Granulocytes are the white cells which attack and break down bacteria and viruses when you are suffering from an infection. Some patients can become dangerously short of neutrophils (a type of granulocyte) either as a result of their illness or because of the treatment they are receiving. When this happens even the slightest infection can rapidly overwhelm the body’s natural defences and in some extreme cases can cause death.
Granulocytes are collected using a machine called a Blood Cell Separator which removes the granulocytes from your blood.
Granulocyte donations are not required very often. The need for these cells is usually urgent and once they have been donated they must be given to the patient within twenty-four hours.
The donor will be screened for blood borne infections and will recieve single shot of subcutaneous inj. GCSF 12 hours before collection.
