The patient's post-transfusion plasma was also retested with the six Red Blood Cell units that tested positive initially. Like the antibody panel performed on the post-transfusion plasma, all six units are now negative by gel IAT.
Unfortunately, the panel results with the patient's post-transfusion eluate do not give clear results (only cells #1 and #9 react) and the antibody remains unidentifiable.
Once the clinical staff was alerted to the presence of an unexpected antibody, the transfusion was stopped. However, suppose that the physician had decided to continue transfusing the patient at this stage. Take a moment to think about what you would advise regarding the compatibility of such transfusions, all of which appear to be compatible in the crossmatch.
