From: Transient hyperthyroidism after surgery for secondary hyperparathyroidism: a common problem
Time course of biochemical thyroid function markers in all patients undergoing parathyroidal surgery (n = 39). Mean value ± s.e.m. are shown (A-C). A) Time course of thyroid stimulating hormone (TSH, mU/L); the light grey box marks the normal range of TSH (0.4 to 4.0 mU/L). B) Time course of free thyroxine (fT4, ng/L); the light grey box marks the normal range of fT4 (8.0 to 18.0 ng/L). C) Time course of free triiodothyronine (fT3, ng/L); the light grey box marks the normal range of fT3 (2.0 to 4.2 ng/L).
