Haemoglobin is the protein in red cells that carries oxygen. A low level means anaemia; it is one of the most-checked single markers.
| Measure | Range |
|---|---|
| Men | 13.5–17.5 g/dL |
| Women | 12.0–15.5 g/dL |
| Children | ≈ 11–16 g/dL (age-dependent) |
Symptoms increase as it falls; levels below about 7–8 g/dL often cause marked tiredness and breathlessness and may need urgent treatment. Any low result should be investigated for the cause.
It depends on the cause — iron-rich foods or supplements for iron deficiency, B12/folate if deficient, and treating any bleeding. Your doctor first finds out why it is low.
