Over the last years a number of lateral flow G6PD assays have been evaluated in field trials, including the CareStart G6PD RDT from CareStart (RoK) and the BinaxNOW G6PD Test from Binax (USA) [38, 39], both of which return binary results and only detect G6PD deficiency at the 30% G6PD activity threshold [38, 39]. Here, G6PD is linked to hyperinsulinemic hypoglycemia, familial, 4.
