Blood Types
Type O-
A blood type that is universal donor because it does not have any antigens on red blood cells.
Type AB+
A blood type that is universal recipient because it does not have any antibodies in blood plasma.
blood type A
Can donate to AB and A Can receive from O and A
blood type AB+
Can donate to AB+ only Can receive from any positive or negative blood type
blood type B
Can donate to B, AB Can receive blood from O and B
blood type O-
Can donate to EVERY SINGLE BLOOD TYPE Can receive from O- only
Rh antibodies
Form only when Rh- person is sensitized (exposed to Rh factor of Rh+ blood)
ii
Genotype for blood type O
BB
Genotype for homozygous blood type B
Ai
Genotype of heterozygous blood type A
blood type AB
Has A and B antigens Has no antibodies
blood type A+
Has A and Rh antigens Has Anti-B
blood type A
Has A antigens Has Anti-B antibodies
blood type AB+
Has A, B, and Rh antigens Has no antibodies
blood type B
Has B antigens Has Anti-A antibodies
blood type O
Has NO ANTIGENS Has Anti- B and Anti- A antibodies
blood type O
Has no antigens Has Anti- A and Anti-B antibodies
A and B

Antibody
a protein found in the plasma that attack corresponding antigens; not present at birth, but develop a few months after birth
Rh antigen
a protein present on red blood cells of a person with the Rh+ blood
Antigen
a surface marker (carbohydrate or protein) found on the surface of the red blood cells (erythrocytes); present at birth
anti-Rh antibody
develops only when a person is sensitized (exposed) to Rh+ blood
Agglutination
the clumping together of antigens on red blood cells by the action of a corresponding antibodies
