Diagnostics

120 markers, seven systems, one morning.

What each test runs on, how long it takes, and what it can and cannot tell you about the next thirty years.

The number, broken down

120

markers, measured across seven systems. Each block below shows what sits behind its number.

System 01

Cardiovascular

22

markers

What it tells you

How many atherogenic particles you carry, whether plaque has started in your carotid arteries, and how your heart conducts and recovers.

What it does not

It does not predict a single event, and it does not replace a coronary calcium scan when your family history calls for one.

Instruments

Carotid ultrasound with intima-media thickness, 12-lead resting ECG, 24 h ambulatory blood pressure, ApoB, Lp(a) and a full lipid panel from the 07:30 draw.

Duration

Same day: the ECG at 07:30, then 20 min of ultrasound after your DEXA at 08:00. The blood pressure cuff goes home with you for 24 h.

ApoB

Watch

0.92

g/L

0.40

1.40

Target

Below 0.80 g/L

Venous sample at 07:30, fasted 10 h. The lab flags only above 1.30 g/L; our target is stricter.

System 02

Metabolic

24

markers

What it tells you

How your glucose moves through real days and real meals, and how hard your pancreas works to hold it there.

What it does not

An HbA1c averages three months and hides the spikes, so it is never read on its own.

Instruments

Dexcom G7 continuous glucose monitor for 14 days, HbA1c, fasting glucose and insulin, HOMA-IR, liver enzymes, triglycerides and uric acid.

Duration

10 min to fit the sensor, same day. You wear it at home for 14 days and the curve joins your report on day 15.

Fasting insulin

Out of range

14.2

µIU/mL

0

25

Target

2 to 8 µIU/mL

Same 07:30 draw. Read with fasting glucose as HOMA-IR, here 3.4.

System 03

Hormonal

18

markers

What it tells you

Thyroid output, sex hormones, growth signalling and the stress axis, read against your age and, where it applies, your cycle.

What it does not

One morning sample is a snapshot. Cortisol and oestradiol move by the hour, so nothing is adjusted on a single draw.

Instruments

Morning serum panel (TSH, free T4, free T3, total and free testosterone, oestradiol, SHBG, DHEA-S, IGF-1) and a four-point salivary cortisol kit.

Duration

Part of the 07:30 draw, same day. The saliva kit is done at home over one day and returned by post within 3 days.

TSH

Optimal

1.8

mIU/L

0

5.0

Target

0.5 to 2.5 mIU/L

Drawn at 07:30 every year, so each value is compared at the same hour.

hs-CRP

Watch

1.6

mg/L

0

5.0

Target

Below 1.0 mg/L

No infection and no hard session in the 7 days before the draw. Repeat booked for week six.

System 04

Inflammatory and immune

16

markers

What it tells you

Whether a low, silent inflammation is running in the background, and how your white cells are balanced.

What it does not

hs-CRP rises after a cold or a hard training week. A raised value is repeated at six weeks before it means anything.

Instruments

hs-CRP, IL-6, ferritin, homocysteine and a full blood count with differential and neutrophil to lymphocyte ratio, all from the 07:30 draw.

Duration

No extra time, same day. Results are back within 48 h.

System 05

Body composition

14

markers

What it tells you

Where your fat sits, how much muscle you carry on each limb, and the mineral density of your hips and spine.

What it does not

It does not tell you how that muscle performs. Strength is measured in the fitness block, on the same morning.

Instruments

DEXA whole-body scan on a Hologic Horizon A: visceral adipose tissue, appendicular lean mass index, bone mineral density at hip and lumbar spine.

Duration

11 min on the table at 08:00, same day, fasted. The dose is lower than a day of natural background radiation.

Visceral fat

Out of range

1.32

kg

0

2.50

Target

Below 1.00 kg

VO2 max

Optimal

46

mL/kg/min

25

65

Target

Above 42 for your age and sex

Ramp protocol to exhaustion, measured breath by breath. Retested every 6 months.

System 06

Cardiorespiratory and musculoskeletal fitness

14

markers

What it tells you

The ceiling of your aerobic engine, where your two thresholds sit, and the strength and balance that keep you independent at 80.

What it does not

A high VO2 max does not clear your arteries. It is read next to the cardiovascular block, never instead of it.

Instruments

VO2 max on a metabolic cart (Cosmed Quark CPET) on a cycle ergometer, lactate thresholds, Jamar grip dynamometer, isometric mid-thigh pull and single-leg balance on a force plate.

Duration

50 min, same day, after the light breakfast we serve once your bloods are drawn.

System 07

Sleep and autonomic recovery

12

markers

What it tells you

How long and how deeply you actually sleep at home, and how fast your nervous system recovers overnight.

What it does not

It is not a diagnostic sleep study. If the screen suggests apnoea, we refer you for full polysomnography.

Instruments

Oura Ring Gen 4 for 7 nights with overnight HRV and resting heart rate, plus one night of WatchPAT One home apnoea screening.

Duration

A separate stretch at home, starting the night after your morning: 7 nights. The devices go back by courier.

Overnight HRV

Optimal

52

ms

100

Target

45 to 80 ms (RMSSD)

Median of 7 nights, taken during the deepest sleep phase.

Arrive fasted at 07:30. Leave before lunch with every same-day test done and a physician who has already read them.

Physician readout

Your physician walks through every same-day result and agrees the three things to work on first. Glucose and sleep data follow on day 15.

Boundaries

What we do not measure.

Three tests we are asked for every week, and why the answer is no.

01

Genetic risk scores sold as destiny

A polygenic score moves a probability by a few points. We never sell it as a forecast, and it never outweighs your ApoB or your blood pressure.

02

Unvalidated microbiome panels

Results change from one stool sample to the next, and two labs can read the same sample differently. Until a panel predicts an outcome, it stays out of the report.

03

Full-body MRI screening without a reason

Whole-body scans flag incidental findings in many healthy people, and each one leads to more scans. We image an organ when a result points to it.

Every test in the baseline has to change a decision. If it cannot, it costs you money and worry, so we leave it out.

The lab and the people

Where it happens.

One accredited lab, two physicians and a clear rule for what happens to your samples.

The lab

Bloods run in Madrid, within four hours

Samples travel by cold courier to our partner reference laboratory in Tres Cantos, 25 minutes from the clinic, and are run on Roche cobas analysers the same day.

ENAC accredited

ISO 9001

Your samples

Kept 30 days, then destroyed

Blood and saliva stay at the lab for 30 days in case a marker needs a rerun, then they are destroyed. Nothing is stored, sold or used for research without a separate signature.

Your baseline

Start with a number, not a feeling.

One morning in Madrid. A report you keep. A physician who reads it with you.
