The present invention is directed to a simple process for the modification of the specificity of a peptidase of the hemostatic system by coupling polymers to the peptidase causing it to lose its reactivity in the hemostatic system, but enabling it to continue to react with certain inhibitors, effectors and substrates. The invention is furthermore directed to processes for the detection or quantitative determination of inhibitors of the peptidase in bodily fluids or other samples as well as to processes for their neutralization and/or removal from liquids. Finally, the invention allows the use of a polymer-coupled peptidase as drug and furthermore provides a device which makes use of such a peptidase in the removal of peptidase inhibitors from samples or from the bloodstream of a patient.

The invention relates to a method for determining the total clotting activity of a blood or plasma sample, characterized in that a highly specific, reversible thrombin inhibitor is added to a blood or plasma sample in a defined amount, the clotting of the blood or plasma sample is induced and, after a defined period of time, the consumed amount of the added thrombin inhibitor is determined in a per se known manner, as well as to a kit for obtaining information about the state of coagulation of a blood sample.
