Description
Estimated cost for Thyroglobulin Antibody at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The main clinical uses of the Thyroglobulin Antibody test include diagnosing and monitoring autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease, assessing the risk of post-surgical hypothyroidism in patients with thyroid cancer, and evaluating the effectiveness of treatment in these conditions. It is also useful in predicting the likelihood of developing thyroid dysfunction in individuals with a family history of autoimmune thyroid disorders.
Normal Range
The normal range for Thyroglobulin Antibody (TgAb) is typically less than 4.11 IU/mL, but this can vary slightly depending on the laboratory and the specific method used for testing.
Low Values - Possible Causes
Low levels of TgAb are generally not a concern and do not usually indicate any specific condition. However, if TgAb levels are undetectable or very low in a patient with known thyroid disease, it might suggest that the autoimmune process is not active at the time of testing, or the individual may not have an autoimmune thyroid disorder.
High Values - Possible Causes
High levels of TgAb can be caused by: 1. Hashimoto's thyroiditis, 2. Graves' disease, 3. Other autoimmune thyroid diseases, 4. Postpartum thyroiditis, 5. Certain types of thyroid cancer, especially in patients who have had their thyroid removed and are being monitored for recurrence.
