Time independent viscoelastic analysis parameter for prediction of patient outcome

摘要

In some embodiments, the invention provides an in vitro method for identifying a patient as likely as likely to require a transfusion of at least six units of blood in six hours or less. The method comprise, consists essentially of, or consists of (a) analyzing a sample of blood from a patient with a viscoelastic analysis assay to obtain a coagulation characteristic value that is independent of time of the patient; and (b) comparing the coagulation characteristic value of the patient to a coagulation characteristic value that is independent of time of a control,;wherein the coagulation characteristic value of the patient that is lower than the coagulation characteristic value of the control identifies the patient as likely to require a transfusion of at least six units of blood in six hours or less.
