G6PD Test Test
This test measures the amount of G6PD in your blood to check for an inherited deficiency that can cause red blood cells to break down too quickly.
What this test measures
This test measures the amount of G6PD (glucose-6-phosphate dehydrogenase) in your blood. G6PD is an enzyme that helps red blood cells work properly.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Lower-than-normal results
Lower than normal amounts of G6PD mean you have a G6PD deficiency. Symptoms and risk of hemolytic anemia vary based on personal health history and exposure to triggers. Women with slightly low levels may be carriers without symptoms.
Frequently asked questions
What does G6PD stand for?
G6PD stands for glucose-6-phosphate dehydrogenase.
Who is more likely to have G6PD deficiency?
It mainly affects men and is more common in people of African, Mediterranean, or Asian descent.
What can trigger symptoms in people with G6PD deficiency?
Triggers include fava beans, viral or bacterial infections, certain antibiotics, anti-malaria medicines, and NSAIDs like ibuprofen and aspirin.
Can women have G6PD deficiency?
Women can be affected but are more likely to be carriers without symptoms. They can still pass the gene to their children.
What is hemolytic anemia?
Hemolytic anemia is when red blood cells are destroyed faster than the body can replace them, preventing cells from getting enough oxygen.
