What is a biological age test?

A biological age test assesses how old your body is biologically compared to your chronological age based on various health markers. The test mentioned by Dr. David Sinclair involves measuring biological age through a mouth swab to predict future health and lifespan. This method can also track health improvements or declines, helping individuals optimize their longevity and quality of life 1.

Multiple methods and technologies may be used in biological age testing. Some measure tissue and cellular aging, while others focus on genetic, metabolic, or proteomic factors to gauge an individual's health status and potential longevity. The goal is to provide actionable insights that can guide lifestyle choices and interventions to optimize one's health 2.
