GLUCOSE-6-PHOSPHATE DEHYDROGENASE

The glucose-6-phosphate dehydrogenase (G6PD) test measures the level of G6PD, an enzyme that helps protect red blood cells from damage, in the blood. This test is used to diagnose G6PD deficiency, a genetic disorder that can lead to hemolytic anemia. Individuals with G6PD deficiency are more susceptible to red blood cell destruction when exposed to certain triggers, such as infections, certain medications, or foods like fava beans. The G6PD test is valuable for identifying individuals with the deficiency, guiding treatment decisions, and preventing complications associated with hemolysis.
