Thyroglobulin antibodies are specific for thyroglobulin, a 660 kDa matrix protein involved in the process of thyroid hormone production. They are found in 70% of Hashimoto's thyroiditis, 60% of idiopathic hypothyroidism, 30% of Graves' disease, a small proportion of thyroid carcinoma and 3% of normal individuals.
Thyroglobulin (Tg) is a 660 kDa, dimeric glycoprotein produced by the follicular cells of the thyroid and used entirely within the thyroid gland. Tg is secreted and accumulated at hundreds of grams per litre in the extracellular compartment of the thyroid follicles, accounting for approximately half of the protein content of the thyroid gland.

Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy.
Thyroid disease is a medical condition that affects the structure and/or function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
They purified anti-thyroglobulin antibody from their serum and were able to conclude that these sick patients had an immunological reaction to human thyroglobulin. [4] From this data, it was proposed that Hashimoto's struma could be an autoimmune disease of the thyroid gland.
Thyroglobulin will also be measurable in a healthy thyroid, and will increase with inflammation, and may also be used to measure the success of thyroid removal or ablation. If successful, thyroglobulin should be undetectable. [85] Lastly, antibodies against components of the thyroid, particularly anti-TPO and anti-thyroglobulin, can be measured.
Ingestion of thyroid hormone also suppresses thyroglobulin levels helping to differentiate thyrotoxicosis factitia from other causes of hyperthyroidism, in which serum thyroglobulin is elevated. Caution, however, should be exercised in interpreting thyroglobulin results without thyroglobulin antibodies, since thyroglobulin antibodies commonly ...
The most common methods for diagnosing de Quervain thyroiditis are clinical and test results. [2] Elevations of C-reactive protein and erythrocyte sedimentation rate are laboratory features of the condition. [3] While typically normal, the blood leukocyte count may be slightly increased. There may be anemia that is normochromic and normocytic.
