What are red cells?

Red cells look a bit like doughnuts but with an indented centre instead of a hole. 

They give blood its colour and make up 40% of your total blood volume. A protein called haemoglobin makes them red.

What do they do?

Red cells have two main functions: 

  • Carrying oxygen to all parts of your body, and
  • Removing waste products such as carbon dioxide from your body.

Are there options other than a red cell transfusion?

Certain treatments or operations can’t be safely carried out without a red cell transfusion. However, if other care options are available, they should be used.

Who do red cell transfusions help? 

As the image below shows, red cells can help in many ways: from treating cancer and blood diseases to other causes of anaemia, and so much more.
