Your body holds the answers; we make them visible.
Uncover the hidden signals that shape your energy, performance, and longevity.
Our advanced diagnostic suite translates complex biochemistry into actionable insight, empowering you to take control of your health before symptoms appear.
Our Diagnostics First Approach
The Science Behind Your Health
At The National Longevity Clinic, diagnostics are not a prerequisite for entry. They are the foundation of every programme we design. We don't wait for symptoms. We focus on prevention, uncovering what your body is signaling long before disease develops.
Our approach merges functional medicine, genetic science, and clinical cardiology into one cohesive model. We examine your biology through five interconnected dimensions:
- Biochemistry: Nutrient, hormonal, and inflammatory balance.
- Genetics & Epigenetics: Predispositions that influence metabolism and ageing.
- Microbiome Health: The gut ecosystem shaping immunity, energy, and mood.
- Performance Metrics: Cardiovascular efficiency, oxygen capacity, and resilience.
- Structural Integrity: Bone, organ, and tissue health through advanced imaging.
By analysing these layers together, our specialists identify subtle patterns of imbalance and create a measurable roadmap for vitality and longevity.
Comprehensive Functional Blood Panels
Our most advanced testing platform analyses over 250 biomarkers, including hormones, micronutrients, inflammatory markers, and cardiovascular indicators.
This helps in early identification of nutrient deficiencies, insulin resistance, thyroid dysfunction, inflammation, and lipid imbalance.
DNA & Genetic Insight Testing
Using next-generation sequencing, we decode the genetic factors that influence your metabolism, detoxification pathways, and rate of ageing.
Through DNA insights, we create personalised nutrition and supplement plans aligned with your unique genetic code.
Gut Microbiome Analysis
Your gut is your body’s internal ecosystem. Our stool-based metagenomic testing evaluates bacterial diversity, digestive function, and immune balance.
Based on your results, our physicians create tailored dietary and probiotic protocols that support gut-brain and metabolic health.
Biological Age Assessment
Chronological age tells time, while biological age tells the truth. This test measures how your body is ageing at a cellular level through biomarker analysis of glycosylation patterns.
This helps provide a measurable longevity baseline to track rejuvenation and intervention results.
VO₂ Max & Metabolic Fitness Testing
A gold-standard indicator of cardiovascular efficiency, this test measures how effectively your body utilises oxygen during exertion.
Personalised training thresholds and exercise prescriptions to optimise endurance and heart health are analysed and designed based on your results.
Bone Density & Body Composition Scans
Using non-invasive ultrasound imaging, we assess skeletal strength, muscle mass, and visceral fat distribution.
This helps prevent osteopenia, osteoporosis, and muscle loss in a timely manner through targeted lifestyle and nutrition strategies.
