Compare six biological age test options by sample type, markers, limits, and cost. Learn what results can and can't tell you.
A biological age score can look precise while telling only one part of your health story. Some tests look at DNA marks or immune proteins; others measure blood markers across body systems. Here are six options, starting with Vitals Vault, and what each can help you understand.
A broad blood panel gives you more than an age score. Vitals Vault is a clinician-authorized lab testing service for people who want to review health markers across body systems and keep a record over time.
Its one-time panels start at $99 and cover 120 to 160+ biomarkers, depending on the panel, with testing at Quest. That breadth can help you look at metabolic health, heart-related markers, hormones, liver function, kidney function, inflammation, nutrients, and longevity markers in one lab snapshot.
That is a different job from an epigenetic clock. A blood panel measures current markers that can inform a discussion about health risks; it doesn't read every aging process in your cells. Vitals Vault also provides educational, AI-assisted insights and a place to organize past lab reports. Those tools can help you spot a trend or prepare a question for your clinician, but they don't diagnose disease.
If you want a first look at a biological age estimate, Vitals Vault also has a free blood-marker biological age calculator. A calculated age is still an estimate, not a lifespan forecast.
People often focus on the single number. A more useful question is which markers shaped it, and whether those markers fit the rest of your health picture. Vitals Vault is a reasonable starting point if you want broad blood data rather than a test built around one molecular clock.
SystemAge looks across systems instead of giving you only one whole-body age. It is a blood-draw test that covers 19 physiological systems, making it relevant if you want an organ-level view of how different parts of the body may compare.
Its 19-system scope is the main reason to consider it; the trade-off is that a broad report may take more work to interpret than a single score. The exact markers behind each system score aren't spelled out up front, so ask what the report includes before treating any one result as a complete organ assessment.
It's also worth separating organ-level estimates from direct function tests. A system score can't replace a clinician's evaluation or tests ordered to investigate a symptom. And a high or low age estimate alone doesn't tell you what caused it. Use the report to frame questions, not to choose a treatment by yourself.
For a multi-marker blood snapshot that includes longevity-related testing, Vitals Vault's longevity and healthy-aging markers may be a more straightforward route. The right choice depends on whether you want an organ-system aging report or a broader set of familiar lab measures.
GlycanAge measures a feature of immune proteins, notDNA methylation. The blood test analyzes patterns of sugar molecules attached to immunoglobulin G, or IgG. IgG is an antibody, and the attached sugar structures can affect how it behaves in immune and inflammatory processes.
These patterns are called glycans. They shift with age and health, but they don't act like a simple inflammation score or a diagnosis. GlycanAge measures inflammation-related aging by analyzing sugar molecule patterns on IgG.
GlycanAge may suit someone who is specifically interested in immune-related aging and wants a marker distinct from an epigenetic clock. Consider whether this specific immune-protein measure answers a question you already have.
A glycan result doesn't tell you that inflammation is the cause of a symptom, nor does it name a treatment. It is one measurement within a complex system. If your result concerns you, bring it to a clinician who can review it alongside symptoms, medical history, and standard tests.
It's tempting to view a younger glycan age as proof that a habit worked. One result can't establish that. If you want to track change, keep testing conditions consistent and allow enough time for a meaningful trend. The test's specialized focus is its strength, but it is not a substitute for a wider health review.
myDNAge uses Horvath's original epigenetic clock. It is available with a blood or urine sample, at $299 for each test. This option may interest readers who want a named, established clock rather than an age score based on a broad panel of routine blood markers.
Epigenetic clocks estimate age from patterns of DNA methylation, chemical marks that help regulate how genes work without changing the DNA sequence itself. The clock model looks for age-linked patterns across DNA sites. A clock result is an estimate, not a full account of aging or a prediction of individual disease risk.
The original Horvath clock is one of the most cited in academic literature. That academic use is a point of interest, but it doesn't mean every consumer result predicts a person's lifespan or response to a supplement. Clock models can give different results because they use different inputs and were built for different aims.
One important distinction: estimating chronological age from methylation is not the same as measuring how fast someone is aging or predicting a specific health outcome. If your score is older than your calendar age, treat it as a prompt to ask what the test can and cannot show. It does not identify a cause on its own.
If you choose this test, make a note of your collection date and any major changes to your routine. That context can matter when you compare a later result. Vitals Vault's biological age biomarker page explains a separate retesting approach for tracking blood-based estimates over time.
AgeRate analyzes more than 50,000 epigenetic markers in blood. It uses DNA methylation technology to estimate biological age. Its scale may appeal to people interested in molecular aging data, while its connected app is designed to encourage habit improvement around the result.
A high marker count isn't a guarantee of better accuracy or clearer advice. The key questions are what the clock was built to predict, how well it has been tested, and whether the report shows enough detail to explain the result. A single age value can be hard to act on if it doesn't show which parts of the model influenced it.
AgeRate is described as a CLIA-validated test processed in a CLIA- and CAP-certified lab. Treat the report as wellness information and review medical concerns with a licensed clinician.
The app-based habit support is a potential fit if you want a test paired with prompts to work on routines. Still, no app can establish that a lifestyle change caused a score to move. Sleep, recent stress, timing, and sample variation can affect biological measurements. Follow the collection directions and avoid comparing results taken under very different conditions.
Confirm AgeRate's current price and turnaround time before purchase. Think of this option as a molecular readout with an app layer, rather than a substitute for routine blood work or an evaluation of symptoms.
EasyDNA uses a saliva sample and one proprietary clock. That makes it a less invasive option for someone who would rather collect a sample at home than have a blood draw. Its main limitation is the narrow view: a single clock does not provide the cross-check of several different clocks or a multi-system blood panel.
Saliva-based epigenetic tests analyze DNA methylation from cells collected in the mouth. The sample type can make collection simpler, but it doesn't make the estimate a complete measure of health. Follow the kit instructions and don't overread a single score.
For a consumer, the main concern is that one proprietary score offers little room to compare different clocks or see why they disagree. That doesn't make the result meaningless; it means you should be careful about using it to judge a small change.
A saliva clock may fit a person who values easy collection and wants a simple age estimate. It is less suited to someone trying to understand heart, metabolic, hormone, or nutrient markers. For those questions, a blood panel gives a different kind of information, though it also cannot diagnose a condition by itself.
Whichever sample you choose, keep the test's purpose in view. A biological age number can start a conversation about habits, but it cannot tell you which supplement to take or prove that a lifestyle change will extend your life.
Key Takeaway: Biological age tests measure different things, so compare the method and intended use, not only the final age number.
No single consumer test is proven to be the most accurate for every person or purpose. DNA methylation clocks, glycan tests, and blood panels measure different things. Accuracy depends on what the test was built to estimate and how well that model performs for your question. Check its validation details, then treat the result as one piece of health information.
A higher biological age means the test's chosen markers or model produced an estimate above your chronological age. It doesn't prove that you have a disease or predict exactly how long you'll live. Review the method and any component results, then discuss concerns with a clinician who knows your health history.
It may help you track a signal over time, but one change in score doesn't prove that a habit caused the change. Results can vary with the test method and sample conditions. Keep notes about major changes, follow the same collection instructions, and avoid frequent retesting that may capture short-term noise.
Choose based on the question you want answered. Blood tests can measure routine health markers or specific immune-protein patterns. Saliva and urine are sample types used by some epigenetic tests. A sample that's easier to collect doesn't automatically make the result more useful; check what the test measures and what it leaves out.
If you want a broad view of blood markers across body systems, Vitals Vault is a sensible place to start; if you want a specific molecular aging signal, choose the test built for that question. Before ordering, write down what you hope to learn and plan to review any concerning result with a clinician.
