G6PD (Glucose 6 phosphate dehydrogenase) Blood Test

G6PD is an important enzyme that helps protect red blood cells from damage. A deficiency in G6PD can lead to episodes of red blood cell breakdown (haemolysis), which may cause anaemia, jaundice, and fatigue, particularly after exposure to certain medications, infections, or foods. This test helps diagnose G6PD deficiency, a genetic condition that is more common in certain ethnic groups.
