What are home DNA tests and how do they work?

DNA testing is no longer an exclusive domain of science fiction or secret laboratories. The rapid development in the field of genetics has brought it closer to people to help them discover crucial information about themselves and their health.


Being able to determine how well you tolerate stress, metabolize caffeine, or even if those daily poached eggs are good for your body, has seemed like something of out sci-fi movies. However, advancements in DNA testing have made finding it out not only possible but also completely safe. Getting your analysis is now as simple as ordering a book online. Only this book will be written exclusively for you!

Although genetic testing can be used for a wide variety of purposes, from cracking old criminal cases to identify parentage, home DNA tests are used to determine your predisposition for diseases, diet, and sport. As more and more people realize that the ultimate answer to how to best live their lives lies in their genome, learn more about home DNA tests and join them!


How does it work?

A genetic variation is a change in the nucleotide sequence of a gene, and when it occurs, it affects that gene’s capability of producing proteins it codes for. Genetic testing, therefore, analyzes the changes in chromosomes, genes, proteins, or their metabolites. When doing a personal DNA analysis, we analyze more than 100 sites (loci) of your DNA. At a specific site of your DNA, nucleotide C can be replaced by T. Because we have two copies of each gene, the genetic variation can occur in one copy, both of them, or none at all. This type of variation, at a specific DNA site, is called the genotype. Therefore, we have three possible genotypes: CC, CT or TT, and they are one of the most important factors which make people different!

There are many home DNA tests on the market, but not all of them are worth their money. You have to make sure that their promises and results are backed with real science, certified methods and labs, and ironclad security. While there is no direct danger to you, choosing an unqualified provider of DNA test means throwing your money out the windows and placing your valuable genetics information in inappropriate hands.

Our DNA tests were created using the highest quality and security standards and employing state-of-the-art technology to interpret your results. Keep reading to discover exactly what happens from the moment you order the test to when you receive your results!



Our home DNA tests come with a certified DNA sample collection kit. It can be used by anybody and requires no special handling or storage. The detailed instructions guide you through a simple process: a cheek swab, which provides saliva and epithelial cells from your mouth. Then you send your sample to the laboratory and your work is done. No risk, no blood, no needles!



What happens to your DNA sample at the lab?

GenePlanet genetic tests are based on genotyping the individual’s genetic material, evaluating the results, and providing recommendations and action plans based on your specific needs.

Genetically we are almost identical, but in each gene, there are points of variation. The most common type of variation is a single base change at a particular position – this variation is called a Single Nucleotide Polymorphism, or SNP (pronounced »snip«).

You might think that genetic variations are rare, but in reality, there are up to 5 million SNPs in one human genome! This abundance makes them ideal genetic markers for discovering an individual’s genetic predisposition for various diseases and other traits. We only use genetic markers which have been proven by scientific studies to actually have an effect.


Your information is completely confidential

We take information security very seriously. Especially because we are dealing with the most private and sensitive information about a human being – their very genetic code. All the data we deal with is stored and handled according to the highest EU and local security standards. Your sample is destroyed after the analysis, and the report is stored under an anonymous identification code.


How reliable are home DNA tests?

You might wonder how a simple cheek swab can tell us so much. No invasive reaching into the depths of your body and you get all that information? Yes – that's the beauty of science!

But while there are certain predispositions written in your genes, developing those conditions is not written in stone. Many of them, such as heart disease, type 2 diabetes, obesity, and Alzheimer's disease are a combined consequence of your genetics and your environment. This means that while you might have a predisposition for obesity, it doesn't mean you will inevitably get overweight. Following the recommendations in your DNA test report, your doctor's instructions, and, of course, general guidelines for a healthy life, you can keep your weight and all other possible health problems in check!

Knowledge is power, and knowledge encoded in our DNA gives us control over our lives. By knowing the risks, we can direct our lifestyle and ensure the best possible outcome.
