Healthy ageing is mostly downstream of a small number of biological processes: cardiometabolic health, chronic low-grade inflammation, hormonal balance, and adequate nutrient status. Tracking the biomarkers behind these gives you the longest runway to act.
The longevity-relevant biomarkers
Cardiometabolic: HbA1c, fasting insulin, lipid profile. Inflammation: hs-CRP. Hormonal: thyroid, sex hormones, cortisol. Nutrient status: vitamin D, B12, ferritin. Organ function: liver and kidney panels.
Why this set?
These are the markers most strongly linked to long-term health outcomes in observational studies and clinical practice. Catching unfavourable trends early means lifestyle adjustment, supplementation or medical intervention has more time to work.
What to track over decades
Trends matter more than single readings. An LDL of 3.4 mmol/L is in range, but if it has risen from 2.6 mmol/L to 3.4 mmol/L over 5 years, that trend is worth watching. Same for HbA1c, hs-CRP, and many others. Annual baseline testing gives you the data to see trends.
What testing does not replace
Lifestyle is the foundation. Sleep, movement, food, social connection, purpose. Biomarkers are how you check that lifestyle is doing what you hope it is doing.

Frequently asked questions
Why annual testing rather than every few years?
Trends become visible with more data points. Annual testing makes subtle shifts (like a slow climb in HbA1c) detectable years before they cross diagnostic thresholds.
Is there a single best longevity test?
No. The picture is multifactorial. The Longevity Panel is built around the most useful combination, but no single biomarker captures healthy ageing on its own.
