Biological age tests and German health insurance

A biological age test estimates how far your body has aged, as opposed to the age on your birth certificate. Different tests read different clues from your body, so their results are not interchangeable. Even one and the same test wobbles. On some older tests, two runs of the same blood sample can differ by years,^[9] so a single result is a rough reading rather than a verdict. The five main types work like this:

1. Epigenetic tests (DNA methylation) read chemical tags at hundreds of sites on your DNA. These methylation marks turn nearby genes up or down, more like a dimmer than an on/off switch. The formulas that turn the tags into an age are called clocks, and the best-known are Horvath,^[1] GrimAge,^[3] DNAm PhenoAge.^[2] and DunedinPACE^[5] Our epigenetic tests guide explains how they work.
2. Biomarker-based tests run ordinary blood values through an algorithm. The classic example is Levine's phenotypic age calculator, which uses nine blood markers.^[2]
3. Telomere length tests measure the protective caps on your chromosomes. They were once the hot marker and are rated lower as an age marker today.
4. Glycan-based tests such as GlycanAge measure sugar chains attached to your antibodies.
5. Proteomic tests estimate age from protein patterns, in blood or, in MOLEQLAR's case, cells from a cheek swab.^[23] They are newer and less validated than methylation clocks.

Of these names, PhenoAge causes the most confusion, because it stands for two different tests. Levine's nine-marker blood calculator came first, and it was later used as the training target for an epigenetic clock called DNAm PhenoAge.^[2] The blood version is cheaper (free online if you already have the lab values) and measures something different from the methylation test with the same name. It is not the weaker cousin, either: in Levine's original study, the blood-based score predicted disease and death better than the DNA methylation version.^[2] So if a provider just says PhenoAge, ask which one you are paying for: the free calculator's blood values or a methylation test at roughly €300 or more.

How precise is one result?

How precise a single result is depends mostly on the clock. Classic first-generation clocks such as Horvath and PhenoAge typically differ by about 1 to 2.5 years when the same blood sample is measured twice.^[9] In single cases, the gap reaches up to 9 years.^[9] GrimAge is far more stable, and newer versions of the clocks agree within about 1 to 1.5 years in most repeat runs.^[9] A single offset such as "you're 5 years younger" can therefore be partly lab noise. Before you order, ask the provider which clock version it uses and what its repeat-test error is.

That noise is one reason epigenetic clocks keep being rebuilt, even though they have the most research behind them of all five types. The newer ones improve on the first generation in different ways: GrimAge 2 predicts health outcomes better,^[4] while DunedinPACE gives more repeatable results.^[5] DunedinPACE also does not output an age at all. It reports a pace of aging, so 0.85 means 0.85 biological years per calendar year, and 1.0 is average.^[5] You judge it against that 1.0 and against your own change over time, not against your birth date. So the useful version of any of these tests is one you take more than once.

With statutory health insurance (GKV), you pay for a biological age test yourself, the first one and every repeat. These tests are not part of the GKV benefit catalogue, so doctors offer them as IGeL services (individuelle Gesundheitsleistungen), the self-pay extras on top of what insurance covers. You pay the full price, as with most self-pay longevity diagnostics, and no statutory insurer makes an exception for them.

That gap is not the result of a review that went badly. In outpatient care, GKV may only pay for a new test after the Gemeinsamer Bundesausschuss (G-BA) has recognised its benefit.^[19] The G-BA is the body that decides what statutory insurance covers, and no such assessment exists for biological age tests. The IGeL-Monitor, which rates self-pay services for patients, has not rated epigenetic or biological age tests either (checked October 2026).^[8] The clinical case for one would be thin, too. As of October 2026, we know of no randomised trial showing that knowing your biological age improves health beyond standard checks of cholesterol, blood sugar and blood pressure.

Those standard checks are exactly what GKV does pay for in its Gesundheits-Check-up, and the contents show why it cannot stand in for a biological age test. From age 35 you get it free every three years.^[12] It covers a medical history, a physical exam, blood pressure, blood fats, fasting glucose, a urine test and advice.^[12] A one-time test for hepatitis B and C comes on top. Between 18 and 34 you get the check-up only once and without the urine test.^[12] Blood is then taken only if you have a risk profile, such as a family history, overweight or high blood pressure. None of these versions includes a biological age, epigenetic markers or DunedinPACE.

The check-up's blood values can still supply some inputs for a lab-based biological age, but they get you less far than the longevity internet suggests. Levine's phenotypic-age calculator needs nine blood markers,^[2]:

• albumin
• creatinine
• fasting glucose
• C-reactive protein (CRP, an inflammation marker)
• lymphocyte percentage
• mean corpuscular volume (MCV, the average size of your red blood cells)
• red cell distribution width (RDW, how much that size varies)
• alkaline phosphatase
• white blood cell count

The check-up delivers only fasting glucose^[12] so eight of the nine markers are missing. Your Hausarzt (family doctor) can add them on GKV only when each value is medically needed. That covers checking a suspected anaemia, inflammation or kidney problem, or monitoring a known condition or medication. Curiosity is not a medical reason, so otherwise you pay for the missing labs as an IGeL service. Expect about €30 to 80 on top of the free check-up (indicative, check with your practice).

Bonus programmes from AOK, TK, Barmer or DAK do not change that picture. They reward gym membership, dental check-ups or vaccinations with points or cash, usually €30 to 200 a year (indicative), and none of them covers a biological age test. You can sometimes spend the bonus on a self-paid test, but that is cashback for prevention rather than coverage. It might cover your share of a dental cleaning, not a TruDiagnostic kit. TK's free TK-Coach app includes lifestyle self-tests, so TK members can check there whether it offers a biological-age questionnaire. That would give a lifestyle estimate, not a lab value.

Private insurance (PKV) pays only rarely and case by case, because a test in a healthy person is seldom medically necessary under the policy.^[6] The bill itself is not the hurdle. The fee schedule for private patients (GOÄ) has no item of its own for a biological age test. A doctor can still bill it under fitting lab items, or as an analogous service that names a comparable GOÄ item.^[16] The hard part is getting the money back. Private insurance pays for medically necessary treatment of illness or accident and for screening in statutory programmes.^[6] Beyond that, it pays only for what your policy terms explicitly include (§ 192 VVG, the Insurance Contract Act).^[6] A longevity test in a healthy person is usually neither treatment nor statutory screening, so your case rests on your physician's documented reason and on your policy terms.

A few premium add-on plans for prevention do bundle an epigenetic age test into their package. It is not common, but if you already have such a plan, its benefit list is worth a look before you pay for a test yourself.

Applying to your PKV for coverage

If you have PKV and want to try, the order matters:

1. Have a physician order the test and write down the actual clinical reason, for example a family history of early heart disease or a metabolic condition, if there is one. The diagnosis code has to describe that real reason. A code alone does not create medical necessity, and a code chosen just to get a refund is a misstatement to your insurer.
2. Send a written Kostenübernahme-Antrag (cost-coverage application) before you order the test. A claim after testing is much harder to push through.
3. Ask about premium outpatient plans. Full-cover plans (Volltarife) with a broad outpatient catalogue sometimes cover advanced diagnostics case by case, and so do some top-up plans for civil servants on Beihilfe (state aid towards their medical costs). Brochures rarely spell this out, so ask an independent insurance broker (Versicherungsmakler) about the premium tier at your insurer, and expect no guarantee.
4. Object to a denial in writing. A written objection is worth trying, ideally with a second written statement from your physician on why the test is needed. How often this works varies by insurer and policy.

Whichever route you take, you usually pay the provider first, which makes the price differences between providers the part you can actually control.

Most epigenetic biological age tests sold to people in Germany cost €200 to 500, and all of them are self-pay. The cheapest kit in the table below starts at €129.90 (MOLEQLAR's cheek-swab test),^[23] while premium bundles cost more, around $850 plus import VAT.^[20] Orders from US providers can attract German import VAT of 19% on the declared value, which the carrier or provider tells you at checkout. Check first, though, that the provider ships to Germany at all.

The table lists German providers first. Prices marked "Oct 2026" were checked on the provider's own page in October 2026; the others are indicative, so check them before you order.

Sources: provider pages [20–25]; other prices from earlier listings. The cheapest route is missing from the table because it is not a product. Levine's PhenoAge calculator^[2] is free, but it needs blood values that usually cost about €30 to 80 as self-pay labs (indicative).

The kit price is rarely the whole bill, either. US orders add shipping and customs handling, often €20 to 80 (indicative). A repeat test doubles the cost, but it is the only way to see a trend. A physician's interpretation at a longevity practice adds about €80 to 250 (indicative). With a repeat test and a doctor's interpretation, an epigenetic test easily ends up costing twice its list price.

What the table cannot show

Price is only one column, and behind several of the rows sits a detail that changes whether the test suits you:

• TruDiagnostic (USA): the TruAge Test reports OMICmAge (a biological age), SYMPHONYAge (ages for 11 organ systems), DunedinPACE, a telomere estimate and inflammation and immune scores from a finger-prick blood sample^[20] A bundle with the TruHealth panel costs $849, and the shop does not list GrimAge or Horvath.^[20] Check at checkout that it ships to your address in Germany.
• InsideTracker (USA): InnerAge 2.0 costs $249 with a blood draw at a partner lab, or $119 more for a mobile draw (as of October 2026),^[21] and existing Ultimate Plan customers can add it for $99.^[21] The draws are only offered in the US and Canada, so from Germany you can only upload results from your own doctor through a membership.^[22]
• Cerascreen (Germany): the €499 list price is also what the test costs with a longevity consultation. The cheek-swab algorithm was co-developed with the Fraunhofer IME,^[24] and the kit has been out of stock at times, so check cerascreen.de before you plan around it.
• Elysium Index (USA): a saliva test that reports a biological age, a cumulative pace of aging and nine organ-system ages.^[25]
• MOLEQLAR (Germany): the epi-proteomics test uses a cheek swab, and the €129.90 price is for the Essentials kit plus shipping.^[23] Proteomic tests are less validated than methylation clocks, so ask which published model it uses. Because MOLEQLAR also sells supplements, the FAQ checks on spotting a reputable test apply here too.
• GlycanAge (UK): prices vary by market and subscription tier, and partner sites have listed anything from about €299 to €499 for a single test, so confirm the current price on glycanage.com.
• Ganzimmun (Germany): sold through physicians and Heilpraktiker, with a price that depends on the panel, so ask the practice for its current price list (Leistungsverzeichnis).
• German longevity practices often run their own blood-marker algorithms, from about €150 as part of a blood panel (indicative).
• Telomere tests: standalone consumer kits are getting hard to find, since TeloYears (once about $89) has scaled back its consumer offer and TA Sciences points consumers to its physician partners (not re-checked). If you do find one, keep in mind that telomere length is rated lower than methylation clocks for estimating biological age and predicting mortality.

Several of these providers sit in the US, and that matters for your data as much as for the price. Your methylation results are sensitive data under GDPR Art. 9,^[7] and a direct-to-consumer provider will normally process them on the basis of your explicit consent. Before you order from a US provider such as TruDiagnostic or Elysium, check whether it is certified under the EU-US Data Privacy Framework (dataprivacyframework.gov).^[14] If it is not, ask which safeguard it uses instead, such as Standard Contractual Clauses (EU-approved contract terms). The framework has been challenged in court and could change, as its two predecessors did. So also ask how long the company keeps your sample and data, how you can have both deleted, and what happens to them if the company is sold.

Instead of one €500 kit, you can combine three or four cheaper ways to check how you are ageing for about €300 to 500 a year (indicative). In our view, they give a sturdier picture than one expensive snapshot. We would start with the blood values the free PhenoAge calculator needs, a few fitness tests and a body composition measurement. If you want a number on top, one epigenetic test every two to three years makes a good reference point.

Free and low-cost checks

Most of these checks take minutes, and several cost nothing. Prices here are indicative, so check them before you book.

• Our free pace-of-aging test takes two minutes without signup and gives a lifestyle-based estimate, not a lab value.
• Levine's PhenoAge calculator (the blood version) is free,^[2] but it needs nine blood markers. Check-up 35 covers only fasting glucose,^[12] so budget about €30 to 80 for the other eight, which your Hausarzt can add as a self-pay extra.
• The sit-rise test asks you to stand up from the floor without using your hands. In 2,002 adults aged 51 to 80, lower scores were linked to higher all-cause mortality over about six years.^[11] Skip it, or have someone next to you, if you have knee, hip or balance problems or osteoporosis.
• Grip strength takes a few seconds on a handheld dynamometer and is cheap to measure; our grip strength tool is a place to start.
• The Rockport walk test is a walking test that estimates VO2 max indirectly, without a lab.
• A VO2 max test (spiroergometry, about €100 to 280) measures in a lab how much oxygen your body can use at full effort. If you have heart disease or several risk factors, clear a maximal exercise test with your doctor first.
• A DEXA bone density scan (€50 to 150) measures bone density. A separate whole-body DEXA scan also estimates muscle and fat mass, so ask for that scan specifically if body composition is what you want (see our DEXA guide). A good bioimpedance scale is the cheaper home option.

Worked example: a 38-year-old in Munich or Berlin

Take a 38-year-old in Munich or Berlin with statutory insurance (GKV) and €400 to 500 to spend. This example puts the money into blood markers and day-to-day recovery tracking rather than the fitness and body-composition tests above, which you can swap in instead. In the first year, it could look like this (all prices indicative, so check them before you book):

• The GKV Gesundheits-Check-up (free from 35, every three years) gives you a lipid panel, fasting glucose, blood pressure and a urine test.^[12] Ask your Hausarzt to add albumin, creatinine, a full blood count (white cells, lymphocyte %, MCV, RDW) and alkaline phosphatase as a self-pay add-on for roughly €30 to 80. With the hsCRP from the panel below, that completes the nine PhenoAge markers.
• An IGeL longevity panel, for example via Ganzimmun or a comparable specialist lab, costs about €250 to 350 depending on scope. It adds markers the check-up leaves out: ApoB and Lp(a), two measures of the particles that carry cholesterol, hsCRP (a sensitive inflammation marker), HbA1c (your long-term average blood sugar), fasting insulin, a hormone panel and ferritin, which reflects your iron stores.
• A Polar H10 chest strap (about €90, one-off) gives reliable heart rate data and heart rate variability (HRV), the small variation in time between heartbeats.
• The HRV4Training app (about €10, one-off) takes morning HRV readings that track how well you recover.

The first year totals about €380 to 530, including the lab top-up that makes the PhenoAge calculator work. Later years drop to about €250 to 350 for the panel alone, or less if you skip a year. In Austria and Switzerland, the GKV Check-up 35 and IGeL rules do not apply, so ask your own insurer what its prevention check includes.

How to read your result

There are no validated cut-offs that turn a biological-age result into a medical decision. A result close to your age is not a clean bill of health, and a high one is not a diagnosis, because these tests are wellness information. So do not start, stop or change medication, hormones or supplements because of a result. Chest pain, breathlessness, palpitations or other symptoms need a doctor, whatever the test says.

Read a DunedinPACE result against the average pace of 1.0 and against your own trend.^[5] If any result looks high, retest with the same provider and the same clock before you read much into it. On classic clocks, two runs of one and the same sample can already differ by years.^[9] A result that stays high on repeat tests is a good reason to see your doctor about the standard risk factors: blood pressure, blood lipids, blood sugar, smoking and family history. The extra markers from a longevity panel, such as ApoB, Lp(a), hsCRP, HbA1c and fasting insulin, are worth discussing at that appointment.

Whether you then need further tests such as a coronary calcium score depends on that overall risk, not on the clock result alone. A calcium score is a CT scan, so it uses X-rays,^[17] and as a self-pay service it costs about €150 to 300 (indicative). Decide on it with your doctor, based on your risk factors. Whatever the number says, the levers stay the same: sleep, exercise, diet, alcohol and not smoking.

Statutory insurance does pay for a different heart scan, but only with a medical reason. CCTA (CT coronary angiography) is a CT scan of the heart arteries with contrast dye, and since 1 January 2025 practices can bill it to GKV.^[18] It is covered when chronic coronary heart disease is suspected, or to rule out coronary disease before a planned heart operation.^[17] It is not a screening test for people without suspected heart disease, and the FAQ below lists the exact conditions.

How often to retest

For classic clocks that output an age, a retest every two to three years is a sensible rhythm. Repeat runs of one sample can differ by years on clocks like Horvath and PhenoAge.^[9] On a yearly rhythm, that lab noise can easily hide a real change. DunedinPACE gives very repeatable results,^[5] but repeatability is only half of what a retest needs: the clock also has to react when you change something. A later analysis of the CALERIE trial, which tested calorie restriction in healthy adults, looked at exactly that.^[10] Two years of calorie restriction slowed DunedinPACE compared with the control group.^[10] The methylation versions of PhenoAge and GrimAge, by contrast, showed no clear effect, and all of the effects were small.^[10] So if you are actively changing something, a DunedinPACE retest after about 12 months is reasonable. These intervals are a practical rule of thumb rather than a tested recommendation, so small shifts still deserve caution.
