Information: Triiodothyronine (T3) is the biologically active form of
thyroid hormone that is responsible for the effects of thyroid hormones
on the various target organs. Only a small fraction of circulating T3
is derived from the thyroid. The T3 concentration in serum thus
reflects the functional status of the peripheral tissues rather than
the secretory performance of the thyroid. A reduction in the
conversion of T4 to T3 results in a decrease in the T3 concentration.
This occurs under the influence of drugs such as propranolol,
glucocorticoids or amiodaron and in a variety of conditions associated
with non-thyroidal illness (NTI).
