Re: Conflicting labs confused
None of those tests is for Graves'. The TSI antibody test is the one used for that.
The ANA is positive because the thyroid antibodies are. ANA is a non-specific test. Almost any autoimmune disorder out of the 80+ identified ones might show a positive ANA. Specific antibody testing - such as anti-thyroperoxidase or anti-thyroglobulin - is needed to identify the specific AI disease.
On the face of it, it's Hashimoto's. But that's less important than the fact that your Synthroid dose needs to be increased. You're hypothyroid at the moment. The reason for it - the Hashi's - is far less important. If you're having symptoms [You don't say?], it's because your hypothyroidism is not being optimally treated.
