Case 2: A 52-year-old female high school band teacher nearlyfainted one afternoon while demonstrating some trombone-playingtechniques to one of her students. She went to her physiciancomplaining of shortness of breath, mild depression, irritability,and a loss of appetite (which was uncharacteristic). Her physiciannoted signs of anemia and had some hematology tests done. Mostnotable was her hemoglobin of 5.2 g/dL, hematocrit of 14.8%, andreticulocyte count of 10.5%. He sent blood samples to the hospitalblood bank for type and crossmatch for 4 units of red blood cellsfor outpatient transfusion ASAP. The patient was not thrilled atthe prospect of a transfusion since she’d had a bad experience onetime previously when transfused for multiple fractures incurred ina motorcycle accident in her wilder days.
The blood bank tested her samples and got the followingresults:
