Dual isotope assays for thyroid function are performed by carrying out a radio-immunoassay for two of thyroxine (T4), tri-iodothyronine (T3), thyroid stimulating hormone (TSH), and thyroxine binding globulin (TBG) wherein a version of one of the thyroid components, preferably T4 or T3 is labelled with Selenium-75 and the version of the other thyroid component is labelled with a different radionuclide, preferably Iodine-125.
甲状腺功能的双同位素测定是通过对甲状腺素(T4)、三碘甲状腺原氨酸(T3)、甲状腺刺激素(TSH)和甲状腺素结合球蛋白(TBG)的两种成分进行放射免疫测定来完成的。其中,首选T4或T3的版本用硒-75标记,另一种甲状腺成分的版本用不同的放射性核素标记,首选碘-125。
