目的 :探究血清降钙素原在下呼吸道感染疾病中的诊断价值。方法 :将在我院确诊的下呼吸道感染患者作为观察组,将同时期内在我院体检的健康人作为对照组,比较两组研究对象的血清降钙素原、白细胞计数、C反应蛋白水平、灵敏度及特异度。结果:观察组患者的血清降钙素原、白细胞计数及C反应蛋白值均高于对照组,重症患者的血清降钙素原、白细胞计数及C反应蛋白水平均明高于局部感染患者,PCT诊断灵敏度、特异度均高于CRP、WBC检测(P<0.05)。结论 :以血清降钙素为诊断标志物能够提高下呼吸道感染疾病的诊断准确率,反应病情的发展变化过程,有利于为下呼吸道感染疾病的临床治疗提供科学指导,值得推广。
Objective: To investigate the value of serum procalcitonin in the diagnosis of lower respiratory tract infection. Methods: The patients with lower respiratory tract infection diagnosed in our hospital were taken as the observation group. The healthy people in our hospital during the same period were taken as the control group. The serum procalcitonin, white blood cell count, C-reactive protein, Sensitivity and specificity. Results: Serum procalcitonin, white blood cell count and C-reactive protein in the observation group were higher than those in the control group. Serum procalcitonin, white blood cell count and C-reactive protein levels were significantly higher in the patients with severe disease than those with localized infection. PCT The diagnostic sensitivity and specificity were higher than those of CRP and WBC (P <0.05). Conclusion: Serum calcitonin as a diagnostic marker can improve the accuracy of the diagnosis of lower respiratory tract infection, the reaction of the disease progression and development, is conducive to the clinical treatment of lower respiratory tract infection provide scientific guidance, it is worth promoting.
