血常规检验中常见误差产生的原因及解决策略

Causes of Common Errors in Routine Blood Test and Their Dolutions

目的分析血常规检验中常见误差产生的原因,并提出解决策略。方法选取2018年3~10月在我院进行健康体检的379名受检者,应用全自动血细胞分析仪对其血液标本进行血常规检测,分析误差引起的原因,并提出有针对性的解决策略。结果血常规检验误差总发生率为5.54%,引起原因主要包括未及时送检血液标本(38.10%)、保存不当(28.57%)、采集部位不合理(23.81%)及其他因素(9.52%)。不同的保存温度以及不同的放置时间,白细胞(WBC)计数与血小板(PLT)计数比较差异均有统计学意义(P<0.05)。末梢血红细胞计数(RBC)低于静脉血,PLT及WBC均高于静脉血,差异有统计学意义(P<0.05)。结论在血常规检测中误差的发生率较高,根据血常规检验中常见误差产生的原因采取针对性防控措施可提高检验结果的准确率,有助于为临床病情诊断及治疗提供客观依据。

Objective To analyze the common errors in routine blood tests and their causes, and to propose solutions. Methods Select 379 subjects who underwent physical examinations in our hospital from March 2018 to October 2018, and use the automatic blood cell analyzer to perform routine blood tests on their blood samples, analyze the causes of errors and take targeted measures resolution strategy. Result The total incidence of errors in routine blood tests in this study was 5.54%. The main causes of errors in routine blood tests included failure to send blood samples in time(38.10%), improper storage(28.57%), unreasonable collection sites(23.81%), and other factors(9.52%). Different storage temperature and different storage time, white blood cell count(WBC) and platelet count(PLT) were significantly different(P<0.05). Peripheral red blood cell count(RBC) was lower than venous blood, PLT and WBC were higher than venous blood, the difference was statistically significant(P<0.05). Conclusion The incidence of errors in routine blood tests is relatively high. Taking targeted prevention and control measures based on the causes of common errors in routine blood tests can improve the accuracy of test results and help provide objective evidence for clinical diagnosis and treatment of disease.
