Why do you have to wait 16 weeks between blood donations?
There’s an important link between your red cells and your health because it’s these cells, or rather the red-coloured haemoglobin they contain, that take oxygen around your body. Haemoglobin contains iron and some is lost with each blood donation. To compensate, iron is mobilised from the body's iron stores, and the body also increases the amount of iron it absorbs from food and drink. Any iron deficiency can result in reduced haemoglobin levels, and eventually, if not treated, in iron deficiency anaemia. This deficiency can make you feel tired, which is why, as well as asking you to wait 16 weeks to donate whole blood, we also test your haemoglobin levels every time you give. We make sure that your haemoglobin level is above 125g/l for women and135g/l for men.
