Dr Bart van de Ven needed to do a blood transfusion in his patient so far twice in his life. So the incidence is very low. If it is necessary the blood lab will ALWAYS do a cross test with the blood of the patient before giving the blood so why test it before? In the case of acute need for blood the blood group O-negative is given. This occasion did not ever occur in our practice (but Dr van de Ven’s blood group is O neg which means he would be able to give his own blood…:).
