GRN and Sepsis: AUC values for progranulin in the combined sample (241 patients with sepsis and 48 patients with localized infection) were 0.90 (95% CI = 0.86–0.94) and 0.89 (95% CI = 0.84–0.94) for procalcitonin (p = 0.790) for the identification of patients with localized infections in the absence of sepsis.
