Blood type Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also known as a blood group) is a classification of blood based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). It details the discovery of the ABO system and Rh factor, outlines blood typing, and explains the characteristics of various blood groups, including the universal donor (type O) and universal recipient (type AB). Among the many aspects of blood, knowing your blood group stands out as critically important. Blood grouping refers to the classification of blood based on the presence or absence of specific antigens on red blood cells, primarily categorized into the ABO and Rh systems. Blood groups have been a topic of interest and research for many years. With advances in medical science, the knowledge and understanding of blood groups have also increased. This article will discuss everything you need to know about blood groups, including what they are, how they are determined, their importance, and their impact on medical procedures and transfusions.
