Adu-Gyasi et al. [48] also reported 100 % sensitivity of the CareStartTM G6PD RDT for detecting G6PD deficiency from capillary blood of Ghanaian participants against Trinity Biotech quantitative G6PD assay; however, a cut-off activity of 75 % (equivalent to 4.1 U/gHb) was adopted for evaluation. Here, G6PD is linked to G6PD deficiency.
