Intolerance Test to Find the Cause of Your Symptoms
An intolerance test is a diagnostic procedure that helps you gain clarity. It analyzes which foods your body may be reacting to with delayed, IgG-mediated responses. Mybody-x.com's blood tests can thus uncover the often hidden cause of diffuse symptoms such as bloating, skin problems, or constant fatigue.
Understand Your Body's Signals and Find the Right Test
Do you often feel tired and unwell after eating? Do you constantly struggle with bloating, abdominal pain, or unexplained skin rashes? You are not alone. Many attribute such symptoms to stress or a hectic daily routine, but the true cause is often an unrecognized food intolerance.
This section is intended to serve as a compass to help you better interpret your body's signals and understand how you can take control of your health. First things first: not every reaction to food is the same. We must clearly distinguish between a delayed intolerance and a true, immediate allergy.
Allergy or Intolerance? A Crucial Difference
Imagine it simply: a classic allergy is like a loud fire alarm in your body. As soon as the trigger is present, the siren goes off – immediately, unmistakably, and often with severe symptoms such as swelling, shortness of breath, or severe itching. Your immune system immediately sounds the alarm with so-called IgE antibodies.
A food intolerance, on the other hand, is much quieter, more like a persistent, gentle knocking. The symptoms often appear hours or even days later. They are less dramatic, but often chronic: constant fatigue, digestive problems, or blemished skin. Here, your body forms other antibodies, namely of the IgG type.
This "knocking" is easily overlooked or misinterpreted, but it can severely impair your quality of life in the long run. Because the symptoms are so unspecific and delayed, it is almost impossible to find the culprit without a targeted test. An intolerance test that specifically measures these IgG antibodies finally sheds light on the matter.
Intolerance and Allergy in Direct Comparison
This table shows you the most important differences at a glance, so you can better classify your symptoms.
| Feature | Food Intolerance (IgG) | Food Allergy (IgE) |
|---|---|---|
| Reaction time | Delayed (hours to days) | Immediate (minutes to 2 hours) |
| Immune system | IgG antibodies involved | IgE antibodies involved |
| Symptoms | Chronic, diffuse (e.g., digestive problems, fatigue, headaches, skin problems) | Acute, often severe (e.g., swelling, shortness of breath, itching, skin rash, anaphylaxis) |
| Trigger amount | Often depends on the amount | Even the smallest traces are sufficient |
The distinction is therefore not just a subtlety, but crucial for the correct management of your symptoms and the choice of the appropriate test.
Why a Test is the First Step to More Well-being
The distinction between allergy and intolerance is of great practical importance. Estimates suggest that about 15 to 20 percent of the population in Germany suffers from some form of intolerance. True food allergies, on the other hand, are significantly rarer, affecting around 3 to 4 percent of adults.
A targeted test is therefore so important:
- Clarity instead of guessing: You receive a clear evaluation of which foods could trigger an immune reaction in you.
- Targeted measures: Instead of generally avoiding entire food groups, you can adapt your diet specifically and soundly.
- Symptom relief: By avoiding the identified triggers, you give your body the chance to recover and get rid of chronic symptoms.
A blood test that analyzes IgG reactions, such as the mybody®x intolerance test, is a logical and simple first step to regain control over your well-being. If you want to delve deeper into the matter, you can learn more about the exact difference between allergy and intolerance in our article. This will create the basis for a life with more energy and well-being.
The Different Types of Intolerance Tests Explained
If you suspect that certain foods are behind your symptoms, you quickly face an important question: Which test is right for me? The selection of tests can seem overwhelming at first glance, but don't worry – we'll explain the most common methods and what really matters to better understand your body.

Precisely because the symptoms of an intolerance can be so delayed and diffuse, it is difficult to find the trigger without help. A targeted test, which you can easily do at home, is often the decisive step to finally gain clarity.
Blood Tests for Your Body's Immune Response
Blood tests are a central tool for tracing your immune system's reactions. However, one must distinguish precisely between two types of antibodies that are often confused:
-
IgE tests (allergy tests): This test looks for IgE antibodies. They are responsible for classic immediate allergies, where your body reacts violently within minutes – for example, with shortness of breath after consuming nuts. Here, the immune system immediately sounds the alarm.
-
IgG tests (intolerance tests): This test, on the other hand, measures IgG antibodies. These are associated with delayed and often chronic complaints such as digestive problems, constant fatigue, or skin impurities. Such an intolerance test is the mybody®x blood test. It helps you uncover these hidden troublemakers in your diet so you can proactively improve your health.
A positive IgG result is not an allergy diagnosis. Rather, it is a valuable indication that your immune system is reacting to a specific food. This reaction can lead to subclinical inflammatory processes, which in turn cause your symptoms. Find out here how a blood test for food intolerance works.
Interestingly, it turns out that one's own assessment is often deceptive. Although over 12.2 million people in Germany consider themselves allergic, the rate of true, demonstrable food allergies in adults is only 3.7 percent according to studies. This discrepancy makes it clear how important it is to replace assumptions with reliable facts from a test.
Breath Tests for Lactose and Fructose Intolerance
Not all intolerances are an immune system reaction. Sometimes the body simply lacks a certain enzyme to digest sugars like lactose (milk sugar) or fructose (fruit sugar).
For these cases, there is the H₂ breath test, which is usually performed at the doctor's office. You drink a special sugar solution. If your intestine cannot break down the sugar properly, bacteria in the large intestine will feed on it. This process produces hydrogen (H₂), which you exhale. If the H₂ value in your breath rises measurably, it is a clear indication of an intolerance.
Every test therefore has its justification and its special area of application. While breath tests specifically detect problems with sugar digestion, an IgG-based intolerance test from mybody-x gives you a broad overview of your immune system's reactions to a variety of foods.

Understanding Reaction Strengths
Your mybody®x report shows you how strongly your immune system reacts to certain foods by forming IgG antibodies. To give you a quick overview, these reactions are categorized into different levels – often color-coded from green to yellow to red.
- No or low reaction: Everything in the green zone. With these foods, your immune system shows no significant defensive reaction. You can usually enjoy them without hesitation.
- Slight to moderate reaction: Here, a closer look is required. These foods could contribute to your diffuse symptoms, especially if you eat them often or in larger quantities.
- Strong reaction: Your immune system reacts very clearly to these foods. They are the main suspects and should be at the top of the list for your dietary change.
Important to know: The level of the IgG value does not always have to be directly related to the severity of your symptoms. Sometimes a food with only a slight reaction can cause severe symptoms, while another with a strong reaction has hardly noticeable consequences. The test is your starting point – your personal experience in the next step is what really counts.
The Elimination Phase – Your Path to Clarity
After you have analyzed your report, the most important phase begins: the so-called elimination diet. This sounds stricter than it is. Basically, you give your body a conscious break so that it can regenerate and recover.
To do this, you stop eating the foods that showed a moderate to strong reaction in the test for a certain period – usually four to six weeks.
This step has two crucial goals:
- Calm your system: By avoiding potential troublemakers, you relieve your immune system and your digestion. Many feel a significant improvement after a short time – less bloating, clearer skin, or more energy.
- Create a basis: After this phase, your body is, so to speak, "reset." This is the perfect starting point to then specifically find out which foods are really responsible for your symptoms.
During this time, focus on all the delicious things you are allowed to eat without problems, and see it as an opportunity to discover new things.
Tips for a Successful Transition
Changing your diet can be a challenge at first. But with a few simple tricks, you can master it without frustration. It's not about giving up, but about making conscious and smart decisions for your well-being. You will not only get to know new foods but also your own body better.
- Plan your meals: A simple weekly plan with dishes made from "allowed" foods takes the stress out of everyday life and prevents impulsive decisions.
- Read ingredient lists: Unexpected ingredients are often hidden in processed products. A quick glance at the list when shopping will soon become a habit and protect you from surprises.
- Cook fresh: When you cook yourself, you have full control over what ends up on your plate. This is the safest way to avoid trigger foods and at the same time get creative.
Always remember: You are doing this for yourself and your health. If you want to delve deeper into how to correctly classify your values, you will find valuable information in our article on analyzing blood values.
What Comes After the Test? Your Roadmap to More Well-being
Congratulations, the results of your intolerance test are in! Imagine you are holding a very personal map in your hands that shows you the way to more well-being. But a map alone is only the first step – now the real journey begins. We will give you a concrete roadmap on how to successfully integrate these new insights into your daily life.
This path is not a punishment, but a liberation. You learn to make conscious decisions for your body and discover a completely new quality of life. It's about setting the right course for your long-term health.
The Way Back to Balance: The Rotation Diet
After you have taken a break from the foods that showed a reaction during the elimination phase, the next step is to reintroduce them in a controlled manner. A really clever principle for this is the rotation diet. It's like not giving your immune system the same tasks every day, but providing healthy variety.
The goal behind it? Your body should not constantly be confronted with the same potential irritants. This not only prevents new intolerances from developing but also promotes a diverse and strong gut flora. Because variety on your plate is the key to a healthy gut.
Here's how it works in practice:
- Plan for variety: Don't eat a certain food (especially those to which you reacted slightly) on consecutive days. A good rhythm is to eat it only every four days.
- Think in families: To make it easier for you, you can also rotate entire food groups together, for example, nightshades like tomatoes, potatoes, and bell peppers.
- Discover new things: Consciously use rotation to try new, tolerable foods that you may not have considered before.
This method helps to relieve your immune system and slowly but surely rebuild your body's tolerance.
Reintroduction: Observing Step by Step
After the elimination phase, your body is like a freshly wiped slate. Now you can specifically find out which food actually triggers symptoms. This so-called provocation phase is crucial to personally confirm the results of your intolerance test.
Start with a food that the test reacted to. Reintroduce it in a small amount and observe your body very carefully for the next 72 hours. A food diary will be your most important companion.
Pay attention to everything you notice:
- Digestion: Do bloating, abdominal pain, or altered bowel movements return?
- Skin appearance: Do you notice pimples, redness, or itching?
- Energy level: Do you suddenly feel tired, sluggish, or unfocused again?
- Mood: Do you suddenly have headaches or are you irritable without reason?
If you don't notice any symptoms, great! You can slightly increase the amount the next day. If reactions occur, you have found a clear indication. Then stop eating that food again and test the next one on your list after a few days.
Your body doesn't lie. This phase is your chance to experience the direct connection between what you eat and how you feel firsthand. It is an incredibly empowering process that gives you back control over your well-being.

Frequently Asked Questions About the Intolerance Test
The decision to take an intolerance test is a big step towards more well-being. Of course, questions arise – that's completely normal and shows us that you take your health seriously. To clear up any remaining uncertainties, we have summarized the most frequently asked questions and our honest, clear answers for you here.
How reliable is an at-home IgG intolerance test?
An IgG test, which is analyzed in a certified German specialist laboratory like at mybody-x, is extremely accurate in its analysis. The laboratory precisely measures whether and how strongly your immune system reacts to certain foods by forming IgG antibodies.
It is important how you classify this result: It is not a definitive diagnosis, but a valuable guide. Imagine it as a personal map that shows you exactly where potential "stumbling blocks" might lie on your dietary path.
You achieve the greatest validity by combining two things: the scientific laboratory result and your own observation. The test provides you with the perfect starting point for a subsequent elimination diet. This way, you can determine with high certainty which foods are really behind your symptoms.
Do I have to avoid certain foods before the test?
No, quite the opposite! For a meaningful result, it is even crucial that you eat normally and as varied as possible in the weeks before the test.
The reason is simple: Your immune system can only form antibodies against substances it comes into contact with. So, if you have been avoiding wheat for months, for example, the test cannot logically detect a reaction to it, because your body is not currently confronted with it.
So, continue to eat normally. Only then can the test provide an authentic picture of your current physical reactions and give you the best possible basis for your next steps.
What is the difference between a mybody®x test and a test at the doctor's?
This question is particularly important, because the different test procedures are not competitors, but useful additions. The mybody®x intolerance test is an IgG screening that you perform easily from home. It is specialized in finding indications of delayed immune reactions – the hidden culprits behind chronic complaints such as fatigue, skin problems, or digestive disorders.
Medical practices usually focus on two other areas when it comes to food reactions:
- IgE tests (allergy tests): These are used to detect classic immediate allergies (type I), which manifest themselves through rapid and severe symptoms such as those of hay fever.
- H₂ breath tests: These are used when there is a concrete suspicion of lactose or fructose intolerance, i.e., a utilization disorder.
The mybody®x test thus closes an important gap in diagnostics. It provides you with a tool to proactively search for the causes of diffuse symptoms that often go undetected in standard examinations.
An at-home test from mybody-x gives you the opportunity to take the initiative yourself. You quickly and easily gather important initial clues without having to wait for a doctor's appointment. You can then also use these insights to have a more targeted discussion with your doctor or therapist.
Can I also take the test if I have existing illnesses or am pregnant?
Basically, yes. The test can also be carried out during pregnancy or with known chronic illnesses. The results can also give you valuable dietary advice during these phases.
However, particular caution is required here. We strongly advise you to discuss any planned dietary changes in these cases with your treating doctor, midwife, or therapist beforehand.
Especially during pregnancy and breastfeeding, your body has special nutrient requirements. Even with chronic illnesses, an ill-considered change in diet can have negative consequences. An expert by your side ensures that all changes are safe and beneficial for you and – if applicable – your unborn child.
What happens if I don't feel better after changing my diet?
The vast majority of our customers experience a significant improvement after a targeted change. But every body is different. If you don't notice any change after a few weeks, there could be several reasons for this.
- Hidden culprits: Have you carefully checked the ingredient lists of convenience products? Triggers like wheat, milk, or soy are often hidden where you least expect them.
- Cross-reactions: Sometimes the body reacts to foods that are botanically related to a known trigger.
- Other causes: Your symptoms could also be due to other factors such as stress, another undiscovered intolerance (e.g., histamine), or an underlying illness.
Don't give up! See the result as an opportunity to look even more closely. A food diary is worth its weight in gold now. In addition, our mybody®x health experts are at your side. They will help you analyze your results individually and plan the next steps together.
Are you ready to take the decisive step and finally understand your body's signals? Don't wait any longer for answers, find them yourself. Discover with the blood tests from mybody®x how you can actively shape your well-being. Visit us at https://mybody-x.com and start your journey to more energy and quality of life today.
