TPO Ab (Thyroid Peroxidase Antibodies) are biomarkers commonly used in longevity research and assessment. These antibodies are associated with autoimmune thyroid disorders, which can impact overall health and longevity. Elevated levels of TPO Ab may indicate an increased risk of thyroid-related conditions, such as hypothyroidism or Hashimoto’s disease, which can contribute to a variety of health issues and affect longevity. Monitoring TPO Ab levels can provide valuable insights into individual health and potential longevity considerations. As part of a comprehensive biomarker profile, TPO Ab can help inform personalized strategies for optimizing health and promoting longevity.
