Thyroid Function Test (T3, T4 and TSH)
What is Thyroid Function test?
An examination of the thyroid’s function is called a thyroid function test. Patients may undergo TFTs if they suffer from hyperthyroidism or hypothyroidism, or to monitor their thyroid suppression or hormone replacement therapy’s effectiveness.
The purpose of thyroid tests is to determine whether your thyroid is functioning properly and to determine whether you have hyperthyroidism or hypothyroidism. Thyroxine (T4) and triiodothyronine are produced by the thyroid, a little gland in your neck that resembles a butterfly (T3). Thyroid hormones influence almost every organ in the body and regulate how the body uses energy.
