Abstract

The present invention provides an analysis element for the determination of coagulation parameters with the help of a detectable or a detection reaction-initiating substrate of a protease of the blood coagulation system and at least one factor and/or co-factor of the blood coagulation system and a buffer substance, wherein the factor and/or co-factor, together with a water-soluble, non-ionic polymer which does not falsely influence the course of the coagulation cascade, is impregnated on an open, planar composite structure which consists of a material which does not have a disturbing influence on the course of the coagulation.
