HDGFL2 and malaria: Today there is only one commercial multiplexed assay for malaria antigen quantification, which is a planar array-based platform (the Q-Plex technology) and detects five biomarkers: HRP2, pan-specific pLDH (PanLDH), P. falciparum–specific pLDH (PfLDH), P. vivax–specific pLDH (PvLDH), and C-reactive protein (CRP) in whole blood and DBS [9, 10].
