Most doctors really don't understand thyroid issues AT ALL - you could have "normal" lab results and still have hypothyroidism. Plus, the typical lab panel for thyroid doesn't even include some of the key markers. There is a whole website dedicated to improperly diagnosed thyroid sufferers offering really detailed information (is overwhelming with info at first.). If interested, go to StopTheThyroidMadness dot com.

Wishing you good health!
