Glucose-6-Phosphate Dehydrogenase Deficiency and Sickle Cell Trait among Prospective Blood Donors: A Cross-Sectional Study in Berekum, Ghana

Figure 2

Comparison of red blood cell G6PD enzyme activity levels of blood donors. G6PD activities of red cells were measured using quantitative G6PD kit from Trinity Biotech and calculated against the donor haemoglobin levels. Statistical differences between G6PD enzyme activities were estimated using Kruskal-Wallis test with Dunn’s posttest for multiple comparisons. A: haemoglobin A; S: haemoglobin S; ND: no qualitative G6PD activity; FD: full qualitative G6PD defect; PD: partial qualitative G6PD defect (; ).
