We are starting to implement a Massive Transfusion Protocol and were are trying to find a way to accept platelets back into inventory after being outside the Blood Bank for a few hours. They would be in a cooler, but AABB says that we need to be able to validate that the units were not exposed to cooler temperatures. As of right now we do not accept platelets back into inventory at any time, and we all know that there are not cheap. What is everyone else doing and or using to help validate the function of the platelets? Thanks Bri
