Our hospital is once again facing a shortage of transfusion preparations. We ask all donors to come to the Faculty Transfusion Department of VFN to donate as soon as possible. Of course, if your current state of health and time schedule allows it. We are currently struggling with a shortage of transfusion preparations of blood groups 0 and A, Rh (D) negative and positive, but we welcome donors of all blood groups. Thank you very much for your help!
