What are the Brightly Baseline+™ biomarkers?
Brightly Baseline+™ biomarkers are the 100+ measurable data points we use to understand how well you are ageing today and where future risks may be emerging.
They are drawn from your health history and questionnaire responses, physical assessments and performance measures, and clinical investigations including blood tests.
Together, they provide an objective, evidence informed picture of your health across physical health, cognition, mobility, nutrition, sleep, medication, and more. Your assessment is personalised to your health profile, with biomarkers included where clinically applicable. By analysing these indicators together, we identify risk early and track progress over time, supporting confident and proactive ageing.
