Description
G6PD deficiency is a common inherited condition that can trigger red blood cell breakdown in response to certain medications, foods and infections — and a single test tells you whether you carry it.
About the G6PD Deficiency Test
Glucose-6-Phosphate Dehydrogenase (G6PD) is an enzyme that protects red blood cells from damage. When it is deficient, exposure to specific drugs, foods such as fava beans, or infections can cause the cells to break down, leading to anaemia. Screening is especially important in this region, is routinely done for newborns, and is valuable for adults who have never been tested, so that triggering exposures can be avoided.
Preparation and turnaround
A straightforward venous blood sample is taken with no fasting required. The appointment takes just a few minutes and results are typically available within one to two working days. If deficiency is confirmed, your doctor can provide a list of substances to avoid.
Frequently asked questions
Why is G6PD screening important?
Knowing your status lets you avoid medications and foods that could trigger red cell breakdown, preventing episodes of anaemia.
Is G6PD deficiency inherited?
Yes. It is a genetic condition passed down through families and is more common in men. It does not change over time.
Does the test require fasting?
No. No fasting or special preparation is needed for G6PD testing.
