Method for assaying D-dimers that are specific to venous thromboembolism in a patient blood sample, said method comprising on the one hand the assay of D-dimers of the sample in order to obtain the level of D-dimers in the sample (Ddi E), and on the other hand, the dynamic measurement of the fibrin formation in this same sample, said dynamic measurement comprising the following steps: a) initiating the activation of the coagulation in the sample without triggering it; b) incubating the mixture obtained in step a), and triggering, in the incubated sample, the generation of thrombin and the formation of a fibrin clot; c) measuring the temporal variation of at least one property of the sample obtained in b), wherein the fibrin clot is formed; d) establishing the formation profile of the fibrin clot analysed in c), and extracting from this profile the fibrin formation time measured at the inflection point of the tangent of the curve of the profile, the value of the property (Vp) of the sample measured at the reaching time of the polymerisation plateau of the fibrin; e) calculating the level of D-dimers resulting from the degradation of the intravascular fibrin: e1) by adjusting the level of D-dimers of the sample (Ddi E) according to the level of the D-dimers generated by hypercoagulation by using TFF determined in d), in order to obtain the level of adjusted D-dimers according to hypercoagulation (Ddi E/HC), and e2) by adjusting the level of adjusted D-dimers Ddi E/HC obtained in e1) according to the level of the D-dimers generated by inflammation by using Vp determined in d), in order to obtain R; f) comparing the level of D-dimers resulting from degradation of the fibrin R obtained in e), with respect to a threshold, preferably to the threshold of 0.5 μg/mL; g) determining the level of fibrinogen degradation products generated by hyperfibrinolysis (PDFg) present in the coagulation activation by using the level of D-dimers resulting from degradation of the fibrin, R, obtained in e) and the level of D-dimers of the sample (Ddi E). h) comparing the level PDFg obtained in g) with respect to a threshold, and comparing the fibrin formation time obtained in d) with respect to a threshold. a) initiating the activation of the coagulation in the sample without triggering it; b) incubating the mixture obtained in step a), and triggering, in the incubated sample, the generation of thrombin and the formation of a fibrin clot; c) measuring the temporal variation of at least one property of the sample obtained in b), wherein the fibrin clot is formed; d) establishing the formation profile of the fibrin clot analysed in c), and extracting from this profile the fibrin formation time measured at the inflection point of the tangent of the curve of the profile, the value of the property (Vp) of the sample measured at the reaching time of the polymerisation plateau of the fibrin; e) calculating the level of D-dimers resulting from the degradation of the intravascular fibrin: e1) by adjusting the level of D-dimers of the sample (Ddi E) according to the level of the D-dimers generated by hypercoagulation by using TFF determined in d), in order to obtain the level of adjusted D-dimers according to hypercoagulation (Ddi E/HC), and e2) by adjusting the level of adjusted D-dimers Ddi E/HC obtained in e1) according to the level of the D-dimers generated by inflammation by using Vp determined in d), in order to obtain R; e1) by adjusting the level of D-dimers of the sample (Ddi E) according to the level of the D-dimers generated by hypercoagulation by using TFF determined in d), in order to obtain the level of adjusted D-dimers according to hypercoagulation (Ddi E/HC), and e2) by adjusting the level of adjusted D-dimers Ddi E/HC obtained in e1) according to the level of the D-dimers generated by inflammation by using Vp determined in d), in order to obtain R; f) comparing the level of D-dimers resulting from degradation of the fibrin R obtained in e), with respect to a threshold, preferably to the threshold of 0.5 μg/mL; g) determining the level of fibrinogen degradation products generated by hyperfibrinolysis (PDFg) present in the coagulation activation by using the level of D-dimers resulting from degradation of the fibrin, R, obtained in e) and the level of D-dimers of the sample (Ddi E). h) comparing the level PDFg obtained in g) with respect to a threshold, and comparing the fibrin formation time obtained in d) with respect to a threshold.
