    Melanie Oliveira got a reaction from John C. Staley in Plasma transfusions   
    Sounds like a dilutional effect. How big is the patient and how much plasma/platelets did the patient receive during the time frame between blood draws?
    I have seen this with massively transfused patients and with plasma pheresis patients and with patients who have received multiple products over a few days.

    Melanie Oliveira got a reaction from Bet'naSBB in Backtype discrepancy.. is it anti-a1?   
    Sounds like ABO discrepancy due to a cold agglutinin which may or may not have specificity.   I would run 3 M+ cells and 3 M neg cells at IS, RT and 4'C along with an autocontrol.  IF only the M+ cells react at IS or RT, then I would ficin treat the A1 and B cells and repeat the reverse grouping using ficin treated cells.   Just a suggestion.

    Melanie Oliveira got a reaction from San Diego Blood Banker in IS XM Positive-Next Step?   
    You can't use REST adsorbed plasma to XM.  IT removes ABO iso hemoglutinins.  But use your validated computer system if all else fails.   If your computer is validated and will not let you select ABO incompatible units then it can be used for ABO compatibility.
