目的探讨降钙素原在肺部结核杆菌感染和非特异性细菌感染鉴别诊断中的应用价值。方法选择肺结核(结核组)患者45例和非特异性细菌性肺炎(细菌组)患者45例。两组患者在应用药物前先留取血标本作降钙素原检测。结果细菌组的降钙素原水平(0.396±0.072)ng/ml显著高于结核组(0.195±0.043)ng/ml,差异有统计学意义(P<0.05)。结论降钙素原检测可用来鉴别诊断肺部结核杆菌感染和非特异性细菌感染。
Objective To investigate the value of procalcitonin in the differential diagnosis of pulmonary tuberculosis and nonspecific bacterial infections. Methods Forty-five patients with tuberculosis (tuberculosis) and 45 patients with non-specific bacterial pneumonia (bacteria) were selected. Two groups of patients in the application of drugs before taking blood samples for procalcitonin detection. Results The level of procalcitonin in bacterial group (0.396 ± 0.072) ng / ml was significantly higher than that in tuberculosis group (0.195 ± 0.043) ng / ml, with statistical significance (P <0.05). Conclusion The procalcitonin test can be used to differentially diagnose Mycobacterium tuberculosis and nonspecific bacterial infections in lung.
