血清钴胺素放射核素稀释测定法是目前诊断钴胺素缺乏症常用的实验室检验方法。由于该法显示迅速,而人们又迫切期望准确快速诊断钴胺素缺乏症,它得到了广泛应用。两个问题需考察:(1)该测定法是否一准确方法(2)所测得的结果能否准确反映体内组织中钴胺素缺乏情况。本研究的目的即在于对此方法的应用做出评估。
Serum Cobalamin Radionuclide Dilution Assay is a commonly used laboratory test for the diagnosis of cobalamin deficiency. As the method shows rapid, and people are eager to accurate and rapid diagnosis of cobalamin deficiency, it has been widely used. Two questions need to be investigated: (1) whether the assay is an accurate method (2) whether the measured results accurately reflect the lack of cobalamin in the tissues of the body. The purpose of this study is to evaluate the application of this method.
