SelectedThe Longevity Core Metabolic & Cardiovascular panel is a strategically designed blood test focused on the highest-return biomarkers for longevity, metabolic health, and cardiovascular risk. It targets insulin resistance, lipid-driven heart risk, inflammation, hormone balance, thyroid function, nutrient deficiencies, and organ clearance.
This panel is especially valuable for individuals who are overweight, vegetarian/plant-based, metabolically stressed, or proactively optimising long-term health.

Longevity is driven less by rare genetics and more by metabolic control, inflammation, hormone balance, and nutrient sufficiency. This panel targets the most actionable systems linked to early ageing, cardiovascular disease, diabetes, and hormonal decline.
You may benefit from this panel if you:
Want to assess insulin resistance early
Are focused on cardiovascular disease prevention
Follow a vegetarian or plant-based diet
Have fatigue, weight gain, or poor body composition
Want to optimise hormones safely
Are planning lifestyle or peptide-based interventions
Prefer a focused, high-ROI longevity panel
Early insulin resistance detection
Glucose, insulin, HbA1c, and HOMA-IR included.
Advanced cardiovascular risk insight
Lipids, hs-CRP, and optional ApoB go beyond basics.
Inflammation & ageing insight
hs-CRP highlights systemic risk.
Hormone optimisation foundation
Androgens, adrenal, and pituitary markers included.
Thyroid-metabolism alignment
Prevents missed metabolic drivers of fatigue and weight gain.
Vegetarian nutrient gap detection
B12, iron, zinc, vitamin D commonly missed.
Liver & kidney clearance safety
Supports long-term metabolic and supplement strategies.
High-ROI longevity screening
Focused without unnecessary overtesting.

Both services are available UK-wide.
May indicate insulin resistance, hormonal suppression, nutrient depletion, inflammation, or impaired organ clearance affecting long-term health.
UK reference interpretation:
Abnormal: Outside laboratory reference ranges
Markers within range suggest good metabolic control, low inflammatory burden, and reduced long-term cardiovascular risk.
UK reference interpretation:
Optimal: Within laboratory reference ranges
Raised insulin, triglycerides, hs-CRP, GGT, or ApoB suggest higher cardiometabolic and ageing risk and benefit from early intervention.
UK reference interpretation:
High risk: Above laboratory reference ranges

WhatsApp UsFollow these guidelines for accurate 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.
