The Science Behind EVA
Standard lab ranges are designed to detect disease, not optimize health. A “normal” result can mask early dysfunction for years before symptoms appear. EVA uses longevity-optimized ranges stratified by age and sex, backed by peer-reviewed research from leading institutions in preventive medicine.
But we don't stop at better ranges. EVA translates every result into plain-language insight you can understand and act on — because a number only matters if you know what it means for your life.
Conventional Lab Range
Wide ranges designed to catch disease. You're either “normal” or flagged — no nuance in between.
EVA Precision Range
Five precision zones reveal where you actually stand. The same value shows room for improvement before it becomes a problem.
What we measure — and how deep you can go
165+ biomarkers available across all panels — 15 in your base panel, the rest available through quarterly specialty choices.

Included Biomarkers
Ranges built for YOU, not the average patient
Standard lab ranges use a single “normal” threshold for everyone. EVA's optimal ranges are stratified by age group and sex — because what's optimal for a 28-year-old woman is different from what's optimal for a 55-year-old man. Our reference dataset covers 24 age groups with sex-specific thresholds, so your interpretation is genuinely personalised.
How the same biomarker shifts with age — example: Vitamin D
Ages 25-30 (F)
Optimal: 40-60 ng/mLAges 45-55 (F)
Optimal: 45-65 ng/mLAges 65+ (M)
Optimal: 50-70 ng/mLWhy this matters: Your Vitamin D level changes as you age and changes differently based on sex. A 50 ng/mL result is excellent for a 28-year-old but suboptimal for a 65-year-old. EVA accounts for these differences automatically.
Beyond Individual Markers
EVA computes derived ratios and indices that reveal patterns invisible when looking at single biomarkers. These calculated metrics often provide deeper clinical insight than any individual value alone.
HOMA-IR
Homeostatic Model Assessment of Insulin Resistance
Formula
(Fasting Insulin × Fasting Glucose) / 405
Clinical Significance
Detects insulin resistance years before diabetes develops, enabling early intervention through lifestyle changes.
TG/HDL Ratio
Triglyceride to HDL Cholesterol Ratio
Formula
Triglycerides / HDL Cholesterol
Clinical Significance
A powerful predictor of cardiovascular risk and metabolic syndrome, often more accurate than LDL alone.
Omega-3 Index
EPA + DHA as Percentage of Total Fatty Acids
Formula
(EPA + DHA) / Total RBC Fatty Acids × 100
Clinical Significance
Measures cardiovascular protection from omega-3s. Target of 8-12% associated with lowest heart disease risk.
NLR
Neutrophil-to-Lymphocyte Ratio
Formula
Absolute Neutrophils / Absolute Lymphocytes
Clinical Significance
A systemic inflammation marker linked to chronic disease risk, immune function, and biological aging.
Calculated metrics are automatically computed from your results. Some are available from your base panel; others require a specialty panel. Your report will always show which metrics are available from your current test.
Five zones, not two
Traditional labs give you “normal” or “abnormal.” EVA gives you precision.
Critical Low
Requires immediate medical attention
This level poses an acute health risk and needs prompt intervention.
Below Optimal
Room to improve before it becomes a problem
You're not in crisis, but there's clear potential for improvement through lifestyle changes.
Optimal
Where you want to be for long-term health and vitality
This is the zone associated with longevity, disease prevention, and peak performance.
Above Optimal
Worth monitoring and adjusting
Not an emergency, but elevated enough to warrant attention and potential lifestyle tweaks.
Critical High
Requires immediate medical attention
This level poses an acute health risk and needs prompt intervention.

Key insight: Your result is compared against all five zones, not just flagged as “normal” or “abnormal.” This gives you granular insight into exactly what you need to optimize — and how much headroom you have before a problem develops.
