long-acting thyroid stimulator

long-acting thyroid stimulator

 (LATS)

a substance occurring in the blood in hyperthyroidism, having a stimulating effect on the thyroid of longer duration than that of thyrotropin. It is associated with immunoglobulin IgG and may function as an autoantibody.

long-act·ing thy·roid stim·u·la·tor (LATS),

a substance, found in the blood of some hyperthyroid patients, which exerts a prolonged stimulatory effect on the thyroid gland; associated in plasma with the IgG (7 S γ-globulin) fraction and seems to be an antibody or, perhaps, an immune complex.

long-acting thyroid stimulator (LATS)

an immunoglobulin, probably an autoantibody, that exerts a prolonged stimulatory effect on the thyroid gland, causing rapid growth of the gland and excess thyroid function, resulting in hyperthyroidism. It is found circulating in the blood of 50% of people with Graves' disease.

long-act·ing thy·roid stim·u·la·tor

(LATS) (lawng'ak'ting thī'royd stim'yū-lā-tŏr)

A substance, found in the blood of some hyperthyroid patients, which exerts a prolonged stimulatory effect on the thyroid gland; associated in plasma with the immunoglobulin (7S γ-globulin) fraction and seems to be an antibody or, perhaps, an immune complex.

long-act·ing thy·roid stim·u·la·tor

(lawng'ak'ting thī'royd stim'yū-lā-tŏr)

A hematologic substance that exerts a prolonged stimulatory effect on the thyroid gland.

long-acting thyroid stimulator

an autoantibody directed against thyroid-stimulating hormone receptors in the thyroid; abbreviated LATS. Its occurrence is associated with hyperthyroidism in humans.
