antithyroid antibody

antithyroid antibody

Thyroid antibody Any antibody directed against 'self' antigens, which may be either cellular components–eg antimicrosomal antibodies or proteins–eg thyroglobulin, of thyroid origin, that are often present in autoimmune diseases; ATAs damage the thyroid and occur in 40-90% of Pts with chronic thyroiditis, Graves' disease or thyrotoxicosis, Hashimoto's thyroiditis, hypothyroidism; ATAs may also be ↑ in pernicious anemia, rheumatoid arthritis, and SLE Ref range Titers < 1:32-antithyroglobulin, and < 1:100-antimicrosomal are negative. See Antimicrosomal antibodies, Antithyroglobulin.
