A simple and convenient method of transport of serum in the form of protein disc on water resistant medium is described. The method was used to study the stability of thyroxine (T4), cortisol, thyroid stimulating hormone (TSH), parathormone (PTH) and insulin. The mean recoveries of these hormones were between 98 and 100%. The standard deviations of duplicates of assays for protein disc samples were comparable to that of serum samples except in assays using enzyme immunoassay techniques. The correlation coefficients of the results between the serum and protein disc samples were satisfactory ranging from 0.86-0.99. The proposed method could be used for interlaboratory referral of serum.
描述了一种在防水介质上以蛋白质圆盘形式运输血清的简单便捷方法。该方法用于研究甲状腺素(T4)、皮质醇、促甲状腺激素(TSH)、甲状旁腺激素(PTH)和胰岛素的稳定性。这些激素的平均回收率在98%至100%之间。蛋白质圆盘样品重复检测的标准差与血清样品的标准差相当,但使用酶免疫分析技术的检测除外。血清和蛋白质圆盘样品结果的相关系数令人满意,范围为0.86 - 0.99。所提出的方法可用于实验室间血清的送检。
