Final answer:
A patient with blood type AB+ is considered the universal recipient because they can receive any blood type without producing anti-A or anti-B antibodies.
Step-by-step explanation:
A patient with blood type AB+ is known as the universal recipient. This patient can theoretically receive any type of blood, because the patient's own blood-having both A and B antigens on the erythrocyte surface-does not produce anti-A or anti-B antibodies. In addition, an Rh* patient can receive both Rh* and Rh blood. However, keep in mind that the donor's blood will contain circulating antibodies, again with possible negative implications.
