NutriCheck I Intolerance Test

An IgG test (food intolerance) measures the production of IgG antibodies by your immune system in response to certain foods. These antibodies are a natural response of your body and often appear immediately after consumption. Current scientific evidence suggests that elevated IgG levels could indicate that your body has frequently consumed these products and may have developed an immune tolerance . The test helps you identify potential intolerances.

Once your blood sample has arrived at the lab, the average processing time is approximately 20–25 business days . This includes the entire analysis process as well as the validation of the results. The results will then be available to you as a PDF document in your user account . If you have opted for a printed booklet , please allow an additional 2 to 3 weeks for printing and shipping.

The symptoms can be varied and affect the entire body. They usually appear shortly after consuming the incompatible food. The most common symptoms include:

• Gastrointestinal problems such as diarrhea, abdominal pain and nausea
• skin rashes
• Respiratory problems such as a runny nose, cough, wheezing or shortness of breath
• Tingling, redness and swelling in the mouth, on the tongue and in the throat

In severe cases, anaphylactic shock can occur – a serious allergic reaction that often begins with dizziness and can be life-threatening. This condition requires immediate medical attention. A food intolerance test can detect mild as well as severe symptoms and help avoid them.

Over 170 foods can cause allergic reactions or intolerances. However, the most common triggers include:

• Cow's milk and eggs
• Pulses, especially peanuts and soy
• Tree nuts, especially nuts
• Wheat
• Fish and shellfish

Less common, but still known, are allergies to fruits, vegetables, and spices. Many of these food allergies appear in childhood. Some, such as those to cow's milk, eggs, wheat, and soy, often disappear during adolescence. Allergies to nuts, fish, and shellfish, on the other hand, usually persist throughout life. You can easily find out which products are currently causing you problems by taking a food intolerance test at home.

There is an important difference between food intolerances and food allergies, which can affect symptoms and test results.

Food intolerances are often based on delayed immunological reactions (IgG-mediated) and manifest themselves through nonspecific symptoms such as digestive problems, headaches, or fatigue. These symptoms often appear hours or days after consuming a particular food.

In contrast, food allergies are generally characterized by immediate reactions, often occurring right after consuming an allergenic food. These allergic reactions are usually mediated by IgE antibodies and can lead to symptoms such as swelling of the mucous membranes, skin rashes, or breathing difficulties.

Using the test kit, you take a few drops of blood from your fingertip and send the sample to the lab. There, your blood is tested for specific IgG antibodies against over 80 foods. The at-home food intolerance test is simple, reliable, and provides you with concrete recommendations for action.

If you regularly suffer from digestive problems, skin reactions, or nonspecific symptoms after eating, a food intolerance test can be helpful. The test also provides important insights into your diet in cases of unexplained weight gain, fatigue, or chronic ailments.

After the food intolerance test, you will receive a personalized evaluation with recommendations on which foods you should avoid. Based on the results, you can then implement a targeted elimination diet , reducing or replacing problematic foods. This will help relieve your digestive system and effectively alleviate symptoms such as bloating, skin problems, or fatigue.
