Live healthier for longer

We turn your bloodwork into a plan
and your next test into proof it worked


Interpretation is not the product

Most platforms explain your numbers, visualise your trends, generate insights. Then disappear.

Cato is built on a different belief:

Behaviour change is the product.

One Draw

60+ biomarkers across the seven systems that decide how you age: cardiovascular, metabolic, immune, hormonal, micronutrients, renal, stress. Nothing measured for curiosity. Every marker is one your protocol can move.

The Closed Loop

Healthcare is full of open loops. Tests happen, advice happens, life gets busy, nobody checks what happened next. Cato closes the loop: protocol, execution, retest. The cycle ends with evidence, not intentions.

Continuous Learning

A perfect protocol nobody follows is worthless. Cato learns what you actually sustain and adapts the plan to your real life, not an idealised one.

Clinical Oversight

Your protocol is supervised by a longevity specialist physician. They review your panel, approve what you act on, and track the shifts that matter.

Structured Intelligence

Every recommendation is weighed in the context of your full panel, conflicts are filtered out, and actions are ranked by what will move your biology most.

Others sell information Cato sells biological progress

HOW IT WORKS

From biomarkers to behavior.

STEP 01

Set your baseline

Tell us about your lifestyle and health status, and get your blood drawn at one of our partner labs.

STEP 02

Get your protocol

Cato identifies the handful of biological patterns that matter most and converts them into a structured 12-week action plan.

STEP 03

Execute and track

Weekly check-ins measure adherence. The system learns what you can realistically sustain. Every action is connected to a measurable objective.

STEP 04

Retest and improve

Re-draw your blood and see exactly what changed. Cato measures your progress, confirms which interventions actually worked, and makes your next protocol smarter.

NO TIERS. ONE STANDARD.

Cato isn't standard. It's only premium.

No basic plan, no upsell. Everyone deserves the full picture. Conventional care waits for disease to show up. We act years earlier, while the biology is still yours to change.

THE FOUNDATIONAL EIGHT

Advanced markers most panels skip.

Beyond routine markers, these eight biomarkers reveal metabolic health, cardiovascular risk, inflammation, nutrient status and biological ageing. They point to where small changes pay the biggest long-term dividends.

Cardio & Brain

Homocysteine

Linked to cardiovascular and neurological inflammation and cognitive decline. Lowering it through diet and supplements can reduce dementia risk.

Metabolic

Fasting Insulin

Catches early insulin resistance years before glucose markers ever look abnormal.

Cardiovascular

ApoB

Counts the cholesterol-carrying particles that actually drive atherosclerosis, a truer read on heart risk than cholesterol alone.

Genetic Risk

Lipoprotein(a)

An inherited cardiovascular risk factor lifestyle can't move. Knowing it lets us focus prevention where it counts most.

Inflammation

hs-CRP

Flags low-grade chronic inflammation that quietly damages blood vessels, the kind of risk that cholesterol can't show.

Hormone

Vitamin D

More than bone support. It acts as a hormone for immune function, inflammation, insulin sensitivity and mood.

Cardiometabolic

Uric Acid

A marker of cardiometabolic health, not just gout.

Stress

Cortisol

Your body's stress-response hormone, and a window into how much load you're carrying.

It's not enough for your results to be "okay."
Let's optimise for the best health now and for the future.

THE FULL PANEL WE TEST

Every system that matters

Immune & Inflammatory Health

Chronic, low-grade inflammation quietly drives most age-related disease. These markers surface it years before symptoms appear.

High Sensitivity C-reactive Protein Neutrophils HCT White cell count RDW Platelets Monocytes MCV Lymphocytes Eosinophils MCHC Red Blood Count Basophils Total Protein Globulin MPV MCH Haemoglobin

Metabolic Health

How efficiently your body processes glucose and fat is one of the strongest predictors of long-term disease risk and energy levels.

Uric Acid Insulin HDL % of total Triglycerides VLDL Total Cholesterol / HDL Ratio Creatine Kinase Total Bilirubin Gamma GT AST HbA1c ALT Alkaline Phosphatase HDL Cholesterol LDL

Nutrition & Micronutrient Status

Deficiencies in iron, B12, vitamin D and other essentials erode energy, mood and recovery long before standard panels catch them.

Magnesium Transferrin Saturation Ferritin Phosphate Calcium Transferrin Serum Iron Albumin Serum Folate Vitamin D Iron Binding Capacity Corrected Calcium Active B12

Hormonal & Thyroid Health

Hormones govern metabolism, sleep, mood and libido. Small imbalances compound into fatigue, weight change and reduced vitality.

Free Thyroxine (Free T4) Oestradiol Luteinising Hormone DHEA-S Free T3 Testosterone Sex Hormone Binding Globulin Free Androgen Index Thyroid Stimulating Hormone (TSH)

Renal & Electrolyte Health

Your kidneys filter everything a protocol changes. Tracking them and detecting early decline can help you implement lifestyle changes to prevent permanent, irreversible damage.

Estimated GFR Sodium Urea Chloride Potassium Creatinine

Cardiovascular Risk (Advanced Lipids)

Beyond standard cholesterol, particle-level lipid markers reveal cardiovascular risk that conventional panels miss entirely.

Apolipoprotein A1 Apolipoprotein B Apo B / Apo A1 Ratio Lipoprotein(a)

Stress & Neuroendocrine Load

Chronic stress reshapes biology at the hormonal level. These markers may expose the load before burnout or illness sets in.

Cortisol (7-9am) Homocysteine
