G6PD or glucose 6 phosphate dehydrogenase is an enzyme that is responsible for protecting your body cells from chemical and environmental damage, especially against free radicals-induced damages. G6PD deficiency is a genetic disorder that occurs due to malnutrition and a change in the genetic predisposition in your G6PD gene.
This enzyme plays a crucial role in the functioning of your RBCs. In case of a deficiency, your RBCs might not receive adequate amounts of oxygen and start to break down, otherwise referred to as haemolytic anaemia.
G6PD deficiency alone might not cause haemolytic anaemia or other health complications. A G6PD test helps your healthcare provider understand whether you have glucose 6 phosphate dehydrogenase deficiency or not and the associated risks and complications.
Even though you might not be exhibiting any symptoms, you may have G6PD deficiency. So, your healthcare provider may recommend a G6PD deficiency test to gauge your G6PD levels against the normal level.
