Glucose-6-Phosphate Dehydrogenase

This is a blood test used to determine how the body is metabolizing glucose. Glucose-6-phosphatedehydrogenase deficiency is often a trait that is carried on the X (male) chromosome. Males affected by this usually inherit the trait from their mothers. In these males, the disease which results is the most severe. In the case of a patient with this disease, certain drugs, such as antimalarials, sulfa, aspirin, phenacetin, antipyretics, quinidine, sulfonamides, thiazide diuretics, and tolbutamidecan cause red blood cell destruction, severe anemia, and infections.
