近年来,在有关甲状腺功能测定的认识方面有了真正的进展。实际工作中令人信服地说明了测定游离甲状腺素,特别是测定游离甲状腺素指数,对临床鉴别甲状腺疾病的筛选具有很大的实用价值。 在这一时期中,有许多文章指出甲状腺功能试验的异常可以由非甲状腺疾病所致,而且,用不同的方法测定同一种游离激素浓度时,有时会出现完全不同的结果。根据这些事实所得出的结论是:正常的游离甲状腺素指数实际上可以排除甲状腺功能低下或甲状腺功能亢进;而异常的结果却即可以
In recent years, there has been real progress in understanding thyroid function tests. Practical work convincingly illustrates the determination of free thyroxine, in particular the determination of free thyroxine index, for the clinical screening of thyroid disease has great practical value. During this period, many articles pointed out that the abnormality of thyroid function test can be caused by non-thyroid disease. And when different methods are used to determine the same concentration of free hormone, completely different results sometimes occur. Based on these facts, it is concluded that the normal free thyroxine index can actually exclude hypothyroidism or hyperthyroidism, whereas the abnormal result can be
