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.

FAQs
What does G6PD do?
G6PD helps the red blood cells to function normally. G6PD also helps protect red blood cells against substances that can build up when you have a fever or take certain medicines.
What could a low G6PD result mean?
If there is not enough G6PD to protect the red cells, some may be destroyed during fever or while taking these medicines. This is called haemolysis and may be associated with jaundice. If this happens, you may not have enough red blood cells and may become anaemic.
What is G6PD?
G6PD, glucose 6 phosphate dehydrogenase, is a chemical found in red blood cells which carry oxygen to all parts of your body.
