Abstract
A 70-year-old male with myelodysplastic syndrome presents for an outpatient transfusion. His hemoglobin (Hgb) level is 6.7 g/dL. The patient received two units of RBCs 2 months ago, and the antibody screen was negative at that time. A type and crossmatch sample (ethylenediaminetetraacetic acid, EDTA anticoagulant) is submitted to the blood bank; two units of RBCs are requested for the patient.
