G6PD (Glucose 6 phosphate dehydrogenase) Blood Test

About this test

G6PD, glucose 6 phosphate dehydrogenase, is a chemical found in red blood cells which carry oxygen to all parts of the body.

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.

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 the person may not have enough red blood cells and may become anaemic.

Most people with G6PD deficiency have completely normal health. However, problems can occur occasionally. These problems are much more common in boys and men with G6PD deficiency than girls and women. Some children and adults with G6PD deficiency may develop haemolysis and anaemia if they get a fever or if they take one of the medicines listed below. Some people may develop haemolysis and anaemia if they eat broad beans (this is called favism). An affected person feels unwell, becomes pale and jaundiced (yellow) and may have a backache and pass dark urine.
