Table 3 Malaria prevalence rates during the dry season from the Tanintharyi Region of Myanmar comparing preserved capillary blood to dried blood spots (DBS), using Qiagen extraction method and new extraction method (NEM), respectively (n = 1739)

From: A novel method for extracting nucleic acids from dried blood spots for ultrasensitive detection of low-density Plasmodium falciparum and Plasmodium vivax infections

Species Blood/Qiagen DBS/NEM Kappa (95% CI)
Pf (%) 1.1 1.2 0.85 (0.73–0.97)
Pv (%) 5.9 5.3 0.86 (0.81–0.92)
Mixed (%) 0.3 0.1 0.57 (0.13–1.0)
  1. Pf, Plasmodium falciparum monoinfection; Pv, P. vivax monoinfection; Mixed, Mixed Pf and Pv; DBS, Whatman 3MM dried blood spot; NEM, new extraction method; 95% CI, 95% confidence interval
