目的 :为了解 C-反应蛋白与感染的关系。方法 :采用全自动激光速率比浊技术检测 CRP,并比较 CRP和 ESR、WBC在感染中的变化。结果 :本组对 80例感染病人进行观察治疗 ,从而证明 CRP对感染的敏感度均优于 WBC和 ESP。结论 :CRP是人血清中非抗体性蛋白质 ,是由肝细胞合成。由于其对炎症反应的敏感度高 ,故在外科工作中检查可及早发现感染并指导用药 ,从而防止滥用抗生素及引起细菌变异和耐药性产生 Objective: To understand the relationship between C-reactive protein and infection. Methods: The CRP was detected by automatic laser turbidimetry, and the changes of CRP, ESR and WBC were compared. Results: This group of 80 patients infected with the observation and treatment, thus proving the sensitivity of CRP infection were better than WBC and ESP. Conclusion: CRP is a non-antibody protein in human serum synthesized by hepatocytes. Due to its high sensitivity to inflammatory reactions, it is possible to detect infections early in surgical work and to guide medication, thus preventing the abuse of antibiotics and causing bacterial variation and drug resistance
