目的探讨下呼吸道感染血清降钙素原测定在诊断中临床意义。方法 009年3月至2011年10月于我院诊治的符合入选标准的下呼吸道感染患者83例,其中细菌感染39例,病毒感染24例,支原体感染20例检测的WBC、PCT、CRP进行观察。结果细菌感染组PCT(1.20±0.04)ng/ml、病毒感染组(0.15±0.05)ng/ml、支原体感染组(0.16±0.06)ng/ml,经比较P<0.05,差异有统计学意义。结论血清降钙素原血清水平对下呼吸道感染中细菌感染的有着显著的指导意义,特异性高、灵敏度良好、便于检测,可以作为临床上对感染进行鉴别诊断重要依据和指标。
Objective To investigate the clinical significance of serum procalcitonin in the diagnosis of lower respiratory tract infection. Methods Eighty-three patients with lower respiratory tract infection were enrolled in our hospital from March 2009 to October 2011. Among them, 39 were bacterial infection, 24 were viral infection, and 20 were detected by WBC, PCT and CRP in mycoplasma infection . Results The difference was statistically significant (P 0. 05) between the bacterial infection group (1.20 ± 0.04) ng / ml, viral infection group (0.15 ± 0.05) ng / ml and mycoplasma infection group (0.16 ± 0.06) ng / Conclusions Serum procalcitonin serum has significant guiding significance for bacterial infection in lower respiratory tract infection. It has high specificity, good sensitivity and is easy to detect. It can be used as an important basis and index for the differential diagnosis of infection in clinic.
