Consistent with theresults of HRP2 ELISA, persistent long-term HRP2 positivity in RDTs was highlycorrelated with initial parasitemia (Paracheck-Pf RDT SpearmanP < 0.001, correlation coefficient 0.6; BinaxNow T2band Spearman P = 0.001, correlation coefficient 0.6). Here, HDGFL2 is linked to parasitic infectious disease.
