The check-up at 35 covers more than most people think. If you live in Switzerland, your basic insurance covers a lot less of it. What statutory prevention actually does, where a single blood value tells you less than you’d expect, and where imaging fits in, not as a must.
At 35, you get a letter from your health insurer in Germany reminding you of something you haven’t booked yet: your check-up. Most people let the appointment slide, or turn up without really knowing what’s being tested. In Switzerland the question looks different, because that appointment doesn’t exist in that form at all. Both gaps, the missed German appointment and the missing Swiss equivalent, point to the same question: what do you actually know about your own body if you’re relying only on what’s covered for free?
What the check-up at 35 actually covers, and what it doesn’t
The statutory health check-up is a benefit of Germany’s statutory health insurance. Adults can use it once between 18 and 34, then every three years from 35. It includes a conversation about your history, a physical exam, a blood pressure check and a review of your vaccination status. From 35, a urine sample plus your blood glucose and cholesterol values are added, with a one-off option for a hepatitis B and C test.
What it isn’t: a full picture of your metabolism, your hormones or your nutrient status. The check-up is built around the three conditions that justify it legally, namely cardiovascular disease, kidney disease and diabetes. Everything outside that, thyroid, iron, vitamin D, stays out unless there’s a specific medical reason to look.
Alongside the general check-up, there’s a whole separate set of statutory screening programmes, each tied to a specific age or sex, covering things like skin, breast, bowel, prostate, the abdominal aorta or, since April 2026, lungs for heavy smokers and ex-smokers. These programmes are purely informational here, not a product of ours, and Germany runs considerably more of them than Swiss basic insurance covers automatically:
| Examination | Germany (statutory insurance) | Switzerland (basic insurance) |
|---|---|---|
| Cervix (women) | From 20, annually; from 35, combined test every three years | Smear as part of a gynaecological check-up, every three years |
| Breast (women) | Clinical exam from 30, annually; mammography 50 to 75, every two years | Only automatically covered at elevated risk, otherwise varies by canton |
| Skin | From 35, every two years | Only at elevated risk or clear suspicion |
| Bowel | From 50, stool test or colonoscopy | 50 to 69, stool test every two years or colonoscopy every ten years |
| Prostate and external genitalia (men) | From 45, annually | Not routinely covered, decided case by case with your doctor |
| Lungs (heavy smokers/ex-smokers) | Since April 2026, 50 to 75 | No comparable programme known |
| Abdominal aorta (men) | From 65, one-off ultrasound | No comparable programme known |
In Switzerland, the general check-up works differently. Mandatory basic insurance doesn’t cover a general health check for people without symptoms, that’s explicitly not a required benefit. What it does cover, as in the table above, are individual, age- and sex-specific programmes. A general blood check with cholesterol or glucose isn’t automatically included unless there’s a medical reason for it.
If you take up your check-up and the matching screening programmes in Germany, you get a solid baseline. If you live in Switzerland, you only get one if you organise it yourself.
Why one value tells you less than a trend
Even if you take up your check-up regularly, you end up looking at a number and a range: your cholesterol came in at a certain value, the reference range runs from a lower to an upper limit. That range describes a whole population, not you specifically. It’s deliberately wide, so it holds true for as many healthy people as possible.
Lab medicine has a concept for this that’s far less well known than the reference range itself: the reference change value, the difference between two results from the same person that goes beyond the normal noise of measurement and day-to-day variation. Two values can both sit comfortably inside the population range and still show a shift that matters for you personally, once you put them side by side instead of looking at either alone.
That’s why a value measured repeatedly tells you more than the same value measured once. Not because the single reading is wrong, but because it’s only half the information.
One value versus a trend
Three measurements from the same person over three years, all within the population reference range.
Short
A single blood value tells you where you stand today. Only a trend tells you whether something is actually changing for you, even within the normal range.
Where imaging fits in, and where it doesn’t
Your check-up and your blood values answer questions about metabolism and organ function. They don’t show you what an organ looks like structurally, that takes imaging, for example a whole-body MRI. One doesn’t replace the other: blood values and imaging answer different questions, and they’re not two stages of the same test.
What a whole-body MRI shows, where its limits lie, what incidental findings it tends to turn up, and who it’s actually a sensible addition for, we cover in detail in a separate article, because the topic is too important for a side note here.
For everyday prevention, that suggests a simple order: start with what’s statutorily covered or easy to repeat, then add something targeted later if you want to. Imaging is an option at the end of that order, not a shortcut at the start of it.
Who this actually makes sense for
The statutory check-up is plenty as a baseline for many people with no family history and no symptoms, especially if they actually take it up.
A repeated, self-funded blood test makes additional sense if you live in Switzerland and don’t get a comparable appointment through basic insurance, if you want to compare values over several years rather than get a single snapshot, or if you want to cover ground the statutory check-up doesn’t, such as thyroid or iron status. That’s why we offer our own broad blood test, Holistic Health, at Aeon, which you can book on its own, independent of a scan: CHF 450 in Switzerland, €319 in Germany.
It makes less sense if you have acute symptoms, in which case seeing a doctor is the right move, not a self-pay test. And imaging generally only makes sense once your blood values and history raise a specific question that blood alone can’t answer, or if you want a structural picture out of your own interest and understand the limits we set out in the MRI article.
Key takeaways
The short version
Prevention isn’t a single appointment, it’s a habit. The statutory check-up is a good start where it exists. What it doesn’t cover, you can add yourself, ideally in a way that lets you compare the same value over time.
Frequently asked questions
What exactly does the statutory check-up at 35 cover?
It includes a conversation about your history, a physical exam, a blood pressure check and a review of your vaccination status. From 35, urine, blood glucose and cholesterol values are added, plus a one-off optional hepatitis B/C test. It’s specifically aimed at cardiovascular disease, kidney disease and diabetes.
Do I get a free health check in Switzerland too?
Not in the form it takes in Germany. Mandatory basic insurance doesn’t cover a general check-up for people without symptoms. It only covers individual, age- and sex-specific programmes, such as gynaecological screening or bowel cancer screening from 50.
Is a single blood test enough to interpret my values?
A single value shows you where you stand against the population. Whether something is changing for you personally only shows up once you compare several measurements, because the general reference range is built for a whole population, not just you.
Is a whole-body MRI an alternative to a blood test?
No, it answers a different question. A blood test shows metabolic and organ function, an MRI shows structure. They complement each other where that’s useful, neither is a step toward the other.
How often should I repeat my blood work if I don’t have symptoms?
It depends on the specific marker and your own starting point. As rough guidance, many people repeat a broad blood test once a year, it’s worth discussing the details with a doctor.
