Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.

57% Answer Correctly

	positive, negative
	negative, positive
	antigen, negative
	positive, antigen

Solution

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.
