Abstract: A method for determining prognosis, diagnosis and theronosis of a sepsis infection in a patient is disclosed. The method involves measuring the age, mean arterial pressure, hematocrit, patient temperature, and the concentration of one or more metabolites that are predictive of sepsis severity. The method can involve obtaining a blood sample from said patient and determining the concentration of the metabolite in the patient's blood; and then determining the severity of sepsis infection by analyzing the measured values in a weighted logistic regression equation.

Abstract: The present invention is directed to methods for diagnosis of sepsis and high risk of sepsis death. Such methods are directed to subjects presenting to healthcare facilities with symptoms for sepsis. Clinico-metabolomic classifiers are tested and compared in the methods of the present invention.
