Kit ELISA 3T of Arghvan Teb Kavian Company is designed for quantitative measurement of total triiodothyronine or 3T Total in serum or plasma. This kit is supplied in a package of 96 tests by Arghvan Teb Kavian Company. Two hormones thyroxine (T4) and triiodothyronine (T3) are produced by the thyroid gland and enter the blood.

Only 20% of T3 hormone is made directly by the thyroid, and 80% is made by the 5-iodinase enzyme in tissues from removing an iodine atom from thyroxine. Because T3 has a shorter half-life compared to T4 (2 days compared to 7 days). Therefore, it seems that thyroxine acts mainly as a storage source and precursor of T3 hormone, which is the most biologically active form of thyroid hormones.

Like T4, the majority of T3 in the blood is also transferred bound to TBG, prealbumin and albumin proteins, but the affinity of TBG to T3 is lower compared to T4, so compared to thyroxine, there is a larger fraction of T3 in free form. ) 0.3% of T3 compared to 0.02% of T4. However, due to the daily production of three times more T4 than T3, the absolute amount of free T4 is greater than free T3.

The main driver of thyroid hormone production is thyrotropin hormone or TSH secreted from the pituitary gland, which is under the control of thyrotropin-releasing hormone (TRH) produced by the hypothalamus, both of which are under the feedback control of T3 and T4. Thyroid hormones enhance many intracellular actions and promote cell growth and differentiation.

Thyroid hormones increase oxygen consumption and ATP production, mitochondrial metabolism, synthesis and metabolism of carbohydrates, synthesis and breakdown of cholesterol and triglycerides (for example, through the regulation of LDL receptor expression in the liver), tissue sensitivity to catecholamines. . It also increases heart rate and contractility of heart muscles. In addition to the mentioned cases, thyroid hormones play an important role in regulating calcium and phosphorus metabolism, growth and development of fetuses and children.

In these people, TSH is usually in the reference range. Some drugs, such as amidarone or propranolol, inhibit the enzyme iodinase, reducing the environmental conversion of T4 to T3. In these people, despite the increase in T4, we see a decrease in T3 and normal or high TSH. In 95% of cases of toxic thyroid or thyrotoxicosis, the measurement of total or free T4 (and TSH) is sufficient for diagnosis, but in 2 to 5% of cases, an increase is observed only in T3 (T3 toxicosis or T3).
