TruDiagnostic TruAge, Elysium Index, TallyAge and GlycanAge compared on price, sample, what they measure and what the research says about reliability.
Researched from published studies and manufacturer specifications, checked .
We have not tested products ourselves. How we researchTruAge ($499, finger-prick blood, methylation clocks incl. DunedinPACE) is the broadest; Elysium Index ($299) and TallyAge ($249) are cheaper saliva or cheek-swab methylation tests; GlycanAge (from EUR 499) measures immune glycans instead. Clocks can differ by up to 9 years between replicates, and no test is shown to improve health outcomes.

The short answer: if you want the broadest report, TruDiagnostic’s TruAge is $499; if you want a cheaper methylation test, Elysium Index is $299 and Tally Health’s TallyAge kit is $249; GlycanAge, from EUR 499, measures immune-system glycans instead of DNA methylation. None is proven to improve health, none diagnoses disease, and the clocks behind them can be noisy: a 2022 study found technical noise moved results by up to 9 years between replicates of six prominent clocks. Prices are from each brand’s storefront on 29 Sept 2026.

Sources: TruDiagnostic storefront and site; Elysium Index; Tally Health, where the kit’s product page and storefront data both show $249 ($234 with a membership); a $229 figure seen in a search listing could not be found on Tally’s site and is not used. GlycanAge’s FAQ gives the list price in euros (approx. EUR 499 single, EUR 849 for two tests) and says US pricing commonly runs USD 499 to 549 and USD 849 to 899, varying by provider; its home page and shop showed no price to our reader, so check the price at checkout.
We found no study that ran these four commercial products on the same people, so nobody can say which is more accurate.
Consider it as a curiosity or a rough trend line, not a health check. A gap between biological and chronological age is not a diagnosis, and a single result cannot tell you which habit to change; the biomarkers that clinicians act on (blood pressure, ApoB, glucose) and fitness measures such as VO2 max have firmer links to outcomes. If you retest, use the same company and sample type, and expect noise. How one widely publicised longevity protocol uses these tests is covered in this explainer. Talk to your doctor about any result that worries you.

They are noisy at the individual level. A 2022 Nature Aging paper found technical noise produced deviations of up to 9 years between replicates of the same sample for six prominent epigenetic clocks, and a computational fix brought most replicates within 1.5 years. Consumer tests may or may not use that fix; we could not confirm which do.
It depends on what you want measured. DunedinPACE (in TruAge) has published test-retest, mortality and trial-response data; GlycanAge measures a different signal (immune IgG glycans). No head-to-head study of the consumer products exists, so we do not rank them on accuracy.
Not reliably for one person. In the CALERIE trial (220 adults, 25% calorie restriction for two years) DunedinPACE showed slower ageing while two other clocks did not, with small effect sizes, so results depend on the clock, and group averages are not personal answers.
