OBJECTIVES
We studied the stability of 33 analytes related to clinical chemistry, bone, and vitamin metabolism, after storage in serum separator tubes (SST).
DESIGN AND METHODS
Blood was collected from 6 subjects using SST tubes. Some serum remained in the tube in contact with the barrier gel and was stored at -80 degrees C for 12 mo.
RESULTS
Clinically significant changes occurred only in 1,25-dihydroxyvitamin D and retinol-binding protein.
CONCLUSIONS
Freezing SST tubes before sample analysis is a viable option for some analytes.
目的
我们研究了与临床化学、骨骼和维生素代谢相关的33种分析物在血清分离管（SST）中储存后的稳定性。
设计与方法
使用SST管从6名受试者采集血液。一些血清留在管中与隔离胶接触，并在-80℃下储存12个月。
结果
临床上有显著变化的仅为1,25-二羟基维生素D和视黄醇结合蛋白。
结论
对于某些分析物，在样本分析前冷冻SST管是一种可行的选择。
