Diagram illustrating 9 separate experiments and the course of treatment with copper chloride before blinded diagnostic evaluation by 3 distinct devices; quantitative, and 2 qualitative tests, the CareStart G6PD (CSG) and fluorescent spot test (FST). The representations of tubes under donor blood indicate experiments on different days. The tubes showing CuCl treatments from 0 to 1.0 mM (top) represent a set of 5 replicates each for each separate experiment (#1–#6). The tubes showing %CuCl treated from 1% to 100% (bottom) each represent a set of triplicates for each of the experiments conducted (#7–#9).
