  • TYPES OF DONORS
    • Allogeneic
    • Directed
    • Autologous
    • Apheresis
  • Allogeneic
    • For general population
    • Donating blood to same species but different individual
  • Directed
    • “Tagged amounts” (specific patient; ex. Your family)
    • You will reserved a certain blood unit for another individual
  • Autologous
    • Safest type of donation
    • Self-donation
    • For your own future use
    • Common for scheduled surgery (3 days before the surgery)
    • Rare phenotypes (such as Bombay, Rh-)
    • Preserved via Glycerolization then RBC freezing (preserved up to 10 years) Permanent deferred = × allogeneic but autologous
  • Apheresis
    • Separation of blood components
    • Cough and cold = deferred for 48 hours
