SelectedThe Longevity Foundations Panel is an early-intervention blood test designed to uncover silent biological ageing processes long before clinical disease develops. Rather than reacting to symptoms, this panel focuses on core pathways known to accelerate ageing, cardiovascular risk, and metabolic decline.
It is ideal as a starting point for longevity optimisation, healthspan tracking, and preventative strategies, even in people who feel “well” on the surface.
Identify silent ageing drivers before symptoms appear.
Modern ageing is often driven by low-grade inflammation, impaired methylation, metabolic stress, and dysregulated growth signalling. These changes can be present for years before diagnosis of cardiovascular disease, diabetes, or neurodegeneration.
This panel highlights those risks early, allowing corrective action when it matters most.
Homocysteine
A marker of methylation efficiency and vascular ageing. Elevated levels are linked to cardiovascular disease, cognitive decline, and accelerated biological ageing.
IGF-1
Reflects growth signalling balance. Excessive IGF-1 may accelerate ageing, while low levels may impair repair and resilience. This marker helps assess the growth vs longevity trade-off.
hs-CRP
A highly sensitive inflammation marker. Even mildly elevated levels indicate chronic low-grade inflammation, a major driver of ageing and disease.
Full Blood Count
Provides insight into immune health, oxygen delivery, and systemic stress.
Liver Function Tests
Ensures metabolic processing and detox capacity are functioning optimally.
Lipid Profile
Total Cholesterol, HDL, LDL, Triglycerides – assesses cardiovascular and metabolic risk.
Glucose Control
HbA1c and fasting glucose – identifies early insulin resistance and glycaemic stress.
Methylation & repair nutrients
Vitamin B12 and Folate – essential for DNA repair, methylation, and homocysteine control.
Ageing rarely starts with symptoms. The earliest changes occur at a biochemical level.
This panel is recommended if you:
• Want to optimise healthspan, not just lifespan
• Have a family history of cardiovascular or metabolic disease
• Are interested in preventative, data-driven longevity
• Want a baseline before deeper longevity or peptide testing
• Feel “fine” but want to identify hidden risks
• Are managing stress, inflammation, or metabolic health
Common hidden drivers this panel can uncover:
• Chronic low-grade inflammation
• Impaired methylation
• Early insulin resistance
• Unfavourable lipid patterns
• Growth signalling imbalance
Expanded benefit explanation
By targeting the root biochemical processes of ageing, this panel allows early intervention at a stage where changes are most reversible.
We offer two UK-wide options:
Clinic testing
• Choose your nearest UK clinic
• Blood sample taken by a clinician
• Samples analysed by an accredited laboratory
• Results delivered securely
Home visit (+£60)

• Samples sent to laboratory
• Results delivered securely
Both services are available UK-wide.
May indicate early vascular ageing, inflammation, metabolic stress or impaired methylation requiring optimisation.
Suggest a favourable longevity profile with balanced repair and growth signalling.
Highlight areas where lifestyle, nutrition or clinical intervention may significantly reduce long-term disease risk.
UK laboratory reference ranges are provided with all results.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
