What is the Clinical Significance of Thyroglobulin?
The measurement of thyroglobulin levels in the blood can be an important diagnostic tool. Elevated levels of thyroglobulin can indicate a variety of thyroid conditions, such as thyroid cancer, thyroiditis, or Graves' disease. Conversely, low levels can be associated with hypothyroidism.
Additionally, thyroglobulin is often used as a tumor marker in patients who have undergone treatment for thyroid cancer. Monitoring thyroglobulin levels can help detect recurrent or residual disease.
