Antithyroid antibodies would be the best choice to identify an autoimmune inflammatory disease as it detects the presence of antibodies against the thyroid gland. Increased levels of thyroid hormones may be caused by autoimmune diseases such as Hashimoto's thyroiditis or Graves' disease, which can be detected through antithyroid antibody testing. The other options (isotopic thyroid scan, TSH level, serum calcitonin, and ultrasonography) would not necessarily identify an autoimmune inflammatory disease as the cause of increased levels of thyroid hormones.
