PLAT and serum lipopolysaccharide activity: Functional hemostatic assays in whole-blood (impedance aggregometry (Multiplate), Thrombelastography (TEG), Functional fibrinogen) and plasma (TEG with or without addition of tPA to induce fibrinolysis) in nine healthy volunteers before, during and after induction of experimental endotoxemia by means of a 4 h LPS-infusion (0.5 ng/kg/hour).
