An 18-year-old black male was suspected of having G6PD deficiency when he experienced hemolytic anemia after administration of primaquine. An erythrocyte G6PD analysis performed on blood taken 2 days after symptoms appeared was normal. A reticulocyte count revealed 12% reticulocytes at this time. These results suggest that: (Objective 7)
A) the patient definitely does not have G6PD deficiency but could have pyruvate kinase deficiency
B) another G6PD test should be done in several months when the reticulocyte count returns to normal
C) leukocytes could be contaminating the sample, giving a false result
D) the patient probably has the G6PD-Mediterranean variant
