Blood cannot be directly collected from direct relatives for transfusion In movies and TV shows, there are often scenes where children are injured and parents rush to donate blood. In fact, this is unrealistic. In fact, blood transfusion from relatives, especially close relatives, can easily cause the recipient to suffer from transfusion-related graft-versus-host disease. Therefore, strangers' blood is safer than relatives to a certain extent.
