What is a Biological Age Test?
A biological age test tries to estimate the "true age" of your cells. In other words: how old your body is biologically, regardless of your birth certificate.
The main types:
1. Epigenetic tests (DNA methylation): these read chemical tags on your DNA (methylation marks) at hundreds of sites across the genome. Well-known clocks: Horvath 2013, GrimAge, PhenoAge, DunedinPACE. 2. Biomarker-based tests: an algorithm that crunches blood test numbers. Example: Levine's PhenoAge. Cheaper, less precise. 3. Telomere length: once popular, now rated lower as an age marker. 4. Glycan-based tests (e.g. GlycanAge): measure sugar chains stuck to your antibodies.
How accurate are they? - Epigenetic clocks have the most science behind them. Newer ones (DunedinPACE, GrimAge 2) are tighter than early versions. - A result like "you're 5 years younger/older" carries a measurement wobble of roughly ±3–5 years. - Repeat measurements tell you more than a single snapshot.
For deeper scientific framing, see the [epigenetic tests guide](./epigenetic-tests).
Key Points
- •Epigenetic methylation clocks have the strongest validation
- •Biomarker algorithms are cheaper but less precise
- •Telomere length is rated lower these days
- •Measurement wobble of ±3–5 years means single results need caution
Does Insurance Pay?
Statutory insurance (GKV): No, generally not. Biological age tests are not listed in the GKV benefit catalogue. They count as IGeL services (individual health services you pay for yourself) and are fully out of pocket.
Why not? GKV only funds services that the Gemeinsamer Bundesausschuss (G-BA) has judged evidence-based enough and medically necessary. Biological age tests are not there yet. The science is interesting, but clinical usefulness (does the test actually change treatment or improve outcomes?) is not proven well enough.
Private insurance (PKV): it depends. Some PKV plans cover part of the cost if a physician orders the test. Before you test, get a quote from your PKV and ask for written confirmation of coverage.
Supplementary insurance: a few premium prevention plans bundle epigenetic age tests into their package. Not common, but a handful of providers do offer it.
Does GKV ever pay indirectly? Kind of. If you get covered medical checkups (a preventive blood panel), the resulting data can be fed into PhenoAge algorithms. The blood work is on GKV; the calculation is free online.
Key Points
- •GKV generally does NOT pay. Tests are IGeL services
- •Reason: clinical usefulness is not yet proven
- •PKV depends on your plan. Get written coverage confirmation
- •Indirect route: GKV-covered blood panel plus the free PhenoAge calculator
Providers and Costs (2026)
Epigenetic tests: - TruDiagnostic (USA): TruAge Complete incl. DunedinPACE. About $229 –469 (~€210–430). Blood sample. - MyDNAge (USA): about $229–349. - Elysium Index (USA): about $249, saliva. - Muhdo (UK): about €199–299, saliva. - Lifeline HealthEcho (Germany): from about €249–399. - Ganzimmun (Germany, via Heilpraktiker/physicians): €200–500. - Bioage Diagnostics, Hallmark Insights (DE/CH): €300–500.
Biomarker-based tests: - InsideTracker InnerAge 2.0: about $249. - German longevity private practices: in-house algorithms, often from €150 as part of a blood panel.
Telomere length: - TeloYears, TA Sciences: $89–150. Cheap, but rated lower scientifically.
GlycanAge: about €269.
What else adds to the bill: - Shipping and customs for US providers: €20–80 on top - Repeat measurement after 1–2 years doubles the cost, but gives you trend info - Physician interpretation as an add-on: €80–250 at longevity practices
Key Points
- •Epigenetic tests usually land at €200–500
- •TruDiagnostic with DunedinPACE is a well-documented scientific option
- •Biomarker tests are cheaper but less precise
- •Repeat measurements give you the most useful insight
Alternatives and Add-ons
If the price feels too steep, or you're sceptical about a single-provider number:
Free or very cheap baseline estimates: - PhenoAge online: plug in routine blood values from prevention checkups and get an estimate. Less precise than epigenetic clocks, but free. - Age-adjusted fitness tests: VO2 max, grip strength, sit-and-rise, flexibility - Rockport walk test: an indirect VO2 max estimate
Functional tests that often tell you more: - Sit-rise test: stand up from the floor without using your hands. A simple predictor linked to 6-year mortality. - VO2 max test (€100–250): for longevity, this is more telling than many markers - Grip strength (handheld dynamometer): cheap, and strongly linked to mortality - DEXA bone density (€50–150): a direct look at your muscle and bone mass
Smarter approach: instead of one pricey test, combine 3–4 angles: 1. Expanded blood values (PhenoAge) 2. Functional fitness (VO2 max, sit-rise, grip) 3. Body composition (DEXA or a good bioimpedance scale) 4. One epigenetic test every 2–3 years as a reference point
At €300–500/year, this gives you a sturdier picture than one expensive test on its own.
Key Points
- •The PhenoAge calculator with routine blood values is free
- •Functional tests (VO2 max, grip, sit-rise) often say more
- •Combine 3–4 angles instead of one expensive test
- •One epigenetic test every 2–3 years is plenty
Frequently Asked Questions
Does German insurance pay for biological age tests?
GKV generally does not. They're IGeL services. PKV may cover part of it depending on your plan. Get written coverage confirmation before you test.
Which test is best?
Scientifically strongest: newer-generation epigenetic tests (DunedinPACE, GrimAge 2, PhenoAge). TruDiagnostic TruAge Complete is a commonly recommended option. For a free baseline, use the PhenoAge calculator with routine blood values.
How often should I test?
Yearly is not useful. The measurement wobble (±3–5 years) is bigger than the change you'd expect in one year. Better: one baseline, then a repeat after 18–36 months to see how lifestyle changes move the needle.
What does the test actually do for me?
Realistically: **motivation and feedback**, not medical decisions. The test can show whether your lifestyle efforts are moving markers. It does not replace clinical diagnostics. Treat it as a self-monitoring tool.
Can a Heilpraktiker offer it more cheaply?
Some Heilpraktiker offer tests through partner labs (Ganzimmun and others) at lab prices plus a consultation fee. The price difference vs. going direct is usually small. What matters more is the quality of the interpretation.
Group testing in the community
Some chapters organise group orders for age tests at volume discounts, plus a joint session to go through results together.
