Our G6PD test measures the levels of glucose-6-phosphate dehydrogenase. This is an enzyme, which is a type of protein that is essential for cellular function.
G6PD helps red blood cells (RBCs) function how they should. It also shields them from potentially harmful byproducts that can accumulate when your body is fighting infection or as the result of certain medications. A lack of G6PD may make RBCs more susceptible to breaking down; this is called hemolysis.
A G6PD deficiency is an inherited disorder. It’s mainly seen in men of African, Asian, or Mediterranean descent. It’s the result of X-linked recessive transmission, which means it’s much more likely to affect men as opposed to women. The G6PD test is often used to determine the causes of hemolytic anemia.
