Thyroglobulin is a protein involved in the production of thyroid hormones. It is possible for antibodies from your own immune system to attack this protein rendering it dysfunctional.
Antibodies to thyroglobulin can result in symptoms of low thyroid such as fatigue, weight gain, dry skin and constipation. Conditions such as Hashimoto’s thyroiditis, lupus, rheumatoid arthritis, and autoimmune hemolytic anemia often have these antibodies present.
This test measures thyroglobulin antibody and is often used in conjunction with the thyroid peroxidase antibody. Doctors often use these tests to help them assess thyroid function, follow treatment for thyroid disease and differentiate between autoimmune conditions of the thyroid.
