Diagnostic accuracy of RDT for malaria infection by parasite density (dry season)

Parasite density		RDT Result
(/μL)	N	positive (n)	negative (n)	Sensitivity (95% CI)	Specificity (95% CI)
0	306	32	274		90
1-400	50	38	12	76
401-4000	28	27	1	96
4001-40000	11	11	0	100
40000+	5	5	0	100
Not infected	306	32	274		90 (86 - 92)
Infected	94	81	13	86 (78 - 92)
Total		113 (28%)	287 (72%)

PPV during dry season: 72% (95% CI: 63 - 79%), NPV during dry season: 95% (95% CI: 92 - 97%).
