The thyroid gland makes T4 in response to thyroid-stimulating hormone (TSH). TSH is made by the pituitary gland in your brain. T4 is found in the body in 2 forms: free T4 and bound T4. … Because T4 is converted into another thyroid hormone called T3 (triiodothyronine), free T4 is the more important hormone to measure.
