The present invention relates to a method for diagnosing anomalies in the coagulation of blood, comprising the following successive steps: a) placing a sample of total blood in a holder containing two pairs of electrodes connected to an apparatus generating an electrical current; b) incubating this sample for 60 to 180 seconds in the presence of calcium; c) adding to this sample tissue factor in a concentration high enough to trigger the coagulation of the blood; d) measuring the impedance variation between the electrodes as a function of time, for a period comprised between 10 and 30 minutes from step (c), and generating a curve of the impedance values as a function of time; e) comparing the value of the area under the curve generated in step (d) with the value of an area under a reference curve.
