Duff, Kelly and Kidd are the most clinically significant after AB0 and Rh. They are not generally reported in blood typing blood tests, instead a "screening" is performed. Here a general test of the presence of the most common antibodies in the patient's blood is done (so not the antigens on the blood cells).

In addition, you can do a "cross match" where donor blood is exposed to patient plasma to check for incompatibility
