摘　　要：目的探讨降钙素原(PCT)与高敏C-反应蛋白(hs-CRP)对早期肺炎患者的诊断价值。方法将门诊治疗的120例呼吸道感染患者分为肺炎组57例与非肺炎组63例。比较两组患者白细胞(WBC)计数、PCT与hs-CRP水平,以PCT为诊断金标准,计算hs-CRP、WBC计数诊断肺炎的灵敏度、特异度。结果两组患者hs-CRP、WBC计数水平比较,差异无统计学意义(P>0.05);非肺炎组患者PCT水平明显低于肺炎组,差异有统计学意义(P<0.05)。hs-CRP、WBC计数诊断肺炎的灵敏度、特异度分别为(56.3%、68.7%)、(46.2%、59.4%)。结论肺炎急性期发作时,PCT较hs-CRP能更早显示肺部感染征象。Objective To investigate procalcitonin（PCT）and high-sensitivity C reactive protein（hs-CRP）in diagnosis of early pneumonia.Methods Outpatient treatment of 120 cases of respiratory tract infection were divided into group 57 cases and 63 cases of non pneumonia group.Comparison of two groups of patients with white cell count（WBC）, PCT and hs-CRP levels,with PCT as the gold standard in the diagnosis of hs-CRP,WBC count,calculate the sensitivity and specificity of diagnosis of pneumonia.Results Compared two groups of patients with hs-CRP,the count of WBC level,the difference was not statistically significant（P〈0.05）;non pneumonia group PCT levels were significantly lower in pneumonia group,the difference was statistically significant（P〈0.05）.Hs-CRP diagnosis of pneumonia,the count of WBC sensitivity,specificity were respectively（56.3%,68.7%）,（46.2%,59.4%）.Conclusion Pneumonia in acute stage of attack,PCT can earlier signs of pulmonary infection is hs-CRP.
