Kim et al. [21] also reported lower CareStartTM G6PD RDT sensitivity of 68 % but higher specificity of 100 % for detecting G6PD deficiency in a field evaluation of the test among Cambodians at the lower limit of normal activity (a cut-off activity of 3.6 U/gHb) against the enzymatic assay. This evidence concerns the gene G6PD and hyperinsulinemic hypoglycemia, familial, 4.
