摘　　要：目的研究末梢血和静脉血在血常规检验中的价值,并分析其检验的灵敏性。方法对2019年2月至2021年1月到我院进行血常规检查的150例疑似病例作为研究对象,所有研究对象分别抽取末梢血和静脉血实施血常规检查。统计两种不同血液采集方式所获取的血液标本在血常规检验当中的差异和灵敏性等。结果最终确诊血常规异常者148例,经末梢血检出133例异常,静脉血检出146例异常,差异有统计学意义(P<0.05);以实际病症为依据,静脉血液检出的静脉血检验出的血红蛋白、红细胞和白细胞检测值明显比末梢血低,而血小板的计数值明显比末梢血高,差异有统计学意义(P<0.05)。而在中间细胞百分比方面差异无统计学意义(P>0.05);两种血液检查方法在阴性预测值、灵敏性、特异性、准确性、约登指数、误诊率、漏诊率等方面的差异有统计学意义(P<0.05)。结论静脉血检验血常规不仅具有较高的灵敏性,而且检验所得的血液指标更符合病情实际,末梢血相对较差,临床推荐以静脉血采集血液标本作为血常规检验的主要采集途径。Objective To study the value of peripheral blood and venous blood in routine blood tests,and to analyze the sensitivity of their tests.Methods A total of 150 suspected cases who came to our hospital for routine blood examination from February 2019 to January 2021 were used as the research objects.All subjects were drawn peripheral blood and venous blood for routine blood examination.To collect statistics on the differences and sensitivity of blood samples obtained by two different blood collection methods in routine blood tests.Results The final diagnosis was 148 cases of abnormal blood routine,133 cases of abnormalities were detected by peripheral blood,and 146 cases of abnormalities were detected by venous blood,the difference was statistically significant(P<0.05).Based on actual symptoms the detection values of hemoglobin,red blood cells and white blood cells in the venous blood test were significantly lower than those in peripheral blood,while the platelet counts were significantly higher than those in peripheral blood,and the difference was statistically significant(P<0.05).However,there is no difference in the percentage of intermediate cells(P>0.05).The two blood test methods have differences in negative predictive value,sensitivity,specificity,accuracy,Youden index,misdiagnosis rate,and missed diagnosis rate(P<0.05).Conclusion The blood routine of venous blood test not only has high sensitivity,but also the blood index obtained by the test is more in line with the actual condition of the disease,and the peripheral blood is relatively poor.It is clinically recommended to collect blood samples from venous blood as the main blood collection method for routine blood tests.
