Comparison of the Alere Pf Malaria Ag histidine-rich protein 2 rapid diagnostic test, CareStart rapid diagnostic test, and microscopy for diagnosis of clinical and asymptomatic malaria in a clinic

Population categories	Number sampled	Diagnostic test methods*
		Microscopy positive, % (n/N)	CareStart positive, % (n/N)	Alere positive, % (n/N)
Clinic visits (symptomatic)	475	40.6 (193/475)	53.5 (254/475)	55.2 (262/475)
Breastfeeding mothers (asymptomatic)	127	4.7 (6/127)	7.1 (9/127)	11.0 (14/127)
Breastfeeding children (asymptomatic)	123	ND	7.3 (9/123)	7.3 (9/123)

% = percent; n = number positive; N = number sampled; ND = not done.

^*Differences in malaria prevalence estimates for the different diagnostic methods are as follows: Clinic visits: CareStart versus microscopy, P = 0.0001; CareStart versus Alere, P = 0.599; Alere versus microscopy, P < 0.0001. Breastfeeding mothers: Microscopy versus CareStart, P = 0.418; CareStart versus Alere, P = 0.279; microscopy versus Alere, P = 0.063. Breastfeeding children: CareStart versus Alere, P = 1.000.
