Abstract：
:Hemostasis, the system of generation and degradation of thrombi, consists of coagulation and fibrinolysis. Whereas global assays to study coagulation have existed for many years, there has been no simple, rapid, and economic routine test for the plasmatic fibrinolysis parameters plasminogen activator inhibitor-1, alpha2-antiplasmin, plasminogen, and aprotinin. Here a fast functional global assay for these plasmatic fibrinolytic parameters is presented. However, the present assay is not sensitive to physiological concentrations of prourokinase or tissue-type plasminogen activator. The following assay conditions have been found to be optimal: 50 microL of citrated plasma is incubated with 50 microL of 10 IU urinary-type plasminogen activator (urokinase)/mL, 1.1 mmol/L tranexamic acid, 1% polygelin, 0.1% Triton X-100, phosphate-buffered saline, pH 7.4, for 20 min at 37 degrees C (plasmin generation phase). Then 50 microL of 3 mmol/L HD-Nva-CHA-Lys-pNA, 1.05 mol/L KCl is added, and deltaA (405 nm)/10 min (37 degrees C) is determined, by using a microtiterplate reader (plasmin detection phase). The results are calibrated against pooled normal plasma (100% plasmatic fibrinolytic parameters activity). The intra- and interassay coefficients of variation have been found to be less than 5%. The detection limit (sensitivity) of the functional fibrinolysis assay is 5 % of the normal plasmatic fibrinolysis parameters activity. The normal plasmatic fibrinolysis parameters activity is 100%, sigma = 25%. The plasmatic fibrinolysis parameters activity correlates negatively (r = -0.684) with the plasminogen activator inhibitor-1 activity of patient samples. The plasmatic fibrinolysis parameters assay is a simple, rapid, and economic functional test for several clinical relevant fibrinolysis parameters.
