|
Term
| If a person has an A gene then which antigen is on their red blood cells? |
|
Definition

| Characteristics of the ABO antibodies |
|
Definition
| naturally occurring, anti-b (A blood), anti-a (B blood), both (O blood) or neither (AB blood), Attack foreign antigens on the RBC surfaces |
|
|
Term
| Distinction and practical importance between A1 and weaker subgroups of A. |
|
Definition
| A1 gene allows for more A antigens to be expressed on the RBC surface, A2 genes do not code for as many enzymes so not as many antigens are A |

| What is Landsteiner's Rule? |
|
Definition
reciprocal antibodies are consistently and predictably present in the sera of normal people whose rbcs lack the corresponding antigen
If you have the antibody you CANNOT have the antigen |
