影响血常规检验结果的相关因素分析

Analysis of related factors influencing the routine blood test results

目的探讨影响血常规检验结果的相关因素,确保检验结果的准确性。方法观察不同采血部位及采血后不同检测时间对结果的影响。结果手指血的白细胞计数、红细胞计数、血红蛋白水平明显高于静脉血,而血小板计数较静脉血低,差异均有统计学意义(P<0.05)。≥6h检测的血液标本血小板计数较立即检测和小于6h检测明显降低,差异有统计学意义(P<0.05)。结论制度的完善、操作的规范、标本质量的提高,都有助于提高血常规检验结果的准确性。

Objective To explore the influencing factors of routine blood test results in the laboratory ,to ensure the accuracy of test results .Methods The influence of the different area of drawing blood and different testing time after blood collection were ob-served .Results The leukocyte count ,red blood cell count ,hemoglobin level of finger blood were obviously higher than those of venous blood ,and the platelet count was lower than that of venous blood ,the difference was statistically significant（P〈0 .05） .≥6 h test specimens of blood platelet count was significantly lower ,compared to immediate detection and less than 6 h ,the difference was statistically significant（P〈0 .05） .Conclusion The improvement of the system ,operation specification ,improving the quality of samples are helpful to improve the accuracy of test results .
