An object of the present invention is to provide a method for easily evaluating residual fibrinolytic resistance activity by PAI-1 and 2AP in blood plasma. The present invention is a method of evaluating fibrinolytic resistance activity, the method including a pretreatment step of adding an anionic surfactant to some of a blood plasma sample derived from a test animal and incubating the blood plasma for a predetermined time, a first fibrinolytic resistance measurement step of measuring an index value of fibrinolytic resistance activity in treated blood plasma obtained by the pretreatment step, a second fibrinolytic resistance measurement step of measuring an index value of fibrinolytic resistance activity in some of the blood plasma sample derived from the test animal, and an evaluation step of evaluating the fibrinolytic resistance activity by PAI-1 and 2AP in the blood plasma of the test animal, based on the index value measured in the first fibrinolytic resistance measurement step and the index value of untreated blood plasma measured in the second fibrinolytic resistance measurement step.

The present invention provides systems, devices, and methods for point-of-care and/or distributed testing services. The methods and devices of the invention are directed toward automatic detection of analytes in a bodily fluid. The components of the device can be modified to allow for more flexible and robust use with the disclosed methods for a variety of medical, laboratory, and other applications. The systems, devices, and methods of the present invention can allow for effective use of samples by improved sample preparation and analysis.

The use of factor Xa in the prevention or treatment in a patient, in particular a human being or an animal, of haemorrhagic events induced by taking anticoagulants.

A cell response assay for cancer is provided. In the assay, the levels of a cancer cell type biomarker, a chemo resistance biomarker and a metastatic potential biomarker are simultaneously measured in a biological sample.

Provided is a method for purifying -thrombin and for quantifying -thrombin and its degradation polypeptides in a liquid proteinatious solution. The method employs a one-step anion exchange chromatography method. The method allows purification and/or quantification of a homogenous post-translationally modified -thrombin. The method can also be used for purification and/or quantification of -thrombin.

A method and kit are provided for monitoring anticoagulant therapy based on measuring the simultaneous influence of factors II and X only, in a test sample (i.e., test plasma or whole blood) of an anticoagulated patient, by creating a corrected sample that circumvents measuring also the influence of fibrinogen, factor V, and factor VII on the clotting process in the corrected sample. One or more coagulation reagents that activate factor VII or factor X, but not factor IX, are added to the corrected sample, and the blood clotting ability of the corrected plasma sample is subsequently determined by measuring blood clotting time. Alternatively, a reagent plasma with added factor VII is mixed into the reagent activator, such as thromboplastin, that is subsequently added to a sample of test plasma or whole blood to correct the test sample and measure the simultaneous influence of only factors II and X.

A method and kit are provided for measuring and monitoring a combined effect of an anticoagulant drug on coagulation factors II and X in a patient taking the anticoagulant drug. The method includes adding one or more coagulation reagents with the factor VII to a test sample and determining blood clotability of the test sample by measuring an influence of factors II and X.
