TSH刺激试验,是给与TSH后观察甲状腺机能反应的检查方法。广泛用於原发性甲低和垂体性甲低鉴别及甲腺潜在能力的判断等方面。目前通常采用甲腺吸131Ⅰ率作为甲腺机能的指标,但有以下问题,①受碘摄入量的影响,②131Ⅰ放射性③需要特殊的仪器设备。作者从1974年以来即以给TSH前后观察血中T_4及T_3值的变化做为刺激试验的指标,已得到和吸131Ⅰ率测得相同的结果。本文则报告给与TSH前后测得尿中T_3的变化所得的结果。
TSH stimulation test is to observe the thyroid function after TSH test method. Widely used in primary hypothyroidism and pituitary hypothyroidism and the potential to determine the potential of glands and so on. At present, thyroid suction 131 I rate is usually used as an indicator of thyroid function, but the following problems, ① by the impact of iodine intake, ② ③ 131I radioactivity ③ require special equipment. Since 1974, the author has made measurements of the change of T_4 and T_3 in the blood before and after the TSH as indices of the stimulation test and has obtained the same result as that of the 131 I test. This article reports the results of changes in urine T_3 measured before and after TSH.
