You really need an FT3 test to see what your body is actually doing with the levo.

Did you take your levo before the test..? Were the tests all done at the same time of day..?

Can I ask if you are taking the levo with water only, at least 30 mins to 1 hour before food..?

Which levo? Do you always get the same one..?

Have you had other tests...?
