In 16 hospitalized children aged 3 months to 14 years EDTA-blood samples were taken simultaneously from an anticubital vein and from a finger tip. Haematological measurements were subsequently performed in an Ortho ELT 800/WS analyzer. The thrombocyte count and the red cell indices were nearly identical in the two sets of samples. The 'capillary' erythrocyte count, haematocrit and haemoglobin values exceeded those of venous blood by 2%, and the mean 'capillary' total leukocyte count by about 20%. The relative frequency of lymphocytes, granulocytes and mononuclear cells did not alter between the two sets of samples. The significant differences demonstrated may in certain clinical settings be of medical importance. Their possible explanations are discussed.
对16名年龄在3个月至14岁的住院儿童,同时从肘前静脉和指尖采集乙二胺四乙酸(EDTA)抗凝血样本。随后在Ortho ELT 800/WS分析仪上进行血液学检测。两组样本中的血小板计数和红细胞指数几乎相同。“毛细血管”红细胞计数、血细胞比容和血红蛋白值比静脉血高出2%,“毛细血管”平均总白细胞计数高出约20%。两组样本中淋巴细胞、粒细胞和单核细胞的相对频率没有变化。所显示的显著差异在某些临床情况下可能具有医学重要性。对其可能的解释进行了讨论。
