Thyroglobulin Antibody

This Thyroglobulin Antibody (TgAb) test is essential for understanding your thyroid health, especially concerning autoimmune activity. The presence of these specific antibodies in your blood can signal that your immune system is attacking the thyroid gland, which is often seen in conditions like Hashimoto's disease and Graves' disease. Doctors also rely on this blood panel to monitor patients after thyroid cancer treatment, as rising levels can indicate a cancer recurrence. If you have abnormal thyroid function tests or a history of thyroid issues, measuring TgAb provides crucial insight into potential damage or autoimmune involvement, helping your provider determine the best next steps for your care.
