ANTI-TG: Thyroglobulin Antibodies (TGab)
The presence of auto-antibodies against thyroglobulin indicates possible inflammation of the thyroid gland (Autoimmune thyroiditis).
ANTI-TG
High levels are found in Hashimoto’s thyroiditis (85%), thyroid carcinoma (45%) and Grave’s disease (30%). Low levels of antibodies are found in greater than 10% of euthyroid patients, and may also be present in many autoimmune conditions including pernicious anaemia, SLE, and some chromosomal disorders such as Turner’s syndrome and Down’s syndrome.
