Glucose-6-phosphate dehydrogenase (G6PD)


Test Background
G6PD is an important factor in red blood cell metabolism. A deficiency of G6PD is the most common human enzyme defect and the defect is the result of mutations on the X chromosome, which makes G6PD an X-linked recessive hereditary disease.


Clinical Indications
G6PD testing is a useful follow-up to enzyme testing to determine or confirm an underlying cause of one or more unexplained episodes of haemolytic anaemia, or presence of persistent jaundice.
