4 results about "Blood coagulation test" patented technology

A coagulation test device for measuring clot time and clot characteristics of whole blood samples under different hemostatic conditions. The test results are used as an aid in the management of patients with unexplained coagulopathy for the purpose of helping the physician to determine appropriate clinical measures to hemostasis in the patient.

A device for performing coagulation tests that measure clotting time and clot characteristics in a whole blood sample under different hemostatic conditions. The test results are used to aid in the management of patients with coagulopathy of unknown etiology, helping the physician determine the appropriate clinical action to stop bleeding.

Production was attempted for antibodies that neutralize the activity of a bispecific antibody having F.VIII function-substituting activity, for use in a method for measuring the reactivity of F.VIII in the presence of a bispecific antibody having F.VIII function-substituting activity. As a result, it was discovered that by using the produced antibodies, F.VIII activity in the plasma of a hemophilia A patient can be evaluated accurately by performing APTT-based one-stage clotting assay on a wide range of bispecific antibodies having F.VIII function-substituting activity. It was also discovered that F.VIII inhibitor titer in the plasma of a hemophilia A patient carrying F.VIII inhibitor can be evaluated accurately by APTT-based Bethesda assay.

The invention relates to a test kit used in performing the blood coagulation test known as INR measurement, which enables the user to perform the said test in a practical way at home.
