How it works
Universal recipients have type AB, Rh-positive blood (AB+). Their bodies recognize A, B, and Rh antigens as their own, allowing them to receive red blood cells of any ABO or Rh type
When blood cells are transfused that aren’t compatible with the recipient’s blood type, the immune system recognizes them as foreign invaders and responds by attacking and destroying them (incompatibility). For example, if a person with type A blood received a type B or AB blood transfusion, an ABO incompatibility response would occur. Rh incompatibility can occur when a pregnant woman has Rh-negative blood, and her baby has Rh-positive blood. In addition, a person who is Rh-positive can receive blood from someone who is Rh-negative, but those with a negative blood type cannot receive blood from those with a positive blood type.
Yes, there are many variations of blood types, but these are the 8 most common:
There are more than 600 blood markers outside the ABO blood system. They have been used to identify over 30 rare blood types. These types of blood can be found in 1 out of every 1,000 people (or fewer). Some of these rare blood groups include the1:
- Duffy blood group
- Kell blood group
- Kidd blood group
- Lutheran blood group
But there's one blood type that stands out from the rest—the Rh-null blood type. With fewer than 50 people known to have this blood type, it's truly rare and sometimes referred to as “golden blood.”
