The present invention is a method for selecting a patient to be given a drug for treating septicemia the mode of action of which is to interrupt toll-like receptor 4-derived intracellular signaling. The provided method comprises a step for measuring sCD14-ST in a blood sample from a subject, a step for comparing the measured value with a cut-off value, and a step for selecting a patient as the patient to be given the drug for the treatment of septicemia when the measured value of the sample of that patient is positive in comparison to the cut-off value. The present invention makes it possible to provide a drug to be given to a specific patient to treat septicemia, the mode of action of which is to interrupt toll-like receptor 4-derived intracellular signaling, and to appropriately select the patient to be given the drug and the administration timing or dose.
