good luck jackie -- keep us all posted
it's always good to get a second opinion - sometimes even a third or fourth

Hashimoto's is the most prevalent cause of hypothyroidism in the developed world, so there are those who simply "assume" that since a person is hypo, they have Hashi's. There are some people diagnosed with Hashimot's without elevated antibodies, though I've never really understood that.
It doesn't really matter that much, because the treatment is going to be the same, whether you have Hashi's or not, unless you have a pituitary issue or something.
The main time a diagnosis of Hashi's is good to have is in the beginning, because that will tell you that there may swings to hyper, and that as progression advances, you will need periodic changes in med dosages.
