Three RDTs, Malaria Pf/Pv Antigen Test AMFV-7025, Carestart Malaria Pf/Pv (HRP2/pLDH) Ag combo G0161 and Palutop 4+ Optima, specifically identified P. vivax (one specific band on RDTs) due to the detection of PvLDH (sensitivities from 83.5% to 91.9%) but were not more efficient at detecting P. vivax parasites than pLDH-based RDTs. The gene discussed is HDGFL2; the disease is malaria.
