Table 5 RDT percent test sensitivity by parasite density based on microscopy for Plasmodium falciparum and Plasmodium vivax
Parasite density in blood | Plasmodium falciparum | Plasmodium vivax | ||
|---|---|---|---|---|
n = RDT+/microscopy+ | Sn (%) | n = RDT+/microscopy+ | Sn (%) | |
1-100/μl | 3/5 | 60 | 3/14 | 21.4 |
101-1,000/μl | 14/18 | 77.8 | 13/25 | 52 |
1,001-10,000/μl | 33/34 | 97 | 42/42 | 100 |
10,001-100,000/μl | 31/31 | 100 | 4/4 | 100 |
Cut-off for 100% Sensitivity | 4,800 parasites/μl | 640 parasites/μl | ||
