| Unexpected anomaly 3. Do the results of the initial antibody screen support the presence of the identified antibody?No: All 3 screen cells reacted in the initial screen. Upon review, however, only Screen Cells 1 and 3 were Jk(a+); Screen Cell 2 reacted but was Jk(a-).This anomalous result was investigated by a reference laboratory. It was discovered that the patient had anti-Rd, an antibody to the low frequency antigen Radin (Rd). By chance, Screen Cell 2 was Rd-positive. Radin has a frequency of less than 0.5% in several populations tested. The screen cell manufacturer was notified. They would likely confirm that the cell was Rd-positive, make their clients aware of it, and document it in future antigrams. | View Page |
| Summary This case study presents a scenario in which a patient had an unexpected antibody that disappeared after he was transfused with 2 units of unmatched group O Rh negative RBC. The patient developed a positive DAT with MFA but an antibody identification using the post-transfusion red cell eluate was inconclusive, making the antibody unidentifiable. Fortunately, the patient improved and further transfusion was not required. Ultimately, the patient's antibody was identified as anti-Jka, with a second antibody to a low frequency antigen (Radin) also unexpectedly present.The case illustrates the risks involved in using unmatched blood. | View Page |
