Different procedures for the collection of blood for the determination of reference values in healthy adults have been subjected to practical testing. The Scandinavian Committee on Reference Values suggested that subjects lying in bed after an overnight sleep and ambulatory individuals, after 15 min of sitting in a chair, were two suitable and different reference populations. In forty subjects we found an increase from lying to sitting position of about 6.5% in the serum concentrations of proteins, enzymes and lipids. The corresponding increases for S-calcium and B-haemoglobin were approximately 3% whereas S-thyroxine, unexpectedly, changed by 11%. There were no significant changes of potassium and sodium values. For some constituents the changes were age and sex-dependent being greater in a group of elderly women as compared to a group of younger men. After 1 h of recumbency the concentrations of the constituents generally returned to those in the initial, lying position.
针对健康成年人参考值测定的不同采血程序已进行了实际测试。斯堪的纳维亚参考值委员会建议，经过一夜睡眠后卧床的受试者以及在椅子上坐15分钟后的非卧床个体，是两个合适且不同的参考人群。在40名受试者中，我们发现从卧位到坐位时，血清中蛋白质、酶和脂质的浓度大约增加了6.5%。血清钙和血红蛋白的相应增加约为3%，而血清甲状腺素出人意料地变化了11%。钾和钠的值没有显著变化。对于某些成分，这些变化与年龄和性别有关，老年女性组的变化比年轻男性组更大。躺卧1小时后，这些成分的浓度通常会恢复到初始卧位时的浓度。
