This study compares the accuracy of the free thyroxine index and free serum thyroxine radioassay in evaluating the metabolic status of 36 euthyroid women, 17 of whom were taking oral contraceptive drugs. Results indicate that the free thyroxine index does not uniformly compensate for estrogen-induced elevations in total serum thyroxine concentrations and that the free serum thyroxine is the test of choice in assessing the functional thyroid status of women taking oral contraceptive drugs.
本研究比较了游离甲状腺素指数和游离血清甲状腺素放射测定法在评估36名甲状腺功能正常女性代谢状态方面的准确性,其中17名女性正在服用口服避孕药。结果表明,游离甲状腺素指数不能一致地补偿雌激素引起的血清总甲状腺素浓度升高,游离血清甲状腺素是评估服用口服避孕药女性甲状腺功能状态的首选检测方法。
