As I have inherited the processes in Bloodbank, our standard of practice includes the same criteria for platelet transfusion as rbc transfusion... we perform a new type & screen every 72 hours. In my opinion, this is over-kill. However, in order to change my procedure, I need documentation. Can anyone point me in the right direction to pinpoint the exact location in the AABB Technical Manual that specifically states the requirements for pre-transfusion testing when the patient is only getting platelets? Also, any input on what everyone else is doing would be ever so helpful. Same thing for FFP... Thanks.
