Abstract
Method for measuring the coagulation time of a blood sample in which a sample-reagent mixture is formed by introducing the sample and at least one reagent into a cuvette. To reduce the operating and material costs, the sample-reagent mixture is so moved in a stationary cuvette that the mixture flows back and forth around an edge projecting into the cuvette, whereby a clot forms on this edge.
