A 41-year-old woman with Crohn’s disease presents for outpatient transfusion. The patient has a history of symptomatic chronic anemia as per the patient’s gastroenterologist and has received several blood transfusions at another hospital in the past, though none in the past 2 years. An ethylenediaminetetraacetic acid (EDTA) anticoagulant sample is submitted to the blood bank (properly labeled with the patient’s last name, first name, medical record number [MRN], and date of birth [DOB]: “SMITH, JULIE; MRN 1001234; DOB 3/20/####*”; * denotes year 41 years ago from current date) for type and screen along with a request for crossmatch of two red blood cell (RBC) units. There are no prior test (i.e., type and screen) results in your blood bank information system; in fact, this is the first admission to your hospital facility for this patient (i.e., a new patient).
