Elevated levels of antithrombin III antigen can be observed during the acute bleeding phase in patients with hemophilia, leukemia, or aplastic anemia. Antithrombin inhibits plasma molecules containing serine residues, which in turn suppress thrombin activity, thereby increasing the risk of bleeding. Therefore, elevated antithrombin III indicates that a person may be experiencing active bleeding or has a coagulation disorder, leading to an increased risk of hemorrhage. It is recommended to promptly visit a hospital for evaluation to determine the underlying cause and initiate appropriate treatment, so as not to miss the optimal window for intervention.
