Iron and ferritin blood test — Norya

Which blood values?

Ferritin reflects body iron stores; low ferritin supports iron deficiency. Haemoglobin (HGB) may be low in anaemia. MCV (mean cell volume) is often low or normal in iron-deficiency anaemia. No single value makes a diagnosis; your doctor will interpret tests together. Iron supplements should be used on medical advice. You can also compare this pattern with our guides to ferritin and hemoglobin.
