摘　　要：目的讨论降钙素原、C反应蛋白与白细胞计数在老年社区获得性肺炎疾病中的诊断价值。方法选取55例获得性肺炎的老年患者和61例健康人群,分别作为观察组和对照组;均抽取静脉血行各指标检查,均行血液细菌培养和痰液细菌培养,就降钙素原、WBC及C-反应蛋白体内的含量、阳性率和诊断情况进行分析比较。结果观察组各指标的平均含量明显高于对照组(P<0.05);降钙素原检测的准确性、特异性和敏感性均为最高;就细菌阳性检出率看,两组患者之间差异无统计学意义(P>0.05)。结论降钙素原在老年获得性肺炎的诊断中效果显著,WBC和C反应蛋白也有良好的诊断价值,将三种检查联合起来能够大幅度提高诊断的正确性。Objective To investigate the diagnostic value of procalcitonin, C reactive protein and white blood cell count in elderly community acquired pneumonia. Methods 55 elderly patients with acquired pneumonia and 61 cases of healthy people were selected as the observation group and the control group. Venous blood samples were taken for examination of each index. Blood culture and sputum culture were carried out. The content of procalcitonin, WBC and C- reactive protein in vivo, positive rate and diagnosis were analyzed and compared. Results The average content of the indexes in the observation group was higher than that in the control group （P 〈 0.05）; The accuracy, specificity and sensitivity of procalcitonin detection were highest; There was no significant difference between the two groups （P 〉 0.05） on the positive rate of bacterial detection. Conclusion Procalcitonin is effective in the diagnosis of elderly acquired pneumonia, and WBC and C reactive proteins also have good diagnostic value. The combination of three examinations can greatly improve the accuracy of diagnosis.
