Our test for G6PD (its full name is Glucose-6-Phosphate Dehydrogenase) measures the amount of this enzyme in your red blood cells. G6PD protects these cells from being damaged by oxidation (also frequently referred to as damage by free radicals, which are groups of atoms containing a free electron & an oxygen atom, which can destroy cells). G6PD deficiency is one of the world’s most common enzyme deficiencies.
When should I get tested?
A deficiency of G6PD is often caused by a mutation in its gene, which is found on the X chromosome of your DNA. It is often recommended in the case of newborn jaundice, when there is no other obvious cause. Your doctor may suggest that you have your G6PD tested if you have had haemolysis, a condition causing jaundice, anaemia, & dark urine; or you may wish to have the test to know whether or not you have the deficiency.
What does the test include
Your G6PD levels are measured using a blood test.
