Study Notes
ABO Blood Group
- ABO blood group consists of four blood types: A, B, AB, and O, determined by the presence or absence of antigens and antibodies.
- Antibodies are proteins in plasma that recognize and alert the immune system to destroy foreign substances like germs.
- Antigens are protein molecules on the surface of red blood cells.
Blood Grouping
- Blood grouping is done using the antigen-antibody reaction method.
- Blood is classified into two main systems: ABO and Rh.
Rh Factor
- The Rh factor determines the presence or absence of antigen D on the surface of red blood cells.
- Individuals with antigen D are Rh positive, while those without it are Rh negative.
Characteristics of Blood Groups
- Group A: has A antigen on red blood cells and Anti-B antibodies in plasma.
- Group B: has B antigen on red blood cells and Anti-A antibodies in plasma.
- Group AB: has A and B antigens on red blood cells and no antibodies in plasma.
- Group O: has no antigens on red blood cells and Anti-A and Anti-B antibodies in plasma.
Learn about the ABO blood group system, including the different blood types and the role of antigens and antibodies in the classification process.
