In NC it can be done, BUT it requires preplanning and your doctor must send a request to the Red Cross designating that the patient will be doing dedicated donations.
The donors must go to the main Red Cross location and be sure to tell them that this blood is for patient X.
This was an emergency admission. I live in Massachusetts, and they were vehement about it being impossible, which wouldn’t surprise me. I was at the hospital twelve and a half hours a day, and at least once an hour someone would come in and ominously announce my husband’s hematocrit numbers to me. I refused to allow them to transfuse him. This was in the early 90’s.
