目的:探讨血清降钙素原(PCT)、白细胞计数及中性粒细胞百分比在诊断细菌性感染疾病中的临床价值。方法:收集2015年1月-2016年1月我院收治的细菌性感染疾病158例,收集同期我院收治的非细菌性感染性疾病患者149例,选择同期于我院体检的150例健康体检者,分别检测三组血清PCT、白细胞计数及中性粒细胞百分比。结果:细菌性感染组PCT、WBC计数和中性粒细胞百分比均高于非细菌性感染组、健康体检组,差异有统计学意义(P<0.05);细菌性感染组PCT阳性率、WBC计数阳性率均高于非细菌性感染组,差异有统计学意义(P<0.05)。结论:血清降钙素原、白细胞计数及中性粒细胞百分比异常升高对细菌性感染的早期诊断具有重要参考价值。
Objective: To investigate the clinical value of serum procalcitonin (PCT), white blood cell count and neutrophil percentage in the diagnosis of bacterial infections. Methods: A total of 158 bacterial infections were collected from January 2015 to January 2016 in our hospital. A total of 149 cases of non-bacterial infectious diseases were collected in our hospital during the same period. 150 cases of physical examination The three groups were detected serum PCT, white blood cell count and neutrophil percentage. Results: The counts of PCT, WBC and the percentage of neutrophils in bacterial infection group were significantly higher than those in non-bacterial infection group and healthy control group (P <0.05). The positive rate of PCT, WBC count The positive rate was higher than non-bacterial infection group, the difference was statistically significant (P <0.05). Conclusion: The abnormality of serum procalcitonin, leukocyte count and the abnormal percentage of neutrophils have important reference value for the early diagnosis of bacterial infection.
