The Thyroid Profile-Free (FT3, FT4, and TSH) is a test that measures three key thyroid-related markers:
FT3 (Free Triiodothyronine): The active form of thyroid hormone that regulates metabolism.
FT4 (Free Thyroxine): A precursor hormone that the thyroid produces, which is converted into T3 in the body.
TSH (Thyroid Stimulating Hormone): Produced by the pituitary gland, it stimulates the thyroid to produce T3 and T4.
This test helps assess thyroid function and diagnose conditions like hypothyroidism or hyperthyroidism by checking how much active thyroid hormone is available and how the thyroid is responding.
