The Dr Vahe Longevity Assessment is a preventative health and wellness service. The Blood Age Score and biological-age estimate are tools to communicate and track your health, not a medical diagnosis. This service does not replace NHS screening programmes or care from your GP. Results are interpreted by a GMC-registered doctor.
