Test system for the determination of proteases, active in-vivo in haemostasis, in biological fluids

摘要

Determining in vivo active proteases (I) of hemostasis or trypsin and subtilisin in a biological fluid, comprising incubating the test sample with at least one chromogenic or fluorogenic substrate (A) for the appropriate enzyme, and optional additives, is new. Independent claims are also included for the following: (1) determining the contact phase capacity (CPC) of a biological fluid by treatment with at least one substrate (A') for at least one hemostasis enzyme, at least one contact phase activator (B) and optionally other additives; and (2) test system for the new processes comprising (A) and optionally other additives and auxiliaries.
