Review of the Science Behind myDNAge Test

Epigenetics refers to the field of science that deals with heritable changes in the genome that are not the primary DNA sequence. These modifications play a role in biological aging, such as metabolism and disease progression. Experts often use DNA methylation, the most abundant and best-studied epigenetic modification, as a representation of biological age. To this end, Dr. Steve Horvath created an analytical method based on 353 CpG (DNA Methylation) sites that serves as a biological aging clock.

Epigenetic modulation
Epigenetic modulation

Epimorphy currently owns the exclusive license to these DNA methylation sites, and myDNAge uses most of them in their biological age test. Each methylation site can be either methylated (1s) or unmethylated (0s). The Hovarth clock applies the pattern of methylation across a person’s DNA in sequences of 1s and 0s.

The company’s algorithm compares it with patterns from people at different stages of life, providing customers with a personalized biological age predication.

Factors like genetics, lifestyle, diet, and environment can influence epigenetic modifications, like DNA methylations. Thus, understanding biological age can help customers take action to protect or manage these risk factors, improving health and quality of life.

Review of myDNAge Tests

myDNAge sells three epigenetic tests: 

  1. Blood Biological Age Test
  2. Urine Biological Age Test
  3. myDogDNAge Biological Age Test

The first two tests provide a similar output, with the difference being in sample collection (blood vs. urine). Customers can choose either based on their preference. While the performance of these two tests are very similar, the exact biological age may be different based on the kit used.

This is because the source of DNA is different, with the blood sample using white blood cells (overall immunity) and the urine test using urine (overall urinary tract health).

Blood Biological Age Test

The At-Home Blood Collection Kit is a lancet-based kit that requires 2-3 drops of blood.

There are several advantages to choosing the blood collection over the urine one. Overall, it provides a more complete assessment of the body’s health than urine, which only assesses the urinary tract system. It also quantifies metabolic diseases risks. Finally, it has faster extraction and processing and better accuracy than the urine test.

Urine Biological Age Test

The at-home urine collection kit allows customers to get similar biological age results with the simple collection of urine. Some may prefer this collection method rather than the finger prick.

While the price is the same and the company notes that the results are similar, the blood test has several advantages noted above, including enhanced accuracy. Also, myDNAge Report Version 2 is not available with the Urine Biological Age test.

myDogDNAge Biological Age Test

The biological age test for dog’s was a limited edition available through January 31, 2023. Users collect the DNA sample by using a cheek swab on their dog.

The test was developed by the company’s scientists, using some data from Dr. Steve Horvath’s pan-mammalian clock. When it was sold, it was only available to customers in the United States and took 8 weeks to process.  

Review of Taking a myDNAge Test

Customers order one of the two collection kits from the website, either blood or urine. Once ordered, users will receive their collection device within a week.

Each kit contains instructions on how to collect the blood or urine sample. Then, customers mail it back using the provided prepaid return label. 

Finally, results will be delivered by email in 4-6 weeks.

Taking a myDNAge test

Both testing kits contain an instructional manual, biohazard bag, and prepaid return envelope. However, they differ in some components. For example, the blood test has blood collection tubes, capillary tubes, lancets, gauze pads, alcohol wipes, and bandages. In contrast, the urine test contains non-latex gloves, a transparent cup, a urine collection bottle, and a urine preservation reagent.

Review of myDNAge Cost

The price of any of the test products is $299.

The price includes the testing kit (blood or urine), shipping costs, sample analysis, and data summary report.

Review of a myDNAge Test Reports

The myDNAge report is about 30 pages long and contains five categories:

  • Results
  • Data interpretation
  • Index data interpretation
  • Genetic variants data interpretation
  • Resources

The results are a relatively small part of the report (about four pages) while the majority of the report is dedicated to data interpretation.

DNAge results

The main result is the calculated DNAge. In brief, this analysis of over 2,000 biomarkers compares the customer’s biological age with their chronological age.

This also includes the DNAge index, which compares the customer’s results to others of their same calendar age group and sex.  

The next result is the Epi-Metabolic Index, a score developed to display risk of developing metabolic disorders.

If a customer’s measurement is below the reference point, they are not at metabolic risk. The higher the measurement, the higher the risk.

The final part of the results section focuses on genetic variants. In the report, the company analyzes two SNPs (APOE and MTHFR) that may contribute to aging and thus the reported biological age.

For instance, the APOE gene encodes a protein that helps carry cholesterol and other types of fat in the bloodstream. Some variants are associated with reduced longevity and Alzheimer’s disease. On the other hand, MTHFR encodes a protein that assists with metabolic pathways.

Some customers may not want to know their status on these genes as they are associated with debilitating conditions. Therefore, the results portion of the report will only show the SNP found. Customers will need to find the section of the report under genetic variants data interpretation to learn what their SNP means.


The next three sections of the report go into detail about what the results mean and the science to how the results were calculated. 

The interpretation sections also include improvement plans of ways to better overall health and wellness, which can affect biological age. These include things such as reducing stress and air pollution and improving exercise and sleep.

The last section is a list of references.

Review of myDNAge Privacy Policy

The myDNAge epigenetic age determination service and website are owned and operated by Epimorphy, LLC. 

It claims that customer authorization is needed for it to share the results of the report with third-parties.

When they order a kit, customers provide personal information including name, age and address. None of the information is considered protected health information as defined under federal law. Additionally, kits are de-identified to minimize risk. 

When a customer orders and submits a kit, the company owns  the sample material and may use it and the data generated for any reason including but not limited to sharing with its associated research laboratory, Zymo Research Corp. for improving services.

The company claims that it takes reasonable steps to safeguard personal information but admits that no precautions insure complete security. These include internal and third party physical and technical measures.

Data is stored for a reasonable amount of time to provide services and comply with the law.
