fT3 (Free serum thyroxine - thyroid hormone)
Free T3 (fT3) is an active form of triiodothyronine (T3) – a hormone produced primarily in the thyroid gland. The effect of the free fraction of the T3 hormone is approximately 10-times higher than that of thyroxine. Many serious health conditions, such as cancer or a critical threat to life, may be accompanied with the low T3 syndrome; in such as case, the physiological levels of TSH and fT4 are tested at a decreased level of T3 (total and free).
