative predictive value; CI = confidence interval; RDT = rapid diagnostic test; SEN = sensitivity; SPE = specificity

Manufacturers’ test characteristic performance (kit inserts) on serum; PPV and NPV dependent on the prevalence of population tested
