Platelets’ removal is a process that also allows the blood donor to provide a particular blood component. Platelets can save lives, but can be kept only for five days. The platelet removal process is identical to that of plasma removal, only it takes even more time. One unit of platelets is collected from 6-8 doses of blood. It is safer for the patient, because it reduces its exposure to multiple donors, just as with plasmapheresis. Patients who benefit most from receiving platelets are the ones suffering from leukemia. Chemotherapy destroys the platelets, therefore, in order to prevent internal bleeding, platelets are been transfused to the patients.
