ABSTRACT:
The method and the apparatus serve for testing and measuring blood clotting time. Blood or blood plasma (12) and a reagent (13) are introduced into a measuring cuvette (8). The clotting time is measured electrooptically with the aid of a stirring element (9) which is arranged in the measuring cuvette (8), can be attracted magnetically and is driven by a magnetic stirring device arranged outside the measuring cuvette (8). The method and apparatus are suitable for automatic measuring methods owing to the fact that blood plasma (12) and reagent (13) are introduced beside one another onto an essentially horizontal internal surface (10) of a measuring cuvette (8) provided with an opening above this surface (10), in that the measuring cuvette (8) and its contents are heated to the reaction temperature (step 7), in that the measuring cuvette is pivoted by essentially 90.degree. in such a way that the internal surface (10) stands essentially perpendicular and plasma (12) and reagent (13) flow together, and in that the measurement is subsequently carried out.
