About this service

Thyroglobulin test is a blood test used to measure the level of thyroglobulin protein, which is produced by the thyroid gland. This protein is an important indicator of thyroid function, especially in patients who have been treated for thyroid cancer or have undergone surgery to remove the gland. This test helps doctors assess the success of treatment and monitor any signs of disease recurrence. Elevated thyroglobulin levels after treatment may indicate remaining cancerous cells or abnormal thyroid activity. This test is recommended for individuals with a history of thyroid cancer, as well as patients showing symptoms of thyroid disorders such as changes in weight or energy levels. Overall, thyroglobulin testing is a valuable tool for diagnosing and monitoring thyroid health, helping doctors make informed treatment decisions.
