摘　　要：目的探究血常规与超敏C反应蛋白(hs-CRP)检验对肺炎支原体(MP)感染患儿的诊断作用。方法以2020年10月-2023年10月宜丰县人民医院收治的70例MP患儿为研究对象,设为MP组,依据其症状严重程度分为轻症组46例与重症组24例,另选取同期体检健康儿童50名,设为健康组,开展血常规[白细胞计数(WBC)]与hs-CRP检验,比较MP组与健康组、轻症组与重症组的WBC、hs-CRP水平,分析WBC、hs-CRP单独及联合检测对MP感染的诊断效能。结果与健康组患儿比较,MP组患儿WBC、hs-CRP水平更高(P<0.05);与轻症组MP患儿比较,重症组患儿WBC、hs-CRP水平更高(P<0.05);WBC与hs-CRP联合检测对MP感染的诊断准确性、敏感度、特异度高于WBC与hs-CRP单一检测(P<0.05)。结论血常规WBC参数与hs-CRP指标在小儿MP感染筛查中具有一定检验价值,二者联合检验诊断效能更佳。Objective To explore the diagnostic effect of blood routine and high-sensitivity C-reactive protein(hs-CRP)test on children with mycoplasma pneumoniae(MP)infection.Methods A total of 70 children with MP admitted to Yifeng County People's Hospital from October 2020 to October 2023 were selected as the research objects,and were set as MP group.According to the severity of symptoms,they were divided into mild group(46 children)and severe group(24 children).In addition,50 healthy children who underwent physical examination during the same period were selected as the healthy group.Blood routine[white blood cell count(WBC)]and hs-CRP test were carried out.The levels of WBC and hs-CRP in MP group and healthy group,mild group and severe group were compared,and the diagnostic efficacy of WBC and hs-CRP alone and combined detection for MP infection was analyzed.Results Compared with the healthy group,the levels of WBC and hs-CRP in the MP group were higher(P<0.05).Compared with the mild group,the levels of WBC and hs-CRP in the severe group were higher(P<0.05).The diagnostic accuracy,sensitivity and specificity of combined detection of WBC and hs-CRP for MP infection were higher than those of single detection of WBC and hs-CRP(P<0.05).Conclusion The blood routine WBC parameters and hs-CRP indicators have certain test value in the screening of MP infection in children,and the combined test has better diagnostic efficacy.
