    摘要： In some embodiments, the invention provides methods for detecting an aberrant fibrinolysis condition in a patient. The method includes subjecting a blood sample from the patient to a viscoelastic analysis in the presence of a known amount of a thrombolytic agent, to obtain a coagulation characteristic value of the patient; and comparing the coagulation characteristic value of the patient to a coagulation characteristic value of a healthy individual, the coagulation characteristic value of the healthy individual obtained by subjecting a blood sample from a healthy individual to the viscoelastic analysis in the presence of the known amount of the thrombolytic agent, wherein a difference in the coagulation characteristic value of the patient as compared to the coagulation characteristic value of the healthy individual identifies the patent as having aberrant fibrinolysis. In some embodiments, the invention also provides a container adapted for detecting an aberrant fibrinolysis condition in a blood sample using viscoelastic analysis comprising an interior having a coating comprising a thrombolytic agent.

    摘要： The invention provides methods for identifying a patient as likely to have an onset of massive hemorrhage. In one embodiment, the invention provides a method for identifying a patient as likely to have an onset of massive hemorrhage, the method comprising measuring at least one of first coagulation characteristic parameter reflective of a clotting time in a sample of blood of the patient, a second coagulation characteristic parameter reflective of clot formation in a sample of blood of the patient using the viscoelastic assay to obtain a second result; a third coagulation characteristic parameter reflective of clot strength in a sample of blood of the patient using the viscoelastic assay to obtain a third result; and a fourth coagulation characteristic parameter reflective of clot lysis in a sample of blood of the patient using the viscoelastic assay to obtain a fourth result; wherein, a positive for at least one of the first result, second result, third result and fourth result identifies the patient as likely to have an onset of massive hemorrhage.

    摘要： In some embodiments, the invention provides methods for detecting fibrinolysis or hyperfibrinolysis in a blood sample from a patient. The method includes subjecting a first portion of a blood sample comprising reduced platelet function to viscoelastic analysis in the absence of an inhibitor of fibrinolysis to obtain a coagulation characteristic of the first portion at a time point; and subjecting a second portion of the blood sample comprising reduced platelet function to viscoelastic analysis in the presence of an inhibitor of fibrinolysis to obtain a coagulation characteristic of the second portion at the time point; wherein a difference between the coagulation characteristic of the first portion and the coagulation characteristic of the second portion indicates fibrinolysis or hyperfibrinolysis in the blood sample.
