TeloYears DNA Test

Co-founded by Dr. Elizabeth Blackburn, who won the Nobel Prize in 2009 for her studies of telomeres, TeloYears offers DNA ancestry testing as well as a very unique approach to health testing. Rather than looking for genetic variants that could indicate higher risk for certain diseases and health conditions, TeloYears looks at an entirely different component of your DNA-telomeres-to provide information about your biological age (which can be different from your chronological age).

Review Summary


  • One of two major testing companies to offer both ancestry and health DNA testing
  • CLIA-certified
  • Fully actionable health information, meaning that you can use it to improve your health starting right away
  • The only company that aims to reveal your biological age
  • Built-in privacy of sensitive health data
  • Uses next-generation DNA sequencing


  • Regional granularity isn’t as good as 23andMe or AncestryDNA (with the notable exception of East Asia)
  • TeloYears health test not yet available in the state of New York
  • Maryland residents need an additional form completed by their healthcare provider
  • No genealogical community

Bottom Line

TeloYears is a great company for giving you a unique perspective on your health, one that you can actually use in order to get healthier. It also offers above-par DNA ancestry testing at a decent price. The ancestry testing is particularly good if you believe you have East Asian ancestry, but you’ll have to take your results elsewhere in order to connect with relatives or other genealogy enthusiasts.

Our Top Picks


TeloYears offers DNA ancestry testing as well as a very unique approach to health testing. Dr. Elizabeth Blackburn, who won the Nobel Prize in 2009 for her studies of telomeres Co-founded TeleYears.

Once you fill out the online form, TeloYears gets to work. If you order a health test kit, TeloYears consults with a doctor to confirm that you are a suitable candidate for the test (if you’re taking the ancestry testing only, this step doesn’t happen).

Pricing and Options

TeloYears offers several product options:

TeloYears Health Report

This retails for $79 (see updated price), plus shipping and handling. It’s great for people who just want the health data and don’t feel that they will need personalized advice (or for those who plan to consult with their healthcare provider).

TeloYears + TeloCoach

A package that includes the TeloYears health report plus the TeloCoach feature (more on that below). Great for people who want help developing an action plan based on their results and lifestyle.

Advanced Ancestry

The TeloYears ancestry DNA test kit costs $79 (see updated price), for those who don’t want to take the health test but want to learn about their ethnic heritage.

TeloYears + Advanced Ancestry

For $139 (see updated price), you can buy both the standard health test and the ancestry test (does not include TeloCoach). The best of both worlds.


Because TeloYears health reports provide health information that encourages you to make life adjustments in order to improve, customers often like to re-test. There’s a discount for that! If you want to use the “Now and Later” option, you can buy two TeloYears health tests for $30 off, or $139. The company recommends that you take the first test, examine your results, and then take the second test six months or a year later, in order to see the results of your lifestyle changes.

Seasonal discounts are very common when it comes to home DNA test kits, so your best bet is to check the latest price. Holiday discounts are particularly common as shoppers look for good gift ideas

Why TeloYears Testing Works

You may remember little about telomeres from high school biology. Even if you do remember them, you may not know exactly what they can tell you about your health and how testing actually works.


Think of telomeres as tiny protective caps at the end of your chromosomes (threadlike strands of DNA). TeloYears itself suggests we think of the plastic caps at the end of shoelaces.

Every cell in your body contains your DNA; otherwise, for one thing, the cell wouldn’t contain the necessary genetic coding for it to replicate and pass along to new cells when a cell divides. This would be a major problem! Every strand of DNA has a telomere at each end.

The cells in our bodies divide to produce new cells; this cell division occurs until cells reach a state of “senescence,” which means they can no longer replicate. But why?

Well, each time a cell divides, a full replica of your DNA is donated to the new cell, BUT… the little telomeres don’t replicate fully. Instead, a little bit of their substance is lost with each replication. This means your telomeres are getting shorter as a natural process of cellular aging, in a way.

That’s what “senescence” actually is, for a cell; your telomeres get too short for cell division to occur anymore.

TeloYears Telomeres

Actionable Information

Natural cell division isn’t the only process that shortens your telomeres. Lots of other things do this as well, such as stress, diet, fatigue, and lack of exercise.

Not only that, but evidence suggests that lifestyle decisions can slow the telomere-shortening process down, just as they can accelerate it. This is a two-way street. In other words, if you develop a plan to introduce positive changes in your lifestyle—maybe improving your diet, finding better ways to manage stress, and so forth—you can slow down your cell aging. It’s a great way to look at overall health and make improvements because it’s measurable! That’s how TeloYears can rightly claim to offer actionable health test results. You can use them in order to shave years off your biological age.

DNA Sequencing vs. Genotyping

There’s an important difference between genotyping and new-generation DNA sequencing. Both are methods used to analyze your DNA and produce test results. Other DNA test companies use genotyping, but TeloYears is proud to use DNA sequencing instead. Why is this a matter of pride?

If you think of your DNA like a really detailed book, then:

  • Genotyping would be scanning the pages looking for specific words in specific places. If the word “Titanic” appears in the second paragraph of the second page and “James Cameron” appears on that same page, then maybe we know something important about this page of text.
  • Sequencing, however, collects chunks of text and whole sentences from that page and throughout the book.

Why is this important? It allows TeloYears (a company without the largest database) to provide more granular ethnicity regions than Family Tree DNA, for instance, so the method clearly has merits. But it’s possibly more important when it comes to the future study of DNA results. To continue with the “pages in a book” metaphor, genotyping can look for words that we know to be significant now, but what about all the words that will prove to be significant only later? Genetic science advances in leaps and bounds seemingly every year; it’s almost certain that we’ll know far more in a few years than we do now. In that sense, your TeloYears data could have a longer, more meaningful shelf-life than other data.

Submitting Your DNA

Once you fill out the online form, TeloYears gets to work. If you order a health test kit, TeloYears consults with a doctor to confirm that you are a suitable candidate for the test (if you’re taking the ancestry testing only, this step doesn’t happen). Then the company mails your kit and it arrives in the mail within a week of ordering (ours arrived in less than a week).

After that, you simply follow the instructions in the kit, waiting the required amount of time after eating. Unlike other big at-home DNA testing companies, TeloYears uses blood in order to get results. This is because there are tens of thousands of cells in a single droplet of blood, making results potentially more accurate. Simply give your finger a tiny prick and collect the droplet of blood. Don’t worry, it’s painless and easy—no different than when a diabetic person checks blood glucose levels.

After collecting the drop or two of blood, mail the kit back in the pre-paid envelope. You’ll get results of the health test in 3-4 weeks, while the ancestry test requires the typical 6 to 8 week delivery time. For us, the deliveries fell early within those windows.

A Few Complications to Note

  • You have to be between the (chronological) ages of 20 and 80 in order to take the TeloYears test.
  • The test is unavailable in New York State.
  • If you live in Maryland, you’ll need your healthcare provider to fill out another form for you to submit in order to get the kit.

Reports and Features

If you opt for the health test by itself, your test results will arrive within 4 weeks. They will contain a straightforward report summarizing your results, along with a “Blueprint for Aging Well.” The summary of the health test tells you your average telomere length, as well as how that value compares to the overall average telomere length of people your age and gender.

Then, based on these details, it gives you your age in TeloYears, which is the indicator of your biological age as opposed to chronological age. Your TeloYears age might be lower than your chronological age, higher, or roughly the same.

The Blueprint is a packet of information explaining the science behind this form of testing, as well as the actionable steps you can take to address lifestyle factors that evidence suggests play a role in telomere length and biological age. You can answer the standard questionnaire in order to steer yourself toward the most fruitful paths for improving your biological age.

TeloYears Reporting

TeloYears + TeloCoach

The results of this package will include all of what you receive from the standard TeloYears kit, but you will also benefit from a scheduled one-on-one meeting with a TeloYears health coach. This is actually very valuable because the Blueprint you otherwise receive is not tailored to you personally. The health coach listens to you, learning about your lifestyle, and then gives you the best advice about how to make the most meaningful improvements. Essentially, this tailors your improvement plan specifically to you, for maximum benefit. If you don’t opt to include TeloCoach, be sure to discuss the results of your health test with your healthcare provider in order to gain this level of insight.

Advanced Ancestry Report

The ancestry test results take longer to arrive than the health results—6 to 8 weeks. You can learn a lot of fascinating information, though! Pie charts break down your ethnic heritage. Multiple organized levels of ethnicity regions allow for better contextual understanding and ease of browsing your results. Advanced Ancestry reports also include information about your maternal and paternal haplogroups, along with historical migration patterns mapped out for you.

Other Considerations


One thing that sets TeloYears apart from competitors is that its proprietary methods don’t reveal any medical or health information that you’d prefer to keep private. The company obviously protects all of your data from privacy breaches, but even if all the raw data were somehow exposed, nobody could use it to gain any insight into your disease risks, etc. There would be nothing sensitive to gain. Beyond that, TeloYears vows never to share your data with a third party.

Regional Reporting

The regional breakdown of this company’s autosomal (ethnic heritage) ancestry reporting can’t compete across the board with AncestryDNA or 23andMe, both of which far exceed 100 regions in their reporting. But TeloYears does a better job than FTDNA with its regions. When it comes to heritage in certain parts of the world, such as East Asia, TeloYears positively excels compared to all of them. Don’t just settle for “East Asian”, “Chinese”, or “Japanese”; find out how much of your ethnic heritage is Oroqen, Mongolian, Hezhen, or the many other possibilities.

Genealogical Community

In this case, TeloYears doesn’t compete at all, and it’s important for you to be aware of this before buying. For serious genealogical pursuits, you’ll want to take your ancestry data from here and upload it to a third-party database, where you’ll be able to connect with others who have taken similar tests elsewhere.

Data Exportability

Thankfully, TeloYears makes it easy for you to export your ancestry DNA results, allowing you to compensate for the lack of a support community.

TeloYears vs. 23andMe

It stands to reason that people will compare these two companies because 23andMe is famous for offering a combination of health and ancestry reporting. If your sole interest is ancestry, you’d probably be better off with a different company than either of these.

So how does TeloYears hold up to comparison with a major rival? Let’s find out.

Health Testing

When it comes to health reports, maybe you should order both. These companies’ approaches to health testing are radically different, but both are useful.

  • 23andMe offers what many would consider to be the traditional approach—insight into your personal genetic health risks based on variants found in your DNA, as well as whether you are a carrier of certain recessive genes that could potentially pose health risks to your children if your partner is also a carrier.
  • TeloYears takes a totally different approach. It doesn’t delve into the potential health significance of gene variants but instead tells you about your average health at the cellular level: whether you’re keeping pace with your chronological age or are actually older or younger in a very meaningful, biological sense.

Both companies provide valuable information. Which path you find more rewarding is a matter of preference. Some find the TeloYears information to actually be more useful for making life changes that improve their health picture.

Ancestry Testing

When it comes to ancestry reports, 23andMe has a clearer edge, with one notable exception.


23andMe offers more regional granularity in its ethnic heritage reports, except when it comes to East Asia (which is a major population area). TeloYears claims that this is a result of smart database-curating along with the next-generation DNA sequencing that TeloYears uses, as opposed to the traditional genotyping of 23andMe and other companies.


23andMe doesn’t have much of a genealogical community, so it is similar to TeloYears in that sense.

Deep Ancestry

23andMe offers the three traditional ancestry tests—yDNA, mtDNA, and autosomal—while TeloYears offers just the one ancestry test. However, its genome-wide DNA sequencing methodology combined with its curated database allows it to give the broad ethnicity details while also diving into your maternal and paternal haplogroups. Both companies charge the same price. We found the outcomes to be equally edifying, but both tests left us wanting to connect with others in a community to continue our learning.

Bottom Line: Which One to Choose?

You may not like the answer, but it’s a toss-up, a matter of personal preference boiling down to which types of health information you find more useful and meaningful. If your real interest is strictly health testing, and you can afford the price tags, you would gain the fullest health information possible by taking both the TeloYears test and the 23andMe health test package; they are not at all redundant, and both are informative. Since you have to buy the 23andMe ancestry package in order to buy its health test, you could skip TeloYears’ ancestry test and stick to the health offering.
