血涂片显微镜检查在血常规检验中的必要性分析

Microscopic Examination of Bblood Smears on the Necessity of Analyzing Blood Tests

目的:探讨和论证血涂片显微镜检查在血常规检验时中的必要性。方法将2013年5月~12月共980份血液标本采用血液分析仪检查,对其中符合检查标准的400份标本进行血涂片显微镜检查,对400份血液标本进行血涂片显微镜检查的结果与采用血液分析仪检查的结果进行对比分析。结果血液分析仪检测结果与血涂片显微镜检查结果259例(64.75%)相符,141例不相符(35.25%)具体体现在:血液分析仪检测结果显示 WBC正常或升高,N升高时,血涂片显微镜检查结果异常率为18.25%(73/400),当WBC正常或升高或降低,B、M计数改变时,血涂片显微镜检查结果异常率为11.5%(46/400),即将 WBC正常或升高或减低, RBC、HB、MCV、RDW等指标异常时,红细胞形态有明显变化,主要表现为红细胞大小不等、高色素性。结论血涂片显微镜检查可提高血液标本检测结果的准确性,可为临床医生提供更可靠的诊断依据,应加以重视。

Objective To investigate and demonstrate the need for microscopic examination of blood smears when the blood of the inspection.Methods February 2013-October 2013 period were 980 blood specimens using blood analyzers to check for compliance with inspection standards which 400 specimens of blood smear microscopy of blood samples from 400 blood smear microscopy check the results with the results of the use of the blood analyzer checks were analyzed.Results Hematology analyzer test results with the results of microscopic examination of blood smears 259 cases(64.75%)match,141 cases do not match(35.25%)embodied in:blood analyzer test results showed normal or elevated WBC,N rises,blood abnormal smear microscopy result was 18.25%(73/400),when the WBC normal or elevated or lowered,B,M count changes,abnormal results of blood smear microscopy was 11.5%(46/400),is about WBC normal or elevated or reduced,while RBC,HB,MCV,RDW and other indicators of abnormal red blood cellmorphology changes significantly,mainly for the red blood cellsize,high pigmented.Conclusion Blood smear microscopy can improve the accuracy of the test results of blood samples,can provide a more reliable basis for clinical diagnosis of doctors,at ention should be paid.
