一、甲状腺机能检查项目繁多,主要项目如下: 1.反映血液循环中激素水平的项目血清促甲状腺素(TSH)、甲状腺素(T_4)、三碘甲状腺素原氨酸(T_3)、T_3树脂摄取率(T_3RU)、游离T_4指数(FT_4I)、游离T_4(FT_4)和游离T_3(FT_3)等。这些试验绝大多数是采用放射免疫测定法。 2.反映垂体-甲状腺轴机能关系的项目甲状腺片(或T_3)抑制试验及促甲状腺素释放激素(TRH)兴奋试验等。 3.反映甲状腺激素合成的项目甲状腺摄碘率和过氯酸盐试验。 4.反映甲状腺激素对靶组织作用的项目基础代谢率(BMR)、跟腱反射时间测定(ART)、血清胆固醉及心电图等。近10年来由于放射免疫分析血液循环中激素水平的方法迅速推广应用,给甲状腺机能检查带来划时代的变革。过去常用的甲状腺摄碘率,虽然目前
First, the thyroid function test a wide range of projects are as follows: 1. To reflect the blood levels of hormones in the project serum thyrotropin (TSH), thyroxine (T_4), triiodothyronine (T_3), T_3 resin intake Rate (T_3RU), free T_4 index (FT_4I), free T_4 (FT_4) and free T_3 (FT_3) and so on. The vast majority of these tests using radioimmunoassay. Thyroid tablets (or T_3) inhibition test and thyrotropin-releasing hormone (TRH) excitability test, which reflect the relationship between pituitary-thyroid axis function. 3. Thyroid hormone uptake rate and perchlorate test reflecting thyroid hormone synthesis. 4. The project basal metabolic rate (BMR), Achilles tendon reflex time (ART), serum cholesterol and ECG, etc., which reflect the effect of thyroid hormone on the target tissue. Nearly 10 years because of radioimmunoassay blood levels of hormone in the rapid promotion of methods to the thyroid function tests to bring about a landmark change. In the past, thyroid iodine uptake rates, though at the moment
