Intolerance test to identify 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. The blood tests from mybody-x.com can reveal the often hidden cause of diffuse complaints 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 repeatedly struggle with bloating, stomach pain, or unexplained skin rashes? You are not alone. Many people attribute these symptoms to stress or the hectic pace of everyday life, but the true cause is often an undiagnosed food intolerance.

This section is intended to serve as a compass, helping you better interpret your body's signals and understand how you can take charge of your health. 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, impossible to miss, and often with severe symptoms such as swelling, shortness of breath, or intense 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, soft knocking. The symptoms often do not appear until hours or even days later. They are 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 overlook or misinterpret, but it can severely affect your quality of life in the long term. Because the symptoms are so nonspecific and occur with a delay, it is almost impossible to identify the culprit without a targeted test. An intolerance test that measures these IgG antibodies finally brings the cause to light.

Intolerance and allergy compared directly

This table shows you the most important differences at a glance, helping you better understand 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 dependent on the amount	Even the smallest traces are enough

The distinction is therefore not merely a fine point; it is crucial for managing your symptoms correctly and choosing the right test.

Why a test is the first step toward greater well-being

The distinction between allergy and intolerance has major practical significance. Estimates suggest that around 15 to 20 percent of the population in Germany suffer from some form of intolerance. Genuine food allergies, by contrast, are significantly rarer, affecting around 3 to 4 percent of adults.

That is why a targeted test is so important:

• Clarity instead of guesswork: You receive a clear evaluation of which foods could trigger an immune reaction in you.
• Targeted measures: Instead of broadly eliminating entire food groups, you can adjust your diet in a targeted and informed way.
• 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 analyses IgG reactions, such as the mybody®x intolerance test, is a logical and simple first step toward regaining control over your well-being. If you would like to explore the subject in greater depth, you can learn more in our article about the exact difference between allergy and intolerance. This lays the foundation 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 range of tests can seem overwhelming at first glance, but don’t worry—we explain the most common methods and what really matters to help you better understand your body.

Precisely because intolerance symptoms can be so delayed and diffuse, it is difficult to identify the trigger without help. A targeted test, such as one you can easily take at home, is often the decisive step toward finally gaining clarity.

Blood tests for your body’s immune response

Blood tests are a key tool for identifying your immune system’s reactions. However, it is important to 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, in which your body reacts strongly within minutes—for example, with shortness of breath after eating nuts. This is when the immune system sounds the alarm immediately.

• IgG tests (intolerance tests): This test measures IgG antibodies. They are associated with delayed and often chronic symptoms such as digestive problems, persistent fatigue, or skin blemishes. The mybody®x blood test is precisely this kind of intolerance test. It helps you uncover these hidden troublemakers in your diet so that 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 may cause your symptoms. Find out here how a blood test for food intolerance works.

Interestingly, studies show that people’s self-assessments are often inaccurate. Although more than 12.2 million people in Germany consider themselves allergic, the rate of genuine, verifiable food allergies among adults is only 3.7 percent, according to studies. This discrepancy highlights 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 response. Sometimes the body simply lacks a specific enzyme needed to digest sugars such as lactose (milk sugar) or fructose (fruit sugar).

For these cases, there is the H₂ breath test, which is usually performed by a doctor. You drink a special sugar solution, and if your intestines cannot properly break down the sugar, bacteria in the large intestine feed on it. This process produces hydrogen (H₂), which you exhale. If the H₂ level in your breath measurably increases, this is a clear indication of an intolerance.

So every test has its own purpose and specific area of application. While breath tests specifically identify problems with digesting sugars, an IgG-based intolerance test from mybody-x provides 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 warrant a closer look. They could be contributing to your vague symptoms, especially if you eat them frequently or in large quantities.
• Strong reaction: Your immune system reacts very clearly to these foods. They are the main suspects and should be at the top of your list when changing your diet.

Important to know: The IgG level does not always directly correlate with the severity of your symptoms. Sometimes a food that causes only a mild reaction can trigger severe symptoms, while another that causes a strong reaction has hardly any 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. Essentially, you are giving your body a deliberate break so that it can regenerate and recover.

For a specific period—usually four to six weeks—you avoid the foods that showed a moderate to strong reaction in the test.

This step has two key goals:

1. Calm your system: By avoiding potential troublemakers, you relieve the burden on your immune system and digestive system. Many people notice a significant improvement after just a short time—less bloating, clearer skin, or more energy.
2. Build a foundation: After this phase, your body is, so to speak, “reset.” This is the perfect starting point for then finding out specifically which foods are really responsible for 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 a challenge at first. But with a few simple tricks, you can manage it without frustration. It is not about deprivation, but about making conscious and smart choices for your well-being. You will not only learn 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 the ingredient lists: Processed products often contain unexpected ingredients. 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. This is the safest way to avoid trigger foods while also getting creative.

Always remember: You are doing this for yourself and your health. If you would like to delve deeper into how to interpret your results correctly, you can find valuable information in our article on analyzing blood values.

What comes after the test? Your roadmap to greater well-being

Congratulations, your food intolerance test results are here! Imagine holding a personal map in your hands that shows you the way to greater well-being. But a map alone is only the first step—now the real journey begins. We will give you a concrete roadmap for successfully integrating these new insights into your everyday life.

This path is not a punishment, but a liberation. You learn to make conscious choices for your body and discover a completely new quality of life. It is about setting the right course for your long-term health.

The path back to balance: The rotation diet

After taking a break during the elimination phase from the foods that triggered a reaction, the next step is to reintroduce them in a controlled way. The rotation diet is a particularly clever principle for this. It is as if you were not giving your immune system the same tasks every day, but instead creating healthy variety.

What is the goal? Your body should not be constantly exposed to the same potential irritants. This not only helps prevent new intolerances from developing, but also promotes a diverse and resilient gut microbiome. Variety on your plate is the key to a healthy gut.

This is how it works in practice:

• Plan variety: Do not eat a particular food—especially those you have reacted to mildly—on consecutive days. A good rhythm is to eat it only every four days.
• Think in food families: To make things easier, you can also rotate entire food groups together, such as nightshades like tomatoes, potatoes, and bell peppers.
• Discover something new: Use rotation consciously to try new, well-tolerated foods that you may not have considered before.

This method helps 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 find out precisely which food is actually triggering symptoms. This so-called challenge phase is crucial for personally confirming the results of your food intolerance test.

Start with a food that the test reacted to. Reintroduce it in a small amount and observe your body very closely for the next 72 hours. A food diary will become your most important companion.

Pay attention to anything you notice:

• Digestion: Do bloating, stomach pain, or changes in your bowel movements return?
• Skin: Do you notice pimples, redness, or itching?
• Energy level: 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 do not notice any symptoms, great! You can easily increase the amount the next day. If reactions occur, you have found a clear indication. Stop eating the food again and test the next one on your list after a few days.

Your body does not lie. This phase is your opportunity to experience firsthand the direct connection between what you eat and how you feel. It is 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 major step toward greater well-being. Naturally, questions may arise—and that is completely normal and shows that you take your health seriously. To put your remaining doubts to rest, 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 that, as with mybody-x, is analyzed in a certified German specialist laboratory is extremely accurate in its analysis. The laboratory precisely measures whether and to what extent your immune system reacts 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 along your dietary journey.

You get the most meaningful results by combining two things: the scientific laboratory findings and your own observations. The test provides the perfect starting point for a subsequent elimination diet. This allows you to determine with a high degree of certainty which foods are actually behind your complaints.

Do I need to avoid certain foods before the test?

No, quite the opposite! For a meaningful result, it is actually crucial 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 come into contact with. So if, for example, you have avoided wheat for months, the test logically cannot detect a reaction to it either, because your body is not currently exposed to it.

So continue eating normally. This is the only way the test can provide an authentic picture of your current bodily reactions and give you the best possible basis for your next steps.

What is the difference between a mybody®x test and a test performed by a doctor?

This question is particularly important because the various testing methods are not competitors but useful complements. The mybody®x Intolerance Test is an IgG screening test that you can easily perform at home. It is specifically designed to detect indications of delayed immune reactions—the hidden culprits behind chronic complaints such as fatigue, skin problems, or digestive disorders.

When it comes to food reactions, medical practices usually focus on two other areas:

• IgE tests (allergy tests): These detect classic immediate allergies (type I), which manifest through 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, i.e. a disorder in processing these sugars.

The mybody®x Test thus fills an important gap in diagnostics. It gives you a tool to proactively investigate the causes of diffuse complaints that often remain undetected in standard examinations.

A mybody-x home test gives you the opportunity to take the initiative yourself. You can quickly and easily gather important initial insights without having to wait for a doctor’s appointment. You can then use these findings to have a more focused conversation with your doctor or therapist.

Can I also take the test if I have existing illnesses or am pregnant?

Generally, yes. The test can also be carried out during pregnancy or in the case of known chronic illnesses. The results can provide you with valuable dietary guidance during these phases as well.

However, particular care is required here. We strongly advise you to discuss any planned change in diet in these cases with your treating physician, midwife, or therapist in advance.

During pregnancy and breastfeeding in particular, your body has special nutritional needs. An ill-considered change in diet can also have negative consequences in the case of chronic illnesses. Having 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 do not feel any improvement after changing my diet?

The vast majority of our customers notice a significant improvement after making targeted changes. However, every body is different. If you do not notice any change after a few weeks, there may be several possible reasons.

• Hidden culprits: Have you carefully checked the ingredient lists of processed foods? Triggers such as 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 attributable to other factors such as stress, another undetected intolerance (e.g., histamine), or an underlying condition.

Don’t give up! See the result as an opportunity 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 will help you analyze your results individually and plan the next steps together.
