From: Evaluation of the thyroid characteristics of patients with growth hormone-secreting adenomas
TSH, FT3, and FT4 were measured in GH-secreting adenoma and NF pituitary adenoma groups. Levels of TSH and FT3 were significantly increased while that of FT4 did not change significantly in the GH-secreting adenoma group compared with the NF pituitary adenoma group. **P < 0.01. GH: growth hormone; NF: non-functioning; TSH: thyroid-stimulating hormone; FT3: free triiodothyronine; FT4: free thyroxine
