C Type is a classification of blood types based on the presence or absence of specific antigens on the surface of red blood cells. It is part of the broader ABO blood group system, which includes types A, B, AB, and O. The C Type specifically refers to the presence of the C antigen, which can affect blood transfusions and organ transplants. Individuals with C Type blood may have different compatibility with other blood types during medical procedures. Understanding C Type is essential for ensuring safe blood transfusions and managing conditions like hemolytic disease of the newborn, where blood type incompatibility can lead to serious health issues.
