Intolerance test to find the cause of your symptoms
ca. 20 Minuten
An intolerance test is a diagnostic procedure that helps you get clarity. It analyzes which foods your body may be reacting to with delayed, IgG-mediated responses. Blood tests from mybody-x.com can reveal 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 sluggish and unwell after eating? Do you repeatedly struggle with bloating, stomach pain, or unexplained skin rashes? You’re not alone. Many people blame symptoms like these on stress or the hectic pace of everyday life, but the real cause is often an undetected food intolerance.
This section is meant to serve as your compass, helping you better interpret your body’s signals and understand how you can take your health into your own hands. First things first: not every reaction to food is the same. We need to clearly distinguish between a delayed intolerance and a genuine, immediate allergy.
Allergy or intolerance? A crucial difference
Think of it this way: 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 intense itching. Your immune system sounds the alarm immediately with so-called IgE antibodies.
A food intolerance, on the other hand, is much quieter, more like a persistent, faint knocking. Symptoms often don’t appear until hours or even days later. They’re less dramatic, but often chronic: constant fatigue, digestive problems, or blemished skin. Here, your body produces different antibodies, namely IgG antibodies.
This “knocking” is easy to miss or misinterpret, but can significantly affect your quality of life over time. Because the symptoms are so nonspecific and delayed, it’s almost impossible to find the culprit without a targeted test. An intolerance test that measures these exact IgG antibodies finally sheds light on the issue.
Intolerance and allergy compared directly
This table shows you the key differences at a glance, so you can better identify the cause of your symptoms.
| Characteristic | 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 tiniest traces are enough |
So this distinction is not just a fine point; it’s crucial to managing your symptoms appropriately and choosing the right test.
Why a test is the first step toward greater well-being
The distinction between allergy and intolerance has significant practical implications. Estimates suggest that around 15 to 20 percent of the population in Germany have some form of intolerance. In contrast, true food allergies are much less common, affecting around 3 to 4 percent of adults.
That’s why a targeted test is so important:
- Clarity instead of guesswork: You’ll receive a clear report showing which foods could trigger an immune reaction in your body.
- Targeted measures: Instead of giving up entire food groups, you can make targeted, evidence-based adjustments to your diet.
- Symptom relief: By avoiding the identified triggers, you give your body a 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 toward regaining control of your well-being. If you’d like to delve deeper into the subject, you can learn more in our article about the exact difference between allergy and intolerance. This gives you the foundation for a life with more energy and well-being.
The different types of intolerance tests explained
If you suspect certain foods are behind your symptoms, you quickly face an important question: Which test is right for me? The range of tests can seem overwhelming at first, but don’t worry - we’ll explain the most common methods and what really matters to help you better understand your body.
Because intolerance symptoms can be delayed and vague, it can be difficult to identify the trigger without help. A targeted test you can easily take at home is often the crucial step toward finally getting clarity.
Blood tests for your body’s immune response
Blood tests are a key tool for uncovering how your immune system responds. However, it’s important to distinguish 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-onset allergies, in which your body reacts intensely within minutes—for example, with shortness of breath after eating nuts. Here, the immune system sounds the alarm immediately.
-
IgG tests (intolerance tests): This test measures IgG antibodies instead. These are associated with delayed and often chronic symptoms such as digestive problems, persistent fatigue, or skin blemishes. The mybody®x blood test is one such intolerance 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 particular food. This reaction can lead to low-grade inflammatory processes, which in turn cause your symptoms. Find out here how a blood test for food intolerances works.
Interestingly, people’s own assessments often turn out to be misleading. Although more than 12.2 million people in Germany consider themselves allergy sufferers, studies show that the rate of genuine, verifiable food allergies among adults is only 3.7 percent. This discrepancy highlights the importance of replacing assumptions with reliable facts from a test.
Breath tests for lactose and fructose intolerance
Not all intolerances are an immune system response. Sometimes the body simply lacks a specific enzyme needed to digest sugars such as lactose (milk sugar) or fructose (fruit sugar).
The H₂ breath test, which is usually performed at a doctor’s office, is used for these cases. You drink a special sugar solution. If your gut cannot break down the sugar properly, bacteria in the large intestine feed on it. This process produces hydrogen (H₂), which you exhale. If the H₂ level in your breath rises measurably, that is a clear indication of an intolerance.
Each test therefore has its own purpose and specific area of application. While breath tests specifically detect problems with digesting sugars, an IgG-based intolerance test from mybody-x gives you a broad overview of your immune system’s reactions to a wide range of foods.

Understanding reaction levels
Your mybody®x report shows how strongly your immune system reacts to certain foods by producing IgG antibodies. To give you a quick overview, these reactions are divided into different levels, often color-coded from green through yellow to red.
- No or low reaction: Everything is in the green. Your immune system shows no significant defensive reaction to these foods. You can generally enjoy them without concern.
- Mild to moderate reaction: These foods deserve a closer look. They could contribute to your vague symptoms, especially if you eat them often or in larger quantities.
- Strong reaction: Your immune system reacts very strongly to these foods. They are the main suspects and should be at the top of your list as you change your diet.
Important to know: The level of your IgG value doesn’t always correlate directly with the severity of your symptoms. Sometimes a food that caused only a mild reaction can trigger severe symptoms, while another that caused a strong reaction may have barely noticeable effects. The test is your starting point – your personal experience in the next step is what really matters.
The elimination phase – your path to clarity
After analyzing your report, the most important phase begins: the so-called elimination diet. It sounds stricter than it is. Basically, you’re giving your body a conscious break so it can regenerate and recover.
To do this, you avoid the foods that showed a moderate to strong reaction in the test for a set period of time – usually four to six weeks.
This step has two key goals:
- Calming your system: By avoiding potential troublemakers, you give your immune system and digestion a break. Many people notice a significant improvement after just a short time – less bloating, clearer skin, or more energy.
- Establishing a baseline: After this phase, your body is essentially “reset.” This is the perfect starting point for then identifying exactly which foods are causing your symptoms.
During this time, focus on all the delicious things you can eat without any problems, and see it as an opportunity to discover something new.
Tips for a successful transition
Changing your diet can be challenging at first. But with a few simple tricks, you can manage it without frustration. It’s not about giving things up, but about making conscious, smart choices for your well-being. You’ll learn not only about new foods, but also get to know 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. Taking a quick look at the list while shopping will soon become a habit and protect you from surprises.
- Cook fresh: When you cook for yourself, you have full control over what ends up on your plate. It’s the surest way to avoid trigger foods while also getting creative.
Always remember: You’re doing this for yourself and your health. If you’d like to learn more about how to interpret your results correctly, you’ll find valuable information in our article on analyzing blood test results.
What comes after the test? Your roadmap to greater well-being
Congratulations, your intolerance test results are in! Imagine holding a personal map that points the way to greater well-being. But a map is only the first step - now the real journey begins. We'll give you a practical roadmap for successfully integrating these new insights into your daily life.
This journey isn't a punishment, but a liberation. You'll learn to make conscious choices for your body and discover a whole new quality of life. It's about setting yourself up for lasting health.
The road back to balance: The rotation diet
After taking a break from the foods that triggered a reaction during the elimination phase, it's now time to reintroduce them in a controlled way. A really clever approach is the rotation diet. It's like giving your immune system different tasks each day instead of the same ones, creating healthy variety.
The goal? Your body shouldn't constantly be exposed to the same potential irritants. This not only helps prevent new intolerances from developing, but also promotes a diverse and healthy gut microbiome. Variety on your plate is the key to a healthy gut.
Here's how it works in practice:
- Plan variety: Don't eat a particular food (especially one you've reacted to mildly) on consecutive days. A good rhythm is to eat it only every four days.
- Think in food groups: To make things easier, you can rotate entire food groups together, such as nightshades like tomatoes, potatoes, and peppers.
- Discover new foods: Use rotation intentionally to try new foods you tolerate that you may not have considered before.
This method helps give your immune system a break and gradually, 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 find out exactly which food is really causing symptoms. This so-called challenge phase is crucial for confirming the results of your intolerance test for yourself.
Start with a food that the test reacted to. Reintroduce it in a small amount and carefully observe your body for the next 72 hours. A food diary will become your most important companion.
Pay attention to anything you notice:
- Digestion: Have bloating, stomach aches, or changes in bowel movements returned?
- Skin: Do you notice pimples, redness, or itching?
- Energy levels: Do you suddenly feel tired, drained, or unable to concentrate again?
- Mood: Have you suddenly developed a headache or become irritable for no reason?
If you don't notice any symptoms, great! You can slightly increase the amount the next day. If you have a reaction, you've found a clear clue. Stop eating that food and test the next one on your list after a few days.
Your body doesn't lie. This phase is your chance to experience firsthand the direct connection between what you eat and how you feel. It's an incredibly empowering process that gives you back control over your well-being.

Frequently asked questions about the intolerance test
Deciding to take an intolerance test is a big step toward feeling better. Of course, questions come up along the way - that's completely normal and shows us that you take your health seriously. To put your remaining doubts to rest, we've compiled 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 analyzed in a certified German specialist laboratory, as with mybody-x, is extremely precise. The laboratory accurately measures whether and to what extent your immune system responds to certain foods by producing IgG antibodies.
What matters is how you interpret this result: it is not a definitive diagnosis, but a valuable guide. Think of it as a personal map that shows you exactly where potential “stumbling blocks” might lie on your dietary journey.
You will get the most meaningful results by combining two things: the scientific lab results and your own observations. The test gives you the perfect starting point for a subsequent elimination diet. This will help you determine with a high degree of certainty which foods are really behind your symptoms.
Do I need to avoid certain foods before the test?
No, quite the opposite! For an informative result, it is actually essential that you eat normally and as varied a diet as possible in the weeks before the test.
The reason is simple: your immune system can only produce antibodies against substances it has been exposed to. So, if, for example, you have been avoiding wheat for months, the test logically cannot detect a reaction to it either, because your body is not currently exposed to it.
So keep eating as you normally do. This is the only way the test can provide an accurate picture of your current physical reactions and give you the best possible basis for deciding on your next steps.
What is the difference between a mybody®x test and a test at the doctor’s office?
This question is particularly important because the different testing methods are not competitors but useful complements. The mybody®x intolerance test is an IgG screening test that you can easily take at home. It specializes in detecting signs of delayed immune reactions—the hidden culprits behind chronic symptoms such as fatigue, skin problems, or digestive issues.
When investigating food reactions, medical practices usually focus on two other areas:
- IgE tests (allergy tests): These detect classic immediate allergies (Type I), which cause rapid and severe symptoms such as hay fever.
- H₂ breath tests: These are used when there is a specific suspicion of lactose or fructose intolerance, meaning a problem with metabolizing these sugars.
The mybody®x test thus fills an important gap in diagnostics. It gives you a tool to proactively investigate the causes of vague symptoms that often go undetected in standard examinations.
A mybody-x home test gives you the opportunity to take the initiative. You can quickly and easily gather some important initial information without having to wait for a doctor's appointment. You can then use these insights to have a more focused conversation with your doctor or therapist.
Can I take the test if I have an existing illness or am pregnant?
In principle, yes. You can take the test during pregnancy or if you have a known chronic illness. The results can also provide valuable dietary guidance during these times.
However, particular care is needed here. We strongly advise you to discuss any planned dietary changes in these cases with your treating doctor, midwife, or therapist beforehand.
Your body has special nutritional needs during pregnancy and breastfeeding. Unconsidered dietary changes can also have negative consequences if you have a chronic illness. Having an expert by your side ensures that any changes are safe and beneficial for you and, if applicable, your unborn child.
What if I don't feel any better after changing my diet?
The vast majority of our customers notice a significant improvement after making targeted changes. But every body is different. If you don't notice a change after a few weeks, there may be several reasons.
- Hidden culprits: Have you checked the ingredient lists on processed foods carefully? Triggers such as wheat, milk, or soy are often hidden where you'd 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 undetected intolerance (e.g., histamine), or an underlying condition.
Don't give up! See the result as a reason to take a closer look. A food diary is worth its weight in gold right now. Our mybody®x health experts are also here to support you. They can help you analyze your results 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.
