ODM Best CA125 test Reagent Factory – T4 – Aehealth

The determination of serum or plasma levels of Triiodothyronine (T3) is recognized as an important measurement in the assessment of thyroid function.

Its effects on target tissues are roughly four times more potent than those of T4. Of the thyroid hormone that is produced, just about 20% is T3, whereas 80% is produced as T4.

T3 and T4 are regulated by a sensitive feedback system involving the hypothalamus and the pituitary gland.

Approximately 99.7% of the T3 circulating in the blood is bound to plasma proteins: TBG (30- 80%), TTR/TBPA (9- 27%) and Albumin (11- 35%).

Only 0.3% of the circulating T3 is free (unbound) and biologically active. T3 plays an important role in the maintenance of the euthyroid state.

Total T3 measurements can be a valuable component in diagnosing certain disorders of thyroid function.
