Blood grouping: Blood groups have been a

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. Blood grouping is a systematic classification of blood based on the presence or absence of specific antigens on the surface of red blood cells. This classification is fundamental to modern medicine, particularly in transfusion therapy, where matching compatible blood types between donors and recipients is crucial to prevent potentially life-threatening reactions. The discovery of blood groups revolutionized medical practice by making blood transfusions safer and more predictable. 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. 2.

About two-thirds of the population contains the third antigen on the surface of their red blood cells known as Rh factor or Rh antigen; this decides whether the blood group is positive or negative.
