Abstract

A test element for the determination of coagulation in a plasma or whole blood sample having a first surface (2a) and a second surface (4a) in a predetermined distance opposite from each other, said both surfaces being provided with two substantially equivalent patterns forming areas of high and low surface energy which are aligned mostly congruent, whereby the areas of high surface energy create a sample distribution system (6) with at least one detection area (6a), wherein the detection area(s) (6a, 6'a) of the first and second surfaces (2a, 4a) is/are provided with at least one coagulation stimulation reagent. The coagulation test element is provided with an integrated quality control system suitable for dry reagent test strip format with a very small sample volume of about 0.5 .mu.L. The production of the inventive coagulation test element involves only a small number of uncomplicated production steps enabling an inexpensive production of the element.
