Platelets duration and risk
Transfused platelets usuallly only last 2-3 days (I think I may have gone 5-6 days at best when I was platelet transfusion dependent) and must be used within 5 days of being drawn (RBC's can be stored for 42 days). According to an AAMDS article I found, "the immune system can eventually learn to recognize and destroy transfused platelets."
