目的探究末梢血采血方法和静脉血采血方法在临床血常规检验结果中的应用价值与差异。方法同时采集180例患者的末梢血和静脉血,采用Sysmex poc H-100i全自动血细胞分析仪检测血常规,并对比分析检测结果的差异性。结果末梢血白细胞(WBC)水平高于静脉血,血红蛋白(Hb)、红细胞(RBC)、红细胞压积(HCT)、平均红细胞体积(MCV)、平均红细胞血红蛋白浓度(MCHC)、血小板(PLT)水平均低于静脉血,差异有统计学意义(t=9.0658、3.0552、3.8982、15.7870、16.9151、5.0094、5.5333,P<0.05);两组平均红细胞血红蛋白含量(MCH)水平比较,差异无统计学意义(t=0.5297,P>0.05)。静脉血的稳定性明显高于末梢血样本检验。结论不同采集方法所检测的血常规结果有一定差异,除了需血量少、婴幼儿静脉采血难需进行常规检测外,临床上应尽量采集静脉血进行血常规检验,其检验结果的稳定性、准确性、可靠性均高于末稍血标本采集检验,临床检验价值更高,值得进一步应用。
Objective To explore the application value and difference of peripheral blood blood sampling methods and venous blood sampling methods in clinical blood routine test results. Methods Peripheral blood and venous blood samples were collected from 180 patients at the same time. The blood routine was detected by Sysmex poc H-100i automatic hematology analyzer. The differences of test results were analyzed. Results The peripheral WBC level was higher than that of venous blood, hemoglobin (Hb), erythrocyte (RBC), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCHC), platelet (T = 9.0658,3.0552,3.8982,15.7870,16.9151,5.0094,5.5333, P <0.05). There was no significant difference in mean erythrocyte hemoglobin (MCH) between the two groups (t = 0.5297, P> 0.05). The stability of venous blood was significantly higher than the peripheral blood samples tested. Conclusion There are some differences between the blood routine results detected by different collection methods. In addition to the small amount of blood needed and the venous blood sampling in infants and young children, which is difficult to be routinely tested, blood samples should be collected for venous blood tests in clinical practice. The stability, Accuracy and reliability are higher than the last blood specimen collection test, clinical examination of higher value, it is worth further application.
