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.
