CLIA Reagents of Thyroid (TT3)

TT3 has a higher biological activity than TT4, which is a necessary item to be tested for hypothyroidism and hyperthyroidism. So this kit is valuable for the early diagnosis of hyperthyroidism and monitoring the recurrent hyperthyroidism.

TT3 plays an important role in maintaining thyroid function. It has a higher biological activity than TT4, so it is very valuable to make early quantitative diagnosis of thyroid disease. treatment of patients TT3 levels were significantly higher for hyperthyroidism, high TBV and patients in treatment with hyperthyroidism; otherwise, lower for hypothyroidism, low TT3 syndrome and low TBG.

Serum total triiodothyronine TT3: The binding amount of T3 and protein in serum is more than 99.5%, so TT3 is also affected by the amount of TBG, and the change of TT3 concentration is often parallel to that of TT4; the increase of serum TT3 and TT4 concentrations is mainly seen in thyroid function In hyperthyroidism, together with FT3 and FT4, it can be used in the diagnosis, condition assessment, and curative effect monitoring of hyperthyroidism and hypothyroidism. However, in the early stage of hyperthyroidism and early recurrence, TT3 generally rises ly, about 4 times the normal level; TT4 rises slowly, only normal. Therefore, TT3 is a sensitive indicator for the observation of the curative effect of early Hashimoto's disease and the recurrence after drug withdrawal;

Elevated TT3 and TT4 can also be seen in active hepatitis, and decreased T3 and T4 in pregnancy can be seen in hypothyroidism; in hypothyroidism, decreased TT4 or FT4 is earlier than TT3 or FT3; decreased serum total T3 or FT3 is only seen in late disease or disease. Severe cases. In addition, the reduction of TT3 and TT4 can be seen in hypopituitarism, malnutrition, nephrotic syndrome, renal failure, and severe systemic diseases.
