How TeloYears Works

Measuring the length of your telomeres comes down to four simple steps:

  • Information collection Before you can order the testing kit, you’ll need to enter your contact and payment information and answer a couple of simple questions to ensure the right fit of TeloYears.
  • Information review and placing your order – The provided information will then be reviewed by a highly-qualified doctor, who’ll also place the order for you. Telomere Diagnostics Inc. uses an independent team of physicians, all authorized to order your genetic test. The at-home sample collection kit will then arrive at your address within one week.
  • Sample collection  The TeloYears test is done by processing a blood sample. You’ll need to collect one drop of your blood, following the provided instructions, and send it back via the pre-paid envelope.
  • Results Once complete, your results will be sent to you via e-mail, 3-4 weeks after the sample reaches the lab.

The TeloYears at-home testing kit comprises the following elements:

  • Pink Finger Stick lancet
  • 1-drop blood collection strip
  • Yellow-top transport tube
  • Alcohol wipe
  • Gauze pad
  • Adhesive bandage
  • Pre-paid mailing envelope

The actual testing protocol includes measuring telomere length in your DNA via the quantified polymerase chain reaction (qPCR), the most accurate and scientifically referenced method in the field.

Telomeres shorten at different rates during our lifespan, affected by lifestyle, disease, environmental influences, and a slew of other factors. Dr. Blackburn thus recommends repeating the test every 6 to 12 months to ensure the proper monitoring of your DNA wellness.

  • Gift cards available


The TeloYears DNA Test costs 129$. There is also an option to purchase their “Now and Later” pack, including two tests, saving you 20$. The first test is used to determine your TeloYears baseline age and the second one monitors the results of your life improvement during the period of 6 or 12 months. The only “constraint” is the fact that both tests must be used by you. The test can also be ordered as a gift.

The test processes a single drop of your blood for both convenience and reliability. A single blood drop contains more than 50k cells, which ensures perfect test accuracy. That’s why TeloYears doesn’t use saliva or buccal swabs.

The procedure analyzes your DNA located in the white blood cells (leukocytes). It does that by using their proprietary and unique method named the “Cawthon qPCR assay.” The science behind the method is rather perplexing, but it comes down to exploiting specific telomere primers to quantify the telomeric signal ratio, relative to the solitary copy of the gene signal. The T/S ratio will reflect the ATL (average telomere length) in your circulating blood.

Telomere Diagnostics Inc. has developed its proprietary ways of tackling the delicate nature of the qPCR telomere length assay regarding the collection of the sample, its storage, preparation for processing, and assay conditions. They apply a multitude of normalization procedures and standards, aimed at ensuring the ultimate accuracy and precision of the assay. The result is a very reliable measurement, with a variability coefficient between 2-3 percent.

Lastly, your ATL is entered into a mathematical formula derived by the company, enabling them to calculate your TeloYears age. This calculation reflects the actual age of men and women with telomere length similar to yours.

Understanding The Results

Apart from the conventional test report, TeloYears also offers a “Blueprint for Aging Well” as an added benefit.

TeloYears results will allow you to determine your current cellular age and monitor the overall vitality of your cells. The report itself includes:

  • Your ATL (average telomere length) and a comparative view to other people of your age and gender.
  • Your specific age in TeloYears, which will be calculated as the actual age of men or women with similar telomere length as you.
  • Tracking your results over time, which is especially useful for repeated testers.

Blueprint for Aging Well is a bonus which condenses decades of scientific research into a simple and tabulated resource. It’s a very insightful too and it includes:

  • A tool for self-assessment, which should raise your awareness of specific, actionable factors that affect your TeloYears age. This will both inspire and guide you through their proper management.
  • Detailed explanations to help you understand how your lifestyle, inflammation, stress, and other factors influence telomere shortening.
  • A suggested action plan, based on your test results. The plan will offer recommendations regarding eating well, sleep, stress, physical activity, and more, covering the range from novice to expert.
  • A comprehensive view of telomere science applied to your case. Besides practical uses and known limitations, the role of telomeres in age-related diseases will also be explained.


Telomere Diagnostics Inc. is a very active company in the scientific research department. They constantly work on improving our understanding of telomeres, their impact on our wellness, and all the factors that expedite their shortening process.

The most notable research projects include:

  • A study performed on 468 US Military veterans, supported by the Department of Veteran Affairs. The study focused on telomere shortening related to hostilities, especially difficulties with anger control.
  • A study supported by the National Institutes of Health and performed on 586 healthy sisters age 35-74. The study established a correlation between multivitamin use and longer telomeres.
  • A NASA-supported study, performed on more than 20 astronauts. It determined the impact on telomere length caused by space travel and offered a comparative view with those staying Earthbound.
  • A Harvard University supported study, which was performed on 4,676 women nurses. The study established the association between the Mediterranean diet and longer telomeres.
  • A study supported by the U.S. Army and performed on 650 special operations soldiers. It found a link between telomere shortening and depression, traumatic stress, and PTSD.
  • A University of California supported a study conducted on 5,309 US adults (age 20-59), which drew a causal relationship between consumption of sugar-sweetened sodas and telomere shortening.
