Question

practice it
what type of antibodies are present in plasma for type a blood?
anti-rh antibodies
anti-d antibodies
anti-a antibodies
anti-o antibodies
anti-b antibodies

Explanation:

Blood type A has A antigens on red blood cells. To prevent agglutination (clumping) with incompatible blood types, the plasma contains antibodies against the antigens not present on its own red blood cells. Since type A blood does not have B antigens, it has anti - B antibodies. Anti - Rh (also known as anti - D) antibodies are related to the Rh factor (not directly to the ABO system). Anti - A antibodies would attack the A antigens on type A blood's own cells (which is not the case). There is no such thing as anti - O antibodies as O blood has no A or B antigens.

Answer:

anti - B antibodies
