Triiodothyronine Test

The triiodothyronine test is a method for detecting thyroid dysfunction, which is based on analyzing the rate of triiodothyronine uptake by red blood cells. This test is used to diagnose hyperthyroidism and hypothyroidism, conditions associated with thyroid dysfunction.

Triiodothyrine (T3) is one of the thyroid hormones and plays an important role in metabolism. With hyperthyroidism, the level of T3 in the blood is increased, which leads to an acceleration of the uptake of this hormone by red blood cells. This manifests itself in the fact that red blood cells absorb T3 faster than under normal conditions.

In hypothyroidism, on the contrary, T3 levels decrease, which slows down the process of uptake by red blood cells. As a result, red blood cells absorb T3 more slowly.

The triiodotinine test uses radioactive iodine, which is labeled and injected into the patient's blood. The rate at which this iodine is absorbed into red blood cells over a period of time is then measured. If the absorption rate is higher than normal, this indicates elevated T3 levels and indicates hyperthyroidism. If the absorption rate is lower, this indicates hypothyroidism.

In addition, the triiodothyrine test can be used to determine the effectiveness of treatment for thyroid diseases such as hypothyroidism or hyperthyroidism, as well as to monitor thyroid health in patients already undergoing treatment.

Thus, the triiodotin test is an important tool in the diagnosis and control of thyroid diseases. It allows you to quickly and accurately determine the presence of disturbances in the functioning of this gland and prescribe the necessary treatment.

The triiodothyroid test is a method for analyzing hormone levels in the blood, used to evaluate the functioning of the thyroid gland and identify pathologies in its functioning. The method is based on accelerating the uptake of triiodothione (a radioactive isotope of iodine) bound to labeled iodine into erythrocytes in case of hyperthyroid thyroid dysfunction. In hyperthyroid diseases, the metabolism of hormones is accelerated, and in hypothyroid diseases it is slower, which leads to a change in the absorption rate of the radiotaster.
