ABO or blood group antigens, like many other antigens in our body, are an important factor in blood transfusions. When donor blood is transfused into a recipient, some blood components, such as antigens, can lead to the development of various complications, from the occurrence of allergic reactions to organ rejection. That is, blood groups indicate a certain characteristic of blood, and take into account the predisposition to conflict of antigen donors.
Let's look at the AB0 antigenic system in more detail. A link was found between the ABO blood antigen system and sepsis: patients with system A and B antigen incompatibility were more likely to die or suffer from serious complications. Most often, sepsis was caused by a combination of these factors. However, to date, many studies have been conducted on the role of ABO system antigens in sepsis,
