The full blood count (also called FBC) test is a common blood test that provides important information about the 3 main types of cells in your blood:
- Red blood cells – containing haemoglobin that helps carry oxygen in your blood to other parts of your body.
- White blood cells – there are different types of white blood cells, that each work in a different way to help to fight infection. The cells types are neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
- Platelets – these are blood cells that help your blood clot, eg, after you are injured.
