julijkb As she already has a Hashi's diagnosis, there is no real benefit in repeating antibody tests.
What she can do is try to help reduce the antibodies by adopting a strict gluten free diet which many members find helps. Gluten contains gliadin which is a protein thought to trigger antibody attacks.

Supplementing with selenium L-selenomethionine 200mcg daily and keeping TSH suppressed also help reduce antibodies.
Some Hashi's information:
Having FT4 and FT3 tested will be helpful. It will tell whether the dose of Levo is enough, and will also show how well she is converting T4 to T3.
You are unlikely to get FT3 tested even if your GP requested it. It's the lab who decides and if TSH and FT4 are in range FT3 won't be done. It's possible to have them tested with a fingerprick test to do at home.
Also very useful would be to have vitamins and minerals tested. These all need to be at optimal levels, not just in range. You could ask the GP or, again, get them done with a fingerprick test:
Blue Horizon and Medichecks both do fingerprick tests.
If you want to include vitamins and minerals there is
Both the same price but sometimes on special offer.
If vitamins and minerals have already been tested by the GP (post results if they have) then for just TSH/FT4/FT3 look at
Once you have more results, post them with their reference ranges for members to comment.
