The T3 resin uptake (T3RU) is used as an indirect measure of serum thyroid hormone binding capacity, and the Free T4 index (FT4I), derived from the T4 and T3RU, corrects estimates of T4 for serum binding abnormalities.

2024年2月28日 · The T3RU test measures the level of proteins that carry thyroid hormone in the blood. This can help your health care provider interpret the results of T3 and T4 blood tests. Because tests called the free T4 blood test and thyroxine binding globulin (TBG) blood tests are now available, the T3RU test is rarely used these days.

A T3 resin uptake (also called a T3 uptake or T3RU) is a blood test performed as part of an evaluation of thyroid function. The T3 resin uptake is used by doctors to estimate the amount of TBG in the blood, and how much T4 and T3 in the blood …

In this article, we will review the steps in performing this test, pathophysiologic principles underlying the test and some cases studies. How is the Resin T3 Uptake test performed? The test consists of adding triiodothyronine (T3) labeled with radioactive iodine (either 125-I or 131-I isotopes) to the patient’s serum.

T3摄取试验（I-T3RUR）是基于患者血清中有效的结合位点与一种结合甲状腺激素的树脂之间竞争已知量的标记T3。 当血清中TBG浓度不正常时，树脂对标记T3的摄取与T4呈相反变化。 在这试验中使用的是放射性标记T3，而T4与TBG的结合比T3牢固，因此认为该试验测定的是TBG容量更为合适。 甲状腺激素（TH）进入血液后，绝大部分与血液中载体蛋白（主要是TBG）结合；TBG与标记TH的结合率决定于它被TH饱和的程度（即自由TBG容量）、血浆中TH的浓度和TBG总容 …

t3ru，也称为t3摄取或t3树脂摄取，是一种血液测试，用于评估甲状腺功能。 其原理是基于患者血清中有效的结合位点与一种结合甲状腺激素的树脂之间竞争已知量的标记T3。
