目的探讨血清降钙素原(PCT)及C反应蛋白(CRP)在检测细菌感染中的价值和应用。方法随机选取142例细菌感染者及64例非细菌感染者作为研究对象,测定两组患者血中PCT和CRP的水平,分析两者用于细菌感染的价值。结果细菌感染者血清PCT与CRP水平均明显高于非细菌感染者,差异均有统计学意义(P<0.01),但PCT敏感性及特异性均优于CRP。结论血清PCT与CRP的检测对细菌性感染性疾病的早期诊断具有重要的应用价值,作为较为理想的早期检测感染性疾病的标志物,PCT检测更具有特异性。
Objective To investigate the value and application of serum procalcitonin (PCT) and C-reactive protein (CRP) in the detection of bacterial infection. Methods 142 cases of bacterial infection and 64 cases of non-bacterial infection were randomly selected as the research object. The levels of PCT and CRP in the two groups of patients were measured, and the value of the two in bacterial infection was analyzed. Results The levels of serum PCT and CRP in patients with bacterial infection were significantly higher than those in non - bacteria patients (P <0.01). However, the sensitivity and specificity of PCT were better than that of CRP. Conclusion The detection of serum PCT and CRP is of great value in the early diagnosis of bacterial infectious diseases. PCT detection is more specific as an ideal marker of early detection of infectious diseases.
