The effects on the concentrations of total cholesterol, high-density lipids (HDL), triglycerides and glycerol of temporary venous occlusion during blood sampling and changing body posture (lying and standing) were measured on 20 healthy male volunteers (mean age 25 [21-27] years) with normal blood-lipid levels. Venous occlusion in the upper arm increased the concentration of lipids in the antecubital vein, by 8% after five min and 37% after 15 min. Initial levels were restored 10 and 15 min after the occlusion. Blood-lipid levels were similarly raised on standing up again. After 5 min they had risen by about 9%, after 15 min by 16%. After renewed recumbency the levels were up from the initial values by 5% after 10 min and by 3% after 15 min (P less than 0.01). The concentration of free glycerol on the whole varied randomly, but there was a statistically significant rise after 10 and 15 min standing. These results indicate that different techniques of blood sampling can influence the lipid concentrations in venous blood.
对20名血脂水平正常的健康男性志愿者（平均年龄25[21 - 27]岁）进行了血液采样期间临时静脉阻塞以及改变身体姿势（躺卧和站立）对总胆固醇、高密度脂蛋白（HDL）、甘油三酯和甘油浓度影响的测量。上臂静脉阻塞使肘前静脉中的脂质浓度升高，5分钟后升高8%，15分钟后升高37%。阻塞后10分钟和15分钟恢复初始水平。再次站立时血脂水平同样升高。5分钟后升高约9%，15分钟后升高16%。再次躺卧后，10分钟后水平比初始值升高5%，15分钟后升高3%（P小于0.01）。游离甘油的浓度总体上随机变化，但站立10分钟和15分钟后有统计学上的显著升高。这些结果表明，不同的血液采样技术会影响静脉血中的脂质浓度。
