What you can specifically learn

The range of information is impressive and can be tailored specifically to your interests. Instead of relying on vague assumptions, you get a scientifically sound foundation for your everyday life.

Here are some of the most exciting areas that can be analyzed:

• Metabolism & Nutrition: Find out how your body processes fats, proteins, and carbohydrates. This information is invaluable for finally finding a diet that truly suits you and putting an end to endless diet frustration.
• Nutrient requirements: Are you genetically predisposed to a deficiency in certain vitamins or minerals? With this knowledge, you can specifically optimize your nutrient intake and noticeably boost your energy levels.
• Fitness & Recovery: Learn about your genetic muscle type and find out which sports deliver the best results for you. At the same time, you'll receive valuable tips on how to optimize your recovery after training.

The insights from a DNA analysis are not rigid rules, but a powerful tool. They give you the opportunity to adapt your lifestyle so that it aligns perfectly with your biology.

This guide will walk you through how easy it is to take a DNA test, step by step. If you would like to explore the basics in more depth first, you will find clear background information in our article Genetics Made Simple. We answer all the important questions—from choosing the right test to interpreting your results.

Which DNA test is really right for you?

When you are considering taking a DNA test, you face a crucial question: What exactly do you want to find out? The world of genetic tests is vast, but the true value only emerges when the test is perfectly aligned with your personal goals. Think of it as choosing the right tool—with a hammer, you will not get far if you want to tighten a screw.

Your motivation is the key here. Perhaps you have already tried countless diets, but the major success you hoped for never came. You are frustrated and wondering why. In exactly this case, a DNA metabolism analysis would be the ideal choice. It reveals how your body processes fats, carbohydrates, and proteins at the genetic level.

Your goals determine the right test

Imagine discovering through a mybody® metabolism test that your body is genetically predisposed to process carbohydrates less efficiently. This one simple insight can completely transform your dietary strategy. It provides the foundation for a targeted and sustainable change—from mere guesswork to informed knowledge.

To make the decision easier for you, we have outlined a few typical scenarios to show which test might suit you best:

• Your goal is weight management: You want to finally understand why you struggle to lose weight despite exercising and counting calories. A metabolism test reveals which macronutrient type you are and how your body responds to certain foods.
• Your goal is more energy & well-being: You often feel tired, lack motivation, or struggle with concentration. A test focusing on nutritional genetics can show whether you have a genetic predisposition to deficiencies in certain vitamins (such as B12 or D) or minerals.
• Your goal is fitness & performance: You are physically active and want to take your training to the next level. A fitness DNA test analyzes genetic markers for your muscle type, recovery ability, and endurance performance.

Your DNA is not your destiny, but your own personal map. It shows you the most efficient route to your health goals by revealing where your strengths lie and which detours you would be better off avoiding.

Choosing a specific test ensures that you receive concrete, immediately actionable recommendations instead of generic platitudes. Rather than general advice, you receive an individual roadmap based on your unique genetic profile. That is the crucial difference between general health advice and a personalized strategy that truly works.

This is how easy ordering and sample collection are

You have decided to take a DNA test and are now wondering what happens next? Don't worry—the entire process is surprisingly straightforward. You can conveniently do everything from home—without visiting a doctor and completely painlessly.

As soon as you order the right test for you online at mybody-x.com, your personal test kit will be on its way. It usually takes just a few business days to arrive. This package contains everything you need for the next step.

A look inside your test kit

As soon as you open the box, you will notice that every detail has been carefully considered. Instead of complicated instructions, you will find clear, intuitive equipment.

The kit usually contains:

• A sample tube: This is where your saliva sample goes. It is packaged sterile and very easy to use.
• Detailed instructions: They guide you with images through every step—from collecting the sample to securely packaging it for shipping.
• An activation code: This unique code is your key to pseudonymizing the data. It ensures that your privacy remains 100% protected.
• A prepaid return envelope: Use it to send your sample free of charge directly to our certified partner laboratory in Germany.

This infographic shows you how to find the right test for your goals—whether it concerns metabolism, nutrients, or your fitness.

It is clear here that choosing the right test is the first and most important step on your path to personalized health.

Sample collection—how to do it safely

Now comes the most important part: collecting your saliva sample. To ensure that the laboratory can analyze clean, uncontaminated DNA, there is one golden rule: Wait at least 30 minutes after your last meal, drink, cigarette, or toothbrushing.

My tip from experience: Make it easy for yourself and collect the sample first thing in the morning after getting up. This ensures that it is free from contaminants and that the laboratory analysis runs smoothly.

Next, activate your kit online using the enclosed code. This step is crucial because it pseudonymizes your sample. This means that the laboratory works only with this code, without knowing your name or other personal information. Your privacy is therefore protected at all times. Germany’s high standards are well established, by the way—for example, the Federal Criminal Police Office’s DNA analysis database had grown to over 1,183,000 records by May 2024, underscoring the reliability of genetic procedures in Germany.

Once everything is complete, place the sealed tube in the return envelope and take it to the post office. That’s it! You can also find more detailed instructions in our Instructions for carrying out a DNA test.

What happens to your DNA sample in the laboratory

As soon as you send your test kit on its way, the truly fascinating part begins. Your sample does not simply end up in some machine; it is handled by scientists in a highly specialized, certified laboratory. From this point on, precision is essential.

First comes DNA isolation. Millions of cells float in your saliva sample, and each one carries your complete genetic blueprint. In the laboratory, biochemical methods are used to separate the DNA cleanly from everything else floating around in the cell—proteins, fats, and other “cellular waste.” In the end, pure, highly concentrated DNA remains. This is the raw material for everything that follows.

From sample to digital data set

The amount of DNA obtained from a saliva sample is tiny—far too little for a thorough analysis. That is why it must be multiplied. This is done using a method called polymerase chain reaction (in short: PCR). Essentially, it is like a high-performance genetic copier that produces billions of identical copies from just a few DNA strands. This ensures that the experts have enough material for an entirely error-free evaluation.

The actual analysis follows: genotyping. This is where state-of-the-art analytical equipment comes into play, reading your genetic code at thousands of predetermined positions. These positions are not chosen at random but are scientifically relevant to the questions addressed by your test—for example, your metabolism, nutrient utilization, or athletic predisposition.

How can you recognize a good laboratory? It’s simple: by its certification. Reputable providers work exclusively with laboratories certified according to strict standards such as ISO 17025. This guarantees the highest scientific standards, precision, and reliable results.

What about data protection and security in the laboratory?

One crucial point that is often overlooked: How secure is your data once it is in the laboratory? A reputable provider such as mybody® ensures that your sample is processed exclusively in pseudonymized form. Laboratory staff therefore see only your unique activation code—never your name or other personal data.

And what happens to your sample after the analysis? This is where the good providers separate themselves from the less reputable ones:

• Sample destruction: Once the analysis is complete, your biological sample is professionally and securely destroyed. This ensures that it can never be used for other purposes.
• Secure data transfer: Your raw genetic data is transmitted to the provider in encrypted form. This is the only way to create your personal results report without third parties being able to access it.
• No data trading: Your genetic information belongs to you. It will never be sold or shared without your explicit consent with third parties such as insurers or pharmaceutical companies.

This transparent and meticulous process guarantees not only scientifically sound insights, but also the reassuring feeling that your sensitive data is protected throughout the entire process.

How to properly understand and use your results report

At last, it has arrived—the moment you have been waiting for. After all that curiosity, you are holding your personal results report in your hands. But what now? A good report is far more than just a collection of scientific data. It is your very own roadmap to a healthier you.

That is exactly what matters to us at mybody®: We want you not only to understand your results, but also to be able to put them into practice immediately in everyday life. Forget complex tables and incomprehensible jargon. Your report is clearly structured, visually presented, and full of specific recommendations based directly on your unique genetics.

What your mybody® report specifically reveals

We have divided your report into logical sections so that you can easily understand the various facets of your body. Each section provides knowledge that you can put to immediate use.

A few examples of what you will learn:

• Your personal metabolic type: Does your body respond better to proteins or carbohydrates, or are you a classic mixed type? This single piece of information is already worth its weight in gold when it comes to finally aligning your diet with what your body can process most efficiently.
• Your optimal nutrient intake: The report shows you in black and white whether you have a genetically increased need for certain vitamins or minerals. This allows you to specifically prevent deficiency symptoms instead of merely guessing.
• Your fitness potential: Find out which sports best suit your genetic muscle type and how to optimize your recovery. This way, you can get the most out of your training.

See your results as a powerful tool for self-optimization. This is not a medical diagnosis, but a scientifically sound foundation for finally tailoring your diet and lifestyle to your needs.

Such analyses used to be unaffordable. According to the Bavarian Ministry of Justice, a DNA expert report can still cost between €1,200 and €1,500 per analysis. But thanks to standardized procedures, providers like mybody® can now offer this at a much lower price. Preventive health optimization is therefore no longer a luxury.

From insight to action

But the most valuable part of your report is the personalized recommendations. You learn not only that, for example, you are a carbohydrate type. We also provide very specific suggestions about which foods are ideal for you and how to put together your meals intelligently.

Your report is the starting point. The insights it provides give you back control and empower you to make informed decisions. It is about no longer blindly following every trend, but finding an approach that is perfectly suited to your biology. To help you get started, we have prepared a guide on how to optimally adjust your diet after receiving your test results.

You are probably wondering: What is really behind a DNA test?

When you consider taking a DNA test, a lot of questions quickly come to mind. That is a good thing, because it shows that you are consciously engaging with your health. To give you greater peace of mind, we answer the questions we at mybody® are asked most frequently here.

How secure is my genetic data, really?

To be perfectly clear: Data protection is the be-all and end-all here. With a reputable provider, you can assume that your data is protected by multiple security barriers—and this starts right at home.

The most important step is pseudonymization. As soon as your sample arrives at the laboratory, it is separated from your name and assigned a unique code. This means the laboratory staff has no idea whose DNA they are analyzing. This ensures maximum anonymity.

In addition, further strict protective measures are in place:

• Encrypted transmission: All your data is encrypted according to the latest standards and processed on servers subject to the strict rules of the European General Data Protection Regulation (GDPR).
• Destruction of the sample: After analysis, your biological sample is properly disposed of in the laboratory. This completely rules out any subsequent unauthorized analysis.
• No sale of data: Your genetic data belongs only to you. It will never be sold or shared with third parties—such as insurance companies or pharmaceutical companies—without your explicit permission.

Can a DNA test predict diseases?

A crucial question that needs a clear answer. The lifestyle genetic tests we offer at mybody® are not medical diagnostic tools. Their purpose is to give you insights into your predispositions—for example, relating to your metabolism, nutrition, or athletic performance.

They show you how your body functions genetically, so you can make targeted improvements to your lifestyle. For example, a test may reveal whether you have a predisposition to a particular vitamin deficiency. However, it cannot predict or diagnose diseases.

A lifestyle DNA test never replaces a visit to the doctor. If you want to investigate symptoms or understand your risk of hereditary diseases, a medical geneticist is the only appropriate person to contact.

And what if I don’t understand the results?

Don’t worry—you won’t be left alone with a jumble of scientific data. A good results report is presented in a way that you can understand even without prior knowledge. Clear graphics, simple explanations, and—most importantly—practical tips for your everyday life are the key.

If any questions remain, a high-quality provider won’t leave you to figure things out alone. At mybody®, for example, you can book a personal consultation with experts. During the conversation, you can calmly review your results, ask follow-up questions, and work together to consider how best to use your new insights.

How accurate is a home test like this, anyway?

The analytical accuracy is extremely high. When your test is evaluated in an ISO-certified laboratory, it is over 99%. This means that the decoded genetic code is absolutely reliable. The technology behind it has been tried and tested for years and has proven its value.

The true quality of a test is shown not only in the laboratory, but also in the scientific interpretation of the data. Reputable providers base their recommendations on a broad range of current, international studies. This is the only way to ensure that the advice you receive is based not only on accurate data, but is also scientifically sound and genuinely useful.
