--you've had elevated antibodies on testing before, and the endos did not think, despite the symptomology, that you had some variety of hypothyroidism? (What DID they think?)

From what I know, even if symptoms are minor, the autoantiboides are a gold standard, and an indication for treatment under present thinking even if TSH is (in the high end of) normal and T3/T4 are still within range--the thinking is this will help revent full-blown hypothyroid in the future.
