Frequently Asked Questions
Chronological age is the single most significant risk factor for a range of chronic diseases and cellular degradation. Through the application of cutting-edge diagnostics, therapeutics and personalized lifestyle interventions, Chi Longevity’s mission is to slow down, and in some cases reverse, the biological ageing process. Ageing is now being treated as a disease.
Your journey starts before you get to the clinic with comprehensive pre-appointment assessments. At the clinic, your experience lasts three to four hours as you undertake a thorough review with our multidisciplinary team of doctors, nurses, dietitians, psychologists and health coaches. The aggregated results of these tests are available after six to eight weeks, and a comprehensive reveal consultation is scheduled. A detailed report is provided, and you enter a personalized multi-month program supported by our health coaches. You are then retested to determine how your biological age has been impacted.
Your review includes an extensive analysis of your blood biomarkers, genome, epigenetics, microbiome, and physical and mental capabilities. This allows us to provide you with the biological ages of your key organs or systems.
