i-Chroma T3 (3,5,3′ Triiodothyronine)

The thyroid gland produces both T3 and T4 hormones.Most of the T3 in the body binds to protein. The T3 that doesn’t bind to protein is called free T3 and circulates unbound in your blood. T3 plays an important role in the maintenance of the euthyroid state.

T3 measurements can be a valuable component in diagnosing certain disorders of thyroid function. Potential thyroid disorders include:

  • Hyperthyroidism: when your thyroid produces too much thyroid hormone
  • Hypopituitarism: when your pituitary gland doesn’t produce normal amounts of pituitary hormones
  • Primary or secondary hypothyroidism: when your thyroid doesn’t produce normal amounts of thyroid hormones
  • Thyrotoxic periodic paralysis: when your thyroid produces high levels of thyroid hormones, resulting in muscle weakness
