List of criteria used for the selection of blood donors List of instruments/materials used for the collection of donors blood Definition Plasmapheresis Cytopheresis Autologous donation Heterologous donation Steps in preparation of a donor prior to venisection and collection of blood Pre and post donation care Screening tests done Common anticoagulants Advantages and disadvantages Changes that occur on blood during storage Ethical issues related to donation Concept of mobile blood bank and public relation in donor recruitment program
3
Donation must be accomplished in such a way that the safety of both the donor and the potential recipient is assured

DEFINITIONS Autologous Autologous derived from organisms of the self; same individual; "autologous blood donation" derived from organisms of the self; same individual; "autologous blood donation" Heterologous Heterologous derived from organisms of a different but related species; "a heterologous blood donation” derived from organisms of a different but related species; "a heterologous blood donation”

To harvest specific cellular components such as platelets, granulocytes or red cells.
