For a group of normal medical students, we examined the effect of posture on the concentration of a number of constituents in plasma. On standing, there is a significant increase in plasma total protein, albumin, calcium, alkaline phosphatase, bilirubin, and cholesterol--all proteins or substances bound to protein. Although it is possible to make an allowance for postural variations in plasma calcium, no correction is possible for changes in protein concentrations and care is needed whenever the precise values are important, as in the follow-up of patients with the nephrotic syndrome.
对于一组正常医学生，我们研究了姿势对血浆中多种成分浓度的影响。站立时，血浆总蛋白、白蛋白、钙、碱性磷酸酶、胆红素和胆固醇（所有蛋白质或与蛋白质结合的物质）显著增加。虽然可以考虑血浆钙的姿势变化，但蛋白质浓度的变化无法校正，并且每当精确值很重要时（如在肾病综合征患者的随访中），都需要谨慎对待。
