Table 5 Diagnostic accuracy of RDT for malaria infection by parasite density (dry season)

From: Accuracy of a rapid diagnostic test on the diagnosis of malaria infection and of malaria - attributable fever during low and high transmission season in Burkina Faso

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