Abstract

The present invention provides a process for the photometric determination of protein C and/or protein S activity, especially in plasma, wherein the sample containing the protein C and/or protein S to be determined is incubated with a protein C activator from snake venom with the formation of activated protein C and/or protein S and the decrease of the formation of thrombin from prothrombin brought about by the coagulation factors and the activators thereof is determined by means of a chromogenic thrombin substrate.
