Good Morning, We have a patient with a Warm Autoantibody transfused the middle of June. The patient is now "being followed" by Oncologist with Direct Coombs testing every couple of weeks or so. Patient has been seen in our facility for the last few years and has only received blood the one time in June. My question: the Direct Coombs is IgG 1+, C3d neg. It has not varied since transfusion. Would you recommend repeating the eluate each time even though patient was transfused greater than 28 days ago? Eluate - all panel cells react at equal strength.
