Abstract: A method for predicting a high-grade vesicoureteral reflux in a patient includes the steps of measuring the serum concentration of procalcitonin in a biological sample, assigning a procalcitonin value, looking for a dilation of one or two ureters shown on an echographic image of a kidney, assigning an echographic value, and combining the values by two mathematical equations with the definition of a threshold above which the patient is considered at risk for vesicoureteral reflux. A kit including a device for measuring the procalcitonin concentration and device for measuring the cross-section of the ureter is described.

Abstract: The present invention relates to the field of the distinction between bacterial meningitis and viral meningitis. It relates in particular to an in vitro method for detecting the presence of bacterial meningitis, which comprises determining the concentration of procalcitonin present in a test blood sample and of proteins present in a test cerebrospinal fluid sample, and comparing the concentrations thus determined to the concentration of procalcitonin and of proteins present in a reference sample or to a reference value. It also relates to a kit comprising means for detecting procalcitonin and proteins in the cerebrospinal fluid, and to the use thereof for the production of a diagnostic tool for bacterial meningitis.
