A generic check-up does not save lives, and the best evidence says so plainly: the most cited Cochrane review found that general health checks do not reduce mortality. What changes outcomes is a targeted assessment, matched to your age and risk, read the same day by a physician. Noria Health arranges a preventive work-up in Brussels within 48 hours, with results interpreted before you leave.
What stacking tests actually produces
The instinct is that more tests mean more safety. The measurements say the opposite, and they say it consistently.
| What was measured | The result |
|---|---|
| 14 screening tests over 3 years | 60.4% of men had at least one false positive, and 28.5% underwent an invasive diagnostic procedure because of it |
| Whole-body imaging in asymptomatic people, 68,436 participants | 32.1% critical or indeterminate incidental findings, against a confirmed cancer rate of 1.57% — roughly 20 findings to work up for one cancer found |
| Low-dose chest CT | 18.5% of the lung cancers detected were overdiagnosis: tumours that would never have caused symptoms |
| General health check, secondary endpoints | A 20% rise in new diagnoses per participant over 6 years, with no translation into survival |
Read the last line again. Six years of extra diagnoses, and nobody lived longer. That is the whole case against the long menu, and it is why a good clinic asks what you are at risk of before it asks what you want tested.
What does hold up
Only one screening test has demonstrated a reduction in all-cause mortality — low-dose chest CT, by 6.7% in the American trial. Not one other, including the ones everybody recommends. But several show a real, defined benefit in a defined population, and that qualifier is the point.
| Examination | In whom | The measured benefit |
|---|---|---|
| Screening colonoscopy | General invited population | Colorectal cancer incidence down 18% at 10 years; 455 people invited to prevent one cancer |
| Low-dose chest CT | Defined smoking history | All-cause mortality down 6.7% |
| Blood pressure | Every adult | Office measurement alone has a sensitivity of 0.54; home self-measurement rises to 0.84 |
Every demonstrated benefit is attached to a defined population. Outside that population the test loses its value and keeps its drawbacks.
Where the risk actually concentrates
A 2023 international analysis attributed about 57% of cardiovascular cases in women and 53% in men to five measurable factors: weight, blood pressure, cholesterol, smoking and diabetes. Five. Not fifty markers, not a whole-body scan.
Some conditions that matter stay silent for years — metabolism-related liver disease affects more than 30% of adults and usually produces no symptoms. That is an argument for looking in the right place, not for looking everywhere.
One caution worth carrying home: a coronary calcium score of zero is not a lifetime clearance. 53% of those concerned move to a positive score within 10 years, and the validity window is estimated at 3 to 7 years depending on profile.
What the assessment looks like
- A risk conversation before any test is ordered. Age, family history, what you already know. The panel is built from that, not from a brochure.
- One day, in one place. Bloods, imaging where indicated, cardiology where the risk profile calls for it, at an accredited private clinic in the Brussels area.
- Results read the same day, by a physician, in front of you. This is the step that most check-up packages skip, and it is the one that carries the value. A result you receive by email three weeks later is a document, not an assessment.
- A written report you can hand to your own doctor, with what was found, what was not looked for, and why.
Brussels is 1 h 50 from London by train and under two hours by air from Dublin, Amsterdam and most Gulf hubs.
What Noria Health does not do
- It does not employ doctors and does not practise medicine. The physician decides what is worth testing.
- It does not sell a fixed panel of tests. A panel that is the same for a 38-year-old and a 67-year-old is a product, not an assessment.
- It does not publish medical prices, and does not compare the prices of clinics or doctors — Article 37 of the Belgian Code of Medical Ethics prohibits it.
- It does not publish patient testimonials. Health data is a special category under Article 9 of the GDPR.
Questions people actually ask
Is a private health check-up worth it?
A generic one, on the current evidence, is not: general health checks do not reduce mortality, and stacking tests raises false positives without raising safety. A targeted assessment, matched to your risk profile and read by a physician, is a different proposition and rests on different evidence.
How long does it take?
One day at the clinic, with the appointment arranged within 48 hours of your request. The report follows the same day.
Should I ask for a whole-body scan?
In an asymptomatic person, the published series find 32.1% critical or indeterminate incidental findings against a confirmed cancer rate of 1.57%. That is roughly twenty things to investigate for one cancer found. There are situations where it is indicated; a routine check is not usually one of them.
Can I do this if I live outside Belgium?
Yes. Belgian private clinics take self-paying international patients, and no prior authorisation is needed when you pay privately.
What happens to my results afterwards?
They go to you, and to your own doctor if you ask for that. Noria coordinates the transfer securely; it does not interpret your results.
