Used in biomedical research to quantify levels of human coagulation factor XIII in plasma or serum samples. Enables assessment of factor XIII deficiency, which can lead to bleeding disorders. Supports studies on thrombosis, hemostasis, and fibrinolysis. Commonly used in clinical laboratories and research settings to investigate clot stability and evaluate patients with unexplained bleeding or recurrent miscarriages. Also applied in monitoring factor XIII replacement therapy and in the development of new hemostatic drugs.
