High G6PD (glucose-6-phosphate dehydrogenase): what it means
A G6PD (glucose-6-phosphate dehydrogenase) result above the normal range is considered high. Here is what a raised G6PD (glucose-6-phosphate dehydrogenase) can point to, and when it is worth discussing with a doctor.
Reference range: ~6–20 U/g Hb; an enzyme that protects red cells — a low level (deficiency) causes red-cell breakdown when triggered by certain foods, drugs or infections
Understand your full resultWhat a high G6PD (glucose-6-phosphate dehydrogenase) can mean
- Not typically a clinical concern — a normal or high enzyme level is reassuring; the important direction is a low (deficient) level.
- After a recent haemolytic episode — new young red cells can raise the reading, sometimes masking deficiency (hence testing later).
When to discuss with a doctor
Knowing about G6PD deficiency matters mainly for prevention: someone with it should avoid fava beans and be cautious with specific medicines that can trigger haemolysis, and doctors and pharmacists check drug choices against it. It is worth testing in someone who has had unexplained haemolysis (sudden anaemia with jaundice and dark urine, especially after fava beans, a new medicine or an infection), in a newborn with severe jaundice, and for family screening. Testing is best done when well, a few weeks after any episode, to avoid a falsely normal result. If a trigger causes haemolysis, avoiding it and supportive care usually allow recovery. Mediora.AI shows G6PD alongside the haemolysis markers (haptoglobin, LDH, reticulocytes, bilirubin) so the pattern is read together; the interpretation belongs with your doctor.
