it seems like it should be new specimen for each/every admission whether it's same hospital or different hospitals within a system. Blood Banks usually re-draw a specimen if patient went home and came back and re-admitted within 3 days. This scenario is totally different from hospital B performing compatibility testing for a transfusion in hospital A who has limited transfusion service testing. I guess as long as your validated system allows it, it can be done if SOP is created, contract drawn signed by your Pathologists and Administrators from each hospital.
