How Accurate (and useful) is an FT3 Bloodtest?
People often ask me questions like:
"Why do I feel terrible when my FT3 is actually mid range or even a bit above mid range?"
"My doctor says that my FT3 is fine, and I don't need T3 or Natural Desiccated Thyroid but I have all the symptoms of hypothyroidism. How can that be?"
"If my FT3 is ok and my rT3 isn't that high but I feel terribly hypothyroid and have done since I had Hashimoto's thyroiditis then could T3 really help me?"
