Biochemia Medica:对健康成人血清甲状旁腺素的生物学变化进行测量

2019-11-03 MedSci MedSci原创

在钙代谢紊乱的调查和管理中,甲状旁腺素(PTH)的测量是必不可少的。为了评估任何检测结果的重要性,必须考虑被测物的临床决策生物变异(BV)。因此,本研究的目的是确定血清甲状旁腺激素的BV参数。

在钙代谢紊乱的调查和管理中,甲状旁腺素(PTH)的测量是必不可少的。为了评估任何检测结果的重要性,必须考虑被测物的临床决策生物变异(BV)。因此,本研究的目的是确定血清甲状旁腺激素的BV参数。

在这项前瞻性BV研究中,研究人员为20名健康受试者每隔一周采集一次血液样本,一共为期10周。用电化学发光法测定血清“完整PTH”浓度。利用Fraser提出的方法估计生物变异参数。

研究发现,受试者内生物变异(CVI)、受试者间生物变异(CVG)、分析变异(CVA)、参考变异值(RCV)和个体指数(II)分别为21.1%24.9%3.8%59.4%0.8%。按性别分类分别测定受试者体内生物变异和CVG;并发现男性和女性分别为18.5%24.0%以及26.2%18.6%。计算出的理想精度和偏差目标分别为< 10.6%< 6.3%

本研究可能有助于血清PTHBV数据,因为它包括了在一段可接受的时间内足够多的男女志愿者。我们不建议使用基于人群的参考区间测定血清PTH浓度。参考值的变化对评价系列血清甲状旁腺激素检测结果有一定的参考价值。然而,在制定分析性能规范时,还应该根据性别对数据进行评估。
