Abstract: Described are determination procedures for fibrinogen and/or fibrinogen-derivatives by matrix-independent turbidimetry. In the FIFTA called procedure the fibrinogen activity is preferably determined in an undiluted sample by addition of thrombin and/or albumin, as well as polybrene if appropriate, in PBS and determination of the increase in absorbance at 405 nm. In the FIATA called procedure the fibrinogen-concentration and/or the concentration of fibrinogen-derivatives is preferably determined by addition of vancomycin and determination of the increase in turbidity at 405 nm. It is standardized by usage of plasma standards of known fibrinogen-activity and/or fibrinogen-concentration.

Abstract: The present invention describes a test system for the determination of in-vivo active hemostasis proteases in biological fluids and the use thereof to determine the in-vivo activation of hemostasis or to diagnose pancreatitis. EDTA and/or EGTA is added to the biological sample to prevent artificial activation of the hemostasis proteases. Arginine and/or guanidine can also be added to the biological sample.

Abstract: A modified limulus test procedure is provided to measure the lipopolysaccharide (LPS), lipid A, and/or glucan reactivity in a biological liquid. The test procedure is independent of the anti-limulus factors present in the sample. The procedure involves strong oxidative treatment of the biological liquid sample.

Abstract: Test system for the determination of in-vivo active hemostasis proteases or of trypsin or subtilisin in biological fluids and the usage thereof to determine the in-vivo activation of hemostasis or to diagnose pancreatitis.
