newly diagnosed thyroid issues
Our 15 year old son was recently diagnosed with hypothyroidism. His thyroxine free level is 0.358, and his TSH level is 100.00. According to his lab work TSH should be between 0.27-4.2, so 100.00 is extremely high. I understand how the hormones work and understand that with a low t3 and t4 his TSH should be elevated, but this high? His doctor is running more tests. What could cause his TSH level to be raised this high?
