Abstract Objective： To analysis the clinical value of serum procalcitonin in critically ill patients’ infection diagnosis. Method：150 cases of critically ill patients were chose from July 2011 to July 2014 in our hospital， according to the results of microbiological culture of blood the patients were divided into infected group and non-infected group，patients’ serum procalcitonin and C-reactive protein at the same time were detected， the two indicators of infection in critically ill patients with early diagnostic specificity and sensitivity were compared.Result： The CRP and PCT levels of patients in infected group were significantly higher than non-infected group， the difference was statistically significant（P<0.01）； CRP testing in the diagnosis of patients with severe infection， the specificity was 20.37%（ 11/54）and the sensitivity was 64.58%（62/96）；PCT in the diagnosis of patients with severe infection， the specificity was 46.29%（25/54），and sensitivity was 84.37%（81/96）； PCT detection and early diagnosis in critically ill patients of the specificity and sensitivity were higher than CRP testing， the difference was statistically significant（P<0.05）. Conclusion：Serum PCT and CRP levels in critically ill patients all infected increased， serum PCT detect infection in critically ill patients with a diagnosis of sensitivity and specificity is significantly higher than CRP testing， it can be used for early diagnosis of infection in critically ill patients and treatment.
