Relationship between RDT and filter paper derived antibody titres to malaria antigens. Anti-MSP-11–19 and apical membrane antigen (AMA)-1 titres in attendees at eight health-care facilities in North-eastern Tanzania were determined using RDTs and compared to data from matched filter-paper blood spots [11]. Anti- MSP-11–19 (A) and AMA-1 (B) titres determined using filter paper (FP) blood-spots and RDTs were closely correlated (R2 = 0.65 for MSP-119, R2 = 0.73 for AMA-1). Panels C and D show the distribution of differences between RDT and filter paper titres for MSP-119 and AMA-1 respectively.
