Blood Typing

Blood Typing
Blood types are determined by the - answersantigens that are present on the surface of red blood cells (RBCS,
also known as erythrocytes).


Red blood cell membranes contain - answersglycoproteins and glycolipids that determine your ABO blood type
and proteins that determine your Rh (+/-) blood type.


• ABO blood type is determined - answersby the presence of A, B, both (AB), or neither (0) of the A or B
antigens.


• Rh blood type is determined by - answersthe presence of (+) or lack of (-) the D antigen.


The blood plasma may also contain - answersantibodies, depending on the ABO and Rh blood types.


• If you have blood type A, you will have - answersanti-B antibodies.


• If you have blood type B, you will have - answersanti-A antibodies.


If you have blood type 0, you will have - answersboth anti-A antibodies and anti-B antibodies.


• If you have blood type AB, you will NOT have - answersany anti-A nor anti-B antibodies.


• No one has anti-D (Rh) antibodies unless they are - answersRh- AND have been previously exposed to Rh+
blood.


Blood can only be donated from a person with a specific - answersABO antigen to a person without antibodies
for that antigen.


Type A cannot donate to - answersType B or Type O because they both have anti-A antibodies.
