These tests are not for thyroid function.
You need to have FREE T4, FREE T3 and TSH done for thyroid function.
FT4 is the only one I can see by your post.
What was the reference range on the C-Reactive protein and FT4?
I agree that these are not thyroid function tests. As Deb stated, get the FREE T3, FREE T4, and add a TSH.
Please post the results when you get them, along with the reference ranges from your lab report, as these are most important.
What symptoms do you have, other than throat pain?
