Hi Everyone We have an AB neg patient that is platelet dependant Our blood centre cannot supply us with AB neg plts so our patient has been receiving A neg pools instead. If this patient requires a blood transfusion and there is no AB neg rcc's available, which blood group would be the 2nd choice to transfusion i.e A neg or B neg rcc's. Does the decision depend on the number and blood group of the platelets previously transfused to this patient in the last week? thanks
