The transfusion medicine telemedicine service has enabled the provision of transfusion services in hospitals lacking specialist doctors in the area of transfusion. The Croatian Institute of Emergency Medicine has developed a device and application for exchanging the materials needed to perform various tests (BT, BT+DAT, BT+Rh phenotype, N1, N1+Du, IAT, DAT, IAT+DAT). The telemedicine specialist center that provides transfusion medicine telemedicine services to hospitals in the Republic of Croatia is the Croatian Institute for Transfusion Medicine.
