Our view

TellMeGen offers comprehensive DNA testing for in-depth analysis of health and ancestry. It reveals predispositions to over 200 monogenic diseases, including Alzheimer’s and certain cancers, and sheds light on ways to minimize risk. Thanks to an intuitive user interface, customers benefit from detailed information and personalized advice. Subject to strict EU regulations, the company guarantees optimum data security and confidentiality, and 99.99% reliability of results. However, it does not offer the possibility of creating a family tree. For this, we recommend that you opt for MyHeritage DNA, whose results are much more accurate and offers you the option of creating your own family tree.

A few words about TellMeGen

TellMeGen is a laboratory specializing in autosomal DNA testing based in Valencia, Spain. Founded in 2006, the company combines scientific expertise and advanced technology to offer detailed analyses of health and ancestry. TellMeGen stands out for its innovative services and accuracy, which has earned it the trust of thousands of people. The company focuses on preventing hereditary diseases, improving well-being and offering treatments tailored to the diagnoses.

The DNA tests offered by TellMeGen


TellmeGen offers two DNA kits: the starter kit and the Advanced kit. For each kit, the laboratory uses microarray technology to analyze over 750,000 SNPs (Single Nucleotide Polymorphism) on the human genome. This method provides valuable health information and raw data on an individual’s ancestry, genealogical and ethnic origins.

TellmeGen Starter DNA Kit


TellMeGen’s DNA Starter Kit offers a complete analysis of your ancestry and personal traits (health and physical conditions). It details your ethnic origins back 200,000 years and examines over 750,000 genetic markers and 90 genetic traits.

Three main tests are possible with this kit: 

  • An autosomal test to discover your geographic origins among 53 population groups around the world
  • A mitochondrial test (on the X chromosome) to find out your maternal lineage
  • yDNA test (on Y chromosome) to determine paternal lineage

This DNA starter kit also allows you to perform a comparison of your DNA with that of Neanderthal man to identify similarities. As well as revealing your personal traits, it studies your reactions to 30 nutrients(minerals, vitamins…). The kit also assesses your physical reactions (muscle recovery, endurance…) and allergic predispositions.

TellmeGen Advanced DNA Kit


TellMeGen’s Advanced DNA Kit is a complete DNA testing package. It combines all the services offered by the starter kit, but completes with over 400 reports. Indeed, the advanced kit analyzes your genetic predispositions to 59 pathologies such as asthma, Alzheimer’s, Parkinson’s, hypertension and several cancers (pancreatic, thyroid, colorectal prostate). 

It also assesses the risks associated with 97 hereditary monogenic diseases (Beta Thalassemia, cystic fibrosis…). What’s more, this advanced DNA kit studies your body’s pharmacological compatibility with 171 drug molecules. All this information makes it possible to anticipate and prevent certain diseases for personalized medical care.

How the TellMeGen DNA test works

The way TellMeGen DNA tests work, is not that different from other laboratories. You simply need to follow a well-defined process.

Ordering the DNA kit


Go to the official laboratory website to choose the kit of your choice. Then fill in the order form with your full name and contact details. In this way, the kit will be dispatched rapidly to the desired address. For French residents, direct ordering on the site is not possible.

However,you can purchase the TellMeGen test on Amazon Germany and have it delivered to your home.

Sample collection

As soon as you receive your package in the post, start by creating your user account. To do this, scan the QR code in the instruction booklet or visit the official website. You must now register your kit by entering the identification code on the swab reservoir or in the instruction booklet. 

For sample collection, be sure not to eat, drink or smoke 30 minutes before sampling. Fill the tube with saliva up to the black line, then close it with the cap. You can use the swabs to make sampling easier.

Send to lab and analyze samples

Once the kit has been registered and the sample taken, you must return this sample for laboratory analysis. You will receive an e-mail with a link to download the label you will need to send your sample to the laboratory. Print the label received by e-mail and stick it on the plastic bag of your kit.

Place the tube(s) with the saliva sample(s) in the box, then put the box inside the bag. Prepare the package, and take it to the courier office we indicate in the e-mail.

Release results

Results are available over 4 to 6 weeks on your personal online space. These are available in PDF format, easy to download, print or save on a USB key. Please note that before opening your results, you can decide what information you would prefer not to appear.

Results provided

The online portal displays the findings of the Spanish laboratory. These results can be classified into two main categories, namely: health and ancestry reports.

Ascendancy report


TellMeGen analyzes your DNA against thousands of individuals from various ethnicities and reference groups. The test studies the genetic markers of over 74 ethnic groups worldwide. It reveals your ethnic heritage and traces the migratory movements of your ancestors over 3,000 years. You’ll also discover your maternal and paternal haplogroups. On their digital interface, you’ll find a map displaying the proportions of your ethnic origins. By clicking on the buttons on the left, you’ll get more details about your ancestry.

Health report


After analyzing your samples, TellMeGen presents you with a complete health report divided into 5 categories as follows: 

  • Genetic predisposition to disease ;
  • Pharmacological compatibility ;
  • Susceptibility to inherited monogenic diseases ;
  • Health traits.

The TellMeGen dashboard is easy to understand. Simply click on items to obtain detailed information (risk level, appropriate treatment for your health).

Other features

In addition to these two reports, TellMeGen offers other interesting services and features to help you better understand your genetic universe. 

The advice and consultation service

TellMeGen offers an advice and consultation service based on your health reports. The aim of this service is to educate and support you in the face of genetic diseases. To achieve this, the company puts you in touch with nutrition experts and geneticists to benefit from consultations and advice. This way, you’ll know the risks associated with your disease, the implications for future generations and the compatibility of your medications with your genetics. 

DNA Connect


DNA Connect is a feature offered by TellMeGen that uses your ancestry report to find genetic matches. 

This feature lets you connect and compare your genetic information with other users. This can help you identify genetic relationships, DNA matches, or even common ancestors.

You can use this service to track down long-lost family members, discover shared ethnic origins. It can also be useful for finding out more about your own genetic heritage by comparing it with that of others.

The genome exploration tool

The genome mining tool is a huge database regularly updated by TellMeGen. You can download your raw genetic data in CSV format and access a service called Raw data. This service offers the ability to analyze raw genetic data from other companies such as 23andme, Ancestry, MyHeritage, among others.

TellMeGen is able to analyze this data, provided it is coded according to certain specifications. Using this service, you can obtain several reports on your health, personal traits and well-being. You can discover your genetic origins and even use the DNA Connect service to find genetic relatives.

Our opinion of TellMeGen

We think TellMeGen offers a complete, educational and secure experience for those wishing to explore their DNA. Their modus operandi is similar to that of other laboratories. However, TellMeGen stands out for its clear instructions for sample collection and turnaround time. 

The online platform provided is rich in information and intuitive to use. Although their ancestry data is detailed, it seems less comprehensive than that of EasyDNA or Ancestry DNA. TellMeGen’s real strength is its health report. It covers over 200 hereditary conditions and 400 genetic characteristics. 

This information is presented clearly, detailing various genetic predispositions. In terms of value for money, TellMeGen outperforms many competitors. In addition, their transparency regarding data protection and compliance with European regulations inspire confidence.
