The authors state that the patient had a low G6PD enzymatic activity "The spectrophotometric assay showed a mildly reduced level of the enzyme: 7.2% (normal range: 8-18%)." Does 7.2% refer to the activity compared to a normal control? Could the authors specify the value expressed in international units per grams of hemoglobin (IU/gHb)? Could the authors explain this line "Though this X-linked disease is known to affect males exclusively, Errico et al., [2] have described it in females as well.", are they referring to G6PD deficiency or to hemolysis caused by ketoacidosis with G6PD deficient subjects?
