The influence which the position of the body (recumbent, sitting or erect) exerts on the hematologic laboratory indices was studied in 32 clinically healthy persons from both sexes, 19 to 48 years of age. Blood was taken by venepuncture in each of three positions. The analyses were carried out by a hematologic analyzer "H 1 Technicon". The differences of the results were processed by the pair analysis. The values of hemoglobin, hematocrit, erythrocytes, leucocytes and platelets increase with the change of the body position from recumbent to sitting and to erect and the differences are statistically significant. The changes are due to a reversible hemoconcentration and redistribution of the blood. The analysis of the differential count revealed that the greatest increase is of the neutrophils which is probably due to the mobilization of the pool of neutrophils which are nearest to the vascular wall, the process being parallel to the process of hemoconcentration.
对32名年龄在19至48岁之间的临床健康男女进行了研究，以探讨身体姿势（卧位、坐位或立位）对血液学实验室指标的影响。在三种姿势下分别通过静脉穿刺采血。使用血液分析仪“H 1 Technicon”进行分析。通过配对分析处理结果差异。随着身体姿势从卧位变为坐位再变为立位，血红蛋白、血细胞比容、红细胞、白细胞和血小板的值升高，且差异具有统计学意义。这些变化是由于血液的可逆性浓缩和重新分布所致。分类计数分析显示，中性粒细胞增加最多，这可能是由于最靠近血管壁的中性粒细胞池被动员，该过程与血液浓缩过程平行。
