What is it used for? of Blood donation

Blood donations are used for a number of purposes:

  • Red blood cells are transfused when an illness leads to anaemia. 
  •  Platelets are needed where bone marrow cannot work properly for example, anti-cancer treatment, or in patients who cannot produce normal platelets to clot the blood. 
  •  White blood cells are important to help patients whose resistance to serious infection is low, such as during cancer treatment.
  • Plasma is used for critically ill patients who have lost a large volume of blood and need a replacement of the full range of proteins contained in plasma.
  • Blood is used in cases of acute blood loss, such as after accidents or during an operation.
