The reference values (norm) of thyroglobulin concentration in blood serum are 3-42 ng / ml (μg / l).
Thyroglobulin, the precursor of thyroid hormones T 3 and T 4, is used as a marker of tumors in the thyroid gland, and in patients with a distant thyroid gland or treated with radioactive iodine, to evaluate the effectiveness of the treatment. Relapses of benign and malignant tumors of the thyroid gland are accompanied by an increase in the concentration of thyroglobulin in the blood in most patients. The concentration of thyroglobulin is increased in patients with subacute thyroiditis, as well as in patients with relapses of chronic nonspecific thyroiditis.
Diseases and conditions in which the concentration of thyroglobulin in the blood serum changes
