Placental Plasmodium falciparum malaria infection: Operational accuracy of HRP2 rapid diagnostic tests in a malaria endemic setting

Table 2 Accuracy of peripheral blood RDTs in detecting malaria in pregnancy among 432 febrile women attending antenatal care at Mbale regional referral hospital between March and November 2010

Accuracy Parameter¶	Peripheral RDTs for symptomatic pregnant women(95% CI)
Sensitivity	96.8(92.3-98.8)
Specificity:	73.5(67.8-78.6)
Positive predictive value	68.0(61.4-73.9)
Negative predictive value	97.5(94.0-99.0)
Likelihood ratio
Positive LHR[W]	2.13(1.72-2.62)
Negative LHR [w]	0.03(0.01-0.06)

Test sensitivity = conditional probability that the test will be positive if the condition is present
Test specificity = conditional probability that the test will be negative if the condition is absent
W = weighted for prevalence
