Abstract
A 62-year-old man is admitted with lower gastrointestinal bleeding and symptomatic anemia; his hemoglobin (Hgb) level is 5.0 g/dL. The patient has a known history of a warm autoantibody but no alloantibodies and was transfused two units of red blood cells (RBCs) 1 month ago at the hospital. A type and screen sample (ethylenediaminetetraacetic acid [EDTA] anticoagulant) is submitted to the blood bank.
