   Results¹: Patient's post-transfusion plasma     Results²: Patient's post-transfusion red cell eluate

NOTE: These tests were done using blood specimens drawn after the patient had been transfused with 2 units of O Rh negative RBC. The patient's plasma was also retested with the 6 RBC that tested positive before but they were now all negative by gel IAT.

Q #7. What can account for the patient's post-transfusion plasma giving negative panel results?

Q #8. Is an antibody identifiable using the patient's red cell eluate?

Q #9. If the physician had decided to continue transfusing the patient at this stage, what would you advise regarding the compatibility of such transfusions, all of which appear to be compatible in the crossmatch?
