Food intolerance laboratory test

Food intolerance laboratory testing is done by taking blood sample from the patient. We examine the level of IgG antybodies produced against different foods, one test examines IgG antybodies produced for 54 foods, the other examines them for 108 foods (127 components), and one for 220+ foods.

While the immune system is responsible for the symptoms of food allergies, the symptoms of food intolerance are caused by the digestive system. Food allergies are more dangerous than food intolerances, as in extreme cases a severe allergic reaction can occur, which can even cause death. Food allergies are characterized by an allergen in the food that triggers an immediate reaction from the immune system, while in food intolerance, symptoms appear much more slowly, after hours or even days. An allergic reaction to food does not depend on the amount of food consumed. In food intolerance, the severity of the symptoms that occur depends on the amount of food consumed.

Food-specific IgG antibodies are produced by the immune system when it encounters certain foods. They are a normal part of the immune response to food. Food sensitivity is a general reaction to foods, which may be accompanied by elevated levels of food-related IgG antibodies . IgG antibodies produced by foods do not automatically indicate a disease. Food intolerance is not a disease in itself, but it can result in the exacerbation of symptoms of early inflammatory conditions. Consequently, IgG-antigen-antibody complexes from foods can aggravate a variety of diseases hours or even days after consuming the food (e.g., diseases can affect the gastrointestinal tract, manifest on the skin, cause problems in the central nervous system, brain, respiratory system, or cause metabolic diseases).

Unlike true food allergies, symptoms of food sensitivity can occur even days after consuming the food in question. Due to delayed reactions and non-specific symptoms similar to common illnesses, many people are unaware that they have food sensitivities throughout their lives.

In the case of food allergies, the body’s defense system erroneously reacts to certain foods as if they were harmful, so the cells of the immune system produce antibodies to defend against the foreign substance. In most cases, the allergic reaction produces immediate symptoms. Symptoms can be mild and severe. Itching of the skin, hives, eczema, diarrhea, nausea, bloating, stomach pain, chest pain, swollen airways, shortness of breath, suffocation, asthma, laryngitis and anaphylaxis (severe, life-threatening hypersensitivity reaction) may occur throughout the body. In this case, the level of the specific IgE molecule that causes the allergy is examined. Elevated IgE levels may justify allergy.

There is no need to arrive for the blood sampling on an empty stomach.

If the test is not a follow-up, but is performed for diagnostic purposes, it is not recommended to follow any special diets (e.g. gluten-free, lactalbumin-free) before the test.

The result contains both a quantitative (quantified) and a reference value.

FOX Food Intolerance Test (Food Xplorer) – The Next Generation of Molecular Food Intolerance Diagnostics

Troublesome bloating, chronic digestive complaints, unexplained headaches, or skin problems are often caused by food intolerance. Without laboratory measurement, identifying it is extremely difficult, as symptoms may appear even days after the food in question has been consumed. The FOX (Food Xplorer) test uses state-of-the-art nano-bead technology to measure levels of food-specific IgG antibodies produced by the body. From a single small sample, we can obtain a precise picture of which components trigger an inflammatory immune response in the body.

One of the greatest advantages of the FOX test is its uniquely broad and up-to-date analytical spectrum. Whereas the previously widespread, well-known Food Intolerance 220+ component assay examines approximately 220 food proteins from conventional extracts, the FOX test analyses a total of 287 food antigens from 13 different food groups. FOX screens not only classic domestic ingredients, but also so-called new-wave foods that have become common in modern diets — including various plant-based milks, chia seeds, exotic spices, algae, and plant proteins.

From a technological standpoint, FOX represents a significant advance: in contrast to classic technologies based solely on whole-food extracts, the FOX test employs molecular, recombinant protein antigens in addition to crude food extracts. This molecular approach yields substantially more accurate results, reduces the risk of false-positive measurements and cross-reactions, and thus provides a far more targeted picture of true intolerances.

After the investigation, the patient does not receive merely a report of raw data, but a colour-coded, well-structured assessment supported by intelligent software analysis (RAVEN). Medicare complements this with a free dietary consultation. This detailed diagnostic background provides a precise basis for compiling an effective elimination diet, eliminating unnecessarily strict, unjustified food exclusions and facilitating a return to symptom-free everyday life.
