The thyroid gland is a small, butterfly-shaped gland located in the neck.
A Thyroid Function Test (TFT) is a group of blood tests that measure levels of thyroid hormones and the hormone that stimulates them from the brain. It usually includes:
- TSH (Thyroid Stimulating Hormone): A hormone released by the pituitary gland to regulate thyroid activity.
