The maintenance of normal blood flow through the vessels is the result of the coordinated work of the coagulation and anticoagulation systems of our body. The balance of this system depends on many factors, including endothelial, humoral, platelet ones, however, we still lack knowledge about the effect of antigenic determinants on the state of the hemostatic system. This study is devoted to assessing the effect of the presence and absence of antigens on the AB0 system, presented on erythrocyte and platelet membranes, on hemostatic parameters. The study was conducted in the Clinics of Samara State Medical University and consisted of127 clinically healthy individuals who underwent a general analysis and biochemical blood analysis, 52 people with the most stable indicators of cell composition and metabolic profile were selected for a coagulation test, including determination of the activity of coagulation factors and routine tests. A significant decrease in the activity of the VIII and VII coagulation factors was revealed, as well as an increase in the prothrombin time in patients with 0 (I) blood group compared to the "antigenic" blood groups. The presence of biological variation for indicators of external and internal coagulation paths was noted, depending on the group of blood belonging to the AB0 system. The findings suggest that there is an increased susceptibility to bleeding in patients with 0 (I) blood groups due to the absence of antigenic determinants on the cell membrane, while for "antigenic" blood groups, on the contrary, there is a susceptibility to thrombosis due to increased activity of the components of the coagulation system.
