Test for intolerances and finally feel comfortable again

Do you often feel tired or bloated, or struggle with skin problems, and blame it on everyday stress? You’re not alone. But instead of keeping a vague food diary for months, you can also test for intolerances directly and finally understand why your body is rebelling.

Your symptoms could have a clear cause

Do you sometimes feel as though your own body is working against you? A constant feeling of fullness, headaches that come out of nowhere, or skin that simply won’t calm down—these symptoms can make everyday life a real burden. Many of us accept this discomfort as “normal” and learn to live with it.

Yet these vague symptoms often have a clear underlying cause: an undiagnosed food intolerance. This is not about classic allergies with immediate, severe reactions. We are talking about delayed IgG reactions that occur only hours or even days after consuming certain foods.

Your body’s subtle signals

It is precisely this time delay that makes it incredibly difficult to identify the culprit yourself. Who would associate today’s headache with the dinner they had the day before yesterday?

Typical signs that may indicate such an intolerance are varied:

• Digestive problems: Constant bloating, an uncomfortable feeling of fullness, stomach pain, or irregular bowel movements.
• Skin problems: Acne, eczema, unexplained redness, or itching.
• General discomfort: Persistent fatigue and lack of energy, joint pain, or migraines.

These symptoms can occur because your immune system reacts to certain proteins in food and triggers low-grade inflammation in the body. Your body is, in a sense, engaged in a constant, quiet battle of defense.

You don’t have to simply accept these symptoms. A blood test can be the first crucial step toward regaining control over your well-being and finally interpreting your body’s signals correctly.

The easy way to gain clarity: Your mybody-x test

In the past, identifying food intolerances was often a test of patience: lengthy doctor’s appointments and complicated elimination diets that required a great deal of discipline. Fortunately, there is now a modern and convenient alternative—a blood test you can take at home. With a simple intolerance test from mybody-x.com, you can discreetly collect a small blood sample without much effort.

This sample is then analyzed in a certified laboratory to measure your personal IgG reactions to a wide range of foods. Instead of continuing to guess, you receive a clear, data-based report showing which foods could be responsible for your symptoms.

Imagine finally finding the cause and being able to adjust your diet accordingly to sustainably improve your quality of life. It is the most direct way to live in harmony with your body again.

Which intolerance test is right for me?

So you’ve decided to get to the bottom of the cause of your symptoms—great! But now you’re faced with the next question: Which test is right for you? There are various ways to identify intolerances, and not every method is suitable for everyone. Let’s bring some clarity to the testing jungle together.

The most important factor is the type of your symptoms. Do you experience severe immediate reactions after eating, such as sudden swelling, shortness of breath, or a severe skin rash? Then seeing a doctor is essential. The aim here is to rule out a classic allergy with an IgE test. Such tests should always be performed by medical professionals.

An overview of the most common testing methods

However, symptoms are much more often less dramatic, developing gradually and appearing with a delay. This is exactly where the following methods come in.

This table shows the differences between the most common testing methods so you can find the best method for you.

Comparison of testing methods for intolerances

Test method	What is tested?	Advantages	Disadvantages
IgG blood test (mybody-x)	Delayed IgG antibody reaction to many foods	Comprehensive (up to 154 foods), fast, convenient to do at home, clear overview	Not suitable for diagnosing classic allergies (IgE) or enzyme deficiencies
H2 breath test (at the doctor’s office)	Specifically for lactose, fructose, or sorbitol intolerance	Scientifically recognized for specific carbohydrate intolerances	Time-consuming (several hours), tests only one substance, appointment required
Elimination diet	The body’s reaction to avoiding certain foods	Cost-effective, with a direct connection between avoidance and symptoms	Very time-consuming and laborious, requires a high level of discipline and is difficult to maintain
IgE blood test (at the doctor’s office)	Immediate allergic reactions (type I allergy)	Gold standard for diagnosing true allergies	Does not detect delayed intolerances (IgG)

So, every method has its merits. While visiting a doctor is the right approach for acute allergies, other options are available for diffuse, chronic symptoms.

The classic but often tedious approaches

Perhaps you’ve already heard of these two methods:

• The H2 breath test: This is performed by a doctor to specifically identify lactose, fructose, or sorbitol intolerance. You drink a test solution, and the hydrogen level (H2) in your breath is then measured over several hours. Many people find this quite time-consuming, especially since only one substance is tested at a time.
• The elimination diet: This is the traditional approach, but it requires a great deal of discipline. You strictly avoid suspected foods for weeks and keep a detailed diary to see whether anything improves. It is effective, but often a real challenge in everyday life.

Deciding whether a test makes sense at all can be very simple. If you have unclear symptoms, a test is the logical next step.

The modern way: The mybody-x IgG at-home blood test

A modern and, above all, convenient alternative is an IgG-based at-home blood test, such as the one from mybody-x. This test focuses on delayed reactions of your immune system. Your body may react to certain foods by producing IgG antibodies, which often leads to low-grade inflammation and typical diffuse symptoms such as bloating, headaches, or skin problems.

The key advantage: You avoid weeks of diet-related guesswork and hours of waiting at a doctor’s office. With just a few drops of blood from your fingertip, you can have your reaction to up to 154 different foods analyzed at the same time. All from the comfort of your own home.

This method is perfect for quickly gaining a comprehensive overview and tracking down potential culprits. And the issue is more relevant than ever: A Statista survey on the prevalence of food intolerances shows that around 18 percent of people in Germany are affected.

The mybody-x test gives you a clear, data-based foundation for your next steps without immediately turning your life upside down. If you’re still unsure, our guide can help you determine which test is right for you.

How the mybody-x test works at home

Have you chosen a home test to finally get answers about your symptoms? Great, because this puts you in control of your health. We will show you how easily you can gain clarity with the mybody-x intolerance test—without waiting rooms, directly from your couch.

The thought of having blood drawn initially puts many people off, but don't worry: The entire process is designed to be quick, simple, and as painless as possible. You will find everything you need right in your test kit.

Your test kit: The start of a new relationship with your body

Once you have received your mybody-x kit, simply unpack it at your leisure. Inside, you will find detailed, illustrated instructions that guide you through everything step by step. The most important components are:

• Two lancets: These little helpers create a tiny, precise prick in your fingertip. The prick is barely noticeable—more like a brief pinch.
• One blood collection tube: This is where you collect the few drops of blood needed for the analysis.
• Swabs and bandages: Use these to cleanly and safely care for the small puncture site afterward.
• One return envelope: It is already stamped and prepared for the safe transport of your sample.

Collecting the sample itself takes only a few minutes. My tip: Choose a finger on your non-dominant hand. Wash your hands well with warm water beforehand; this stimulates circulation and makes collection even easier.

From finger prick to laboratory

Once you have collected the blood drops in the tube, seal it securely and pack everything according to the instructions. Then place it in the return envelope and take it to the nearest mailbox. Shipping to our certified partner laboratory in Germany is of course free of charge for you.

As soon as your sample arrives at the laboratory, it is analyzed under the highest quality and data protection standards (GDPR & ISO-27001). Your data is completely secure with us and is processed only anonymously.

The IgG antibodies in your blood are then tested in the laboratory for reactions with up to 154 tested against various food extracts. This method creates an accurate profile of your personal intolerances. So you no longer have to spend weeks guessing or giving things up just in case.

Within a few days after your sample reaches us, you will receive a notification. Your results will then be available in your personal, secure mybody-x health portal. There you will find an easy-to-understand report showing you exactly which foods might be triggering reactions in your body.

For anyone who wants to know every detail, we have also prepared a detailed guide to conducting a blood test at home that explains every step once again. This is how simple the path to greater well-being can be.

Understanding and making targeted use of your results

The test is complete, and the analysis is in front of you—now the most exciting part of your journey toward greater well-being begins. At last, you have it in black and white which foods your body might be reacting to. But what exactly should you do with all the charts and values in your mybody-x health portal?

We deliberately designed your test report so that you can understand it at a glance. You will see a clear classification of your IgG reactions into different levels: mild, moderate, or strong. Think of this classification as your personal guide.

What the reaction levels mean for you

Don’t worry—a reaction to a food does not mean that you have to avoid it forever. Instead, see it as an opportunity to give your body a conscious break and listen closely to what it is telling you.

• Mild reaction: Your body is showing only a minimal response here. Often, it is enough to eat these foods less frequently—for example, only once or twice a week instead of daily.
• Moderate reaction: This is where you should take a closer look. It is a good idea to eliminate these foods completely for a while, for example 4–8 weeks. This gives your gut time to calm down.
• Strong reaction: Foods in this category are the main suspects for your symptoms. Consistently avoiding them for at least 12 weeks is the best way to give your system a genuine opportunity to recover.

This targeted omission is also known as a rotation or elimination diet. The idea behind it is simple: You give your immune system a break and give your intestinal lining the opportunity to regenerate.

Your test result is not a final verdict. It is the starting point for positive change—and finally gives you back control instead of leaving you in the dark.

Specific steps after the test

After studying your report, it is time to put it into practice in your everyday life. The key to success is to consistently avoid the identified foods for the recommended period. This may initially sound like a challenge, but it can bring enormous relief, especially in the case of widespread intolerances. A 2021 KKH study, for example, showed that diagnoses of lactose intolerance increased by 61%. While classic methods such as the H2 breath test are often time-consuming, mybody-x makes testing for intolerances at home with a simple blood test much easier. You can read more about this study in this Deutschlandfunk article.

Once the elimination phase is over, reintroduction begins. Gradually reintroduce the avoided foods into your diet one at a time and in small quantities, and carefully observe how your body reacts. Do you still feel good? Great! If old symptoms return, you have very likely found the trigger.

This approach has already helped more than 11.300 of our customers improve their symptoms noticeably. Your mybody-x result is therefore far more than just a list—it is your very own personal guide to a better sense of well-being and a higher quality of life.

When you should also see a doctor

A mybody-x home test is a fantastic tool for getting to the bottom of your symptoms and gaining data-based insights into your body. Think of it as your personal health detective, helping you identify patterns and adjust your diet strategically. But it is just as important to know the limits of self-diagnosis and when seeing a doctor is simply unavoidable.

Your mybody-x intolerance test is designed to detect delayed, IgG-mediated reactions. These are often the hidden culprits behind vague complaints such as bloating, constant fatigue, or skin problems. However, seeing a doctor is essential if you are experiencing severe or acute symptoms.

When a medical diagnosis is essential

There are clear warning signs from your body that you should never ignore. In these situations, a home test cannot replace a medical examination, but may at most complement it.

Pay particular attention to the following signs:

• Severe immediate reactions: You eat something and shortly afterward suddenly experience shortness of breath, tightness in the throat, swelling of the face, or a severe skin rash (hives). These are typical signs of a true, IgE-mediated allergy, which requires immediate medical attention.
• Severe chronic symptoms: Persistent, severe abdominal pain, unintended and significant weight loss, chronic diarrhea, or even blood in the stool are serious symptoms. Comprehensive medical diagnostics are required in these cases.
• Suspected celiac disease: If you suspect that gluten is causing severe gastrointestinal problems or deficiency symptoms, this must be confirmed or ruled out by a doctor.

A home test provides valuable guidance to test for intolerances. However, a medical diagnosis is indispensable if serious illnesses or classic allergies are suspected.

The perfect complement to your doctor’s visit

The distinction between an allergy and an intolerance is fundamental because the reactions in the body occur in completely different ways. While true food allergies affect only around 4% of the population, up to 30% experience reactions that are often attributable to intolerances. You can find more information about the prevalence of food allergies on allergieinformationsdienst.de.

The mybody-x blood test specifically focuses on IgG-mediated intolerances to finally provide clarity about symptoms such as bloating or skin irritation.

Think of your mybody-x test as a valuable supplement. The results can provide your doctor with important additional information, especially if other examinations have not produced clear findings. It is the ideal starting point for optimizing your lifestyle, while your doctor remains the specialist for complex diagnoses and illnesses. If you would like to learn more about the exact differences, also read our article on the difference between an allergy and an intolerance. This way, you can make the best use of both approaches for your health.

What you should know about the intolerance test

If you’re considering taking a food intolerance test, you probably have a few questions swirling around in your head. That’s completely normal! We hear these questions every day and have compiled the most important answers for you here—honest and to the point.

Are IgG tests really meaningful?

We hear this question often, and it is absolutely valid. In nutritional and complementary medicine, IgG tests are an incredibly useful tool. They help identify the possible culprits behind vague symptoms such as constant fatigue, skin problems, or digestive issues. However, it is important to note that such a test does not replace a medical diagnosis of a classic allergy or a condition such as celiac disease.

The countless positive responses are the best proof for us. The experiences of more than 11.300 Customers show that changing their diet based on the test leads to noticeable improvements for many people.

See your test results as a starting point. They provide the data you need to create a plan that is truly right for you and helps restore your well-being.

Should I avoid certain foods before the test?

Quite the opposite! For meaningful results, it is especially important that you eat as normally and diversely as possible in the weeks before the test. So please eat everything you normally eat.

The reason is logical: Your body only produces IgG antibodies in response to foods it comes into contact with. So if you already avoid a particular food because you suspect it, the test cannot detect it—even if an intolerance is present.

How quickly will I notice a change when I change my diet?

There is no one-size-fits-all answer, because every body is different. How quickly you notice your first results is as individual as you are.

Some of our customers report feeling tremendous relief after just a few days, especially when it comes to digestive problems such as constant bloating. They suddenly feel lighter and have much more energy.

For other issues, especially skin concerns such as acne or eczema, it can sometimes take several weeks or months before the appearance of your skin visibly improves. Skin cells renew more slowly, so a little more patience is needed here.

Give your body the time it needs. Consistency is key here.
