What does TFT mean?
a group of blood tests that assess the thyroid gland
TFT stands for thyroid function test, a group of blood tests used to check how well the thyroid gland is working. The panel usually includes TSH along with the thyroid hormones, mainly free thyroxine (free T4) and sometimes free triiodothyronine (free T3). Together these results show whether the thyroid is normal, underactive, or overactive, and help distinguish where the problem lies. TFTs are used to diagnose and monitor conditions such as hypothyroidism and hyperthyroidism.
When is TFT used?
TFTs are ordered in primary care and endocrinology to diagnose and monitor thyroid disease.
