摘要
目的评价血清降钙素原(PCT)和C反应蛋白(CRP)在早期诊断细菌感染性疾病中的价值。方法分别测定51例细菌感染患者(细菌感染组)和43例非细菌感染患者(非细菌感染组)血清PCT和CRP水平,并对检测结果进行分析。结果与非细菌感染组比较,细菌感染组患者PCT、CRP水平均显著升高(P<0.05)。PCT及CRP对诊断细菌感染性疾病的灵敏度和特异度分别为98.1%、100.0%和94.1%、76.7%。PCT对诊断细菌感染性疾病的灵敏度和特异度明显优于CRP(P<0.05)。结论 PCT和CRP均可用于诊断细菌感染性疾病,但PCT灵敏度和特异度明显优于CRP。
Objective To evaluate the clinical value of serum level of procalcitonin（ PCT） and C reactive protein（ CRP） in diagnosis of bacterial infection. Methods Serum PCT and CRP levels of 51 patients with bacterial infection（ bacterial infection group） and 43 patients without bacterial infection（ virus infection,non bacterial infection group） were measured respectively,then the results were compared and analysed. Results The PCT and CRP levels of bacterial infection group were higher than those of non bacterial infection group（ P〈0. 05）. On the basis of clinical diagnosis,the sensitivity and specificity of PCT and CRP in diagnosis of bacterial infection were 98. 1%,100. 0% and 94. 1%,76. 7%,respectively. The sensitivity and specificity of PCT was better than CRP（ P〈0. 05）. Conclusion PCT and CRP can be used in the diagnosis of bacterial infectious diseases,but the sensitivity and specificity of PCT is better than CRP.
