Thyroglobulin Antibodies (TgAb)
Helps diagnose autoimmune thyroid diseases. Targets thyroid proteins.
What it tests: Antibodies that signal the immune system is attacking thyroid tissue.
Why it is important: Often appear years before thyroid hormones move out of range, giving an early window for intervention. Identifying autoimmune activity early lets us address upstream drivers before the thyroid is meaningfully damaged.
