People with type AB+ blood are universal recipients because they have no antibodies to A, B or Rh in their blood and can receive red blood cells from a donor of any blood type. Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient's red blood cells.
This type is relatively rare (second only to AB). It contains the B antigen on its red blood cells, and the A antibody (to attack A antigens) in its plasma
It just the exact opposite on the southern temperate zone to the northern. Late spring would be late fall. Northern is going into summer as Southern is going into winter.
