Tg Ab (Thyroglobulin Antibodies) is an important biomarker used in longevity research. Elevated levels of Tg Ab have been associated with autoimmune thyroid disorders and thyroid cancer, both of which can have significant impacts on overall health and lifespan. Monitoring Tg Ab levels can provide valuable insights into the health of the thyroid gland, which plays a critical role in metabolism and energy regulation. By tracking and addressing abnormalities in Tg Ab levels, longevity experts can help individuals maintain optimal thyroid function and reduce the risk of age-related thyroid complications, ultimately promoting healthy aging and longevity.
