Blood Typing Flashcards
ABO System
Major system of blood typing
Blood Typing
Blood of one person is different from another’s due to presence of antigens on surface of erythrocytes; major method of typing blood is ABO system and includes types A, B, O, and AB; other major method of typing blood is Rh factor, consisting of two types, Rh+ and Rh-
Rh Factor
Antigen marker found on erythrocytes of persons with Rh+ blood
Rh-Negative (Rh-)
Person with Rh- blood type; person’s RBCs do not have Rh marker and will make antibodies against Rh+ blood
Rh-Positive (Rh+)
Person with Rh+ blood type; person’s RBCs have Rh marker
Type A Blood
One of ABO blood types; person with type A markers on his or her RBCs; type A blood will make anti-B antibodies
Type AB Blood
One of ABO blood types; person with both type A and type B markers on his or her RBCs; since it has both markers, it will not make antibodies against either A or B blood
Type B Blood
One of ABO blood types; person with type B markers on his or her RBCs; type B blood will make anti-A antibodies
Type O Blood
One of ABO blood types; person with no markers on his or her RBCs; type O blood will not react with anti-A or anti-B antibodies; therefore, is considered universal donor
Universal Donor
Type O blood is considered universal donor; since it has no markers on RBC surface, it will not trigger reaction with anti-A or anti-B antibodies
Universal Recipient
Person with type AB blood has no antibodies against other blood types and therefore, in emergency, can receive any type of blood
