Table 2.
Plasmodium falciparum samples with pfhrp2 or pfhrp3 deletion. Nine samples positive by three independent PCR assays, two of which target single-copy genes, were negative by PCR for pfhrp2 or pfhrp3. PCR outcome of the corresponding flanking regions are also shown. *Positive by qPCR with parasitaemia of 167 parasites per µL. Pfhrp2 and pfhrp3, Plasmodium falciparum histidine-rich protein 2 and 3 respectively; RDT, rapid diagnostic test; PF3D7_0831900 and PF3D7_0831700, upstream and downstream flanking regions of pfhrp2, PF3D7_1372100 and PF3D7_1372400, upstream and downstream flanking regions of pfhrp3.
