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 46 foods, the other examines them for 108 foods (127 components), and one for 220+ foods. IgG (immunoglobulin) type antibodies are produced by the body against foods in case you have food intolerance.

In case of our 40 food intolerance package, we examine food-specific IgG4 levels.

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.

The symptoms of food intolerance can be extremely diverse. Diarrhea, bloating, severe flatulence (gastrointestinal complaints), hay fever may occur up to several hours or days after eating, as well as headaches, migraines, chronic fatigue, joint complaints, and skin problems such as acne.

Food intolerance is caused by intestinal problems. If intolerance is suspected, the presence of a so-called food-specific IgG molecule is examined. Intolerance can be justified in case of a positive result.

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.

On the 5th workday from the time of sampling.

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

The cause of lactose sensitivity is the lack of lactase or its insufficient function. If lactose in the small intestine cannot be broken down into simple sugars, fermentation through changes in the bacterial flora of the colon will result in gas formation.Lactase can be found in the cells of the small intestine.

Lactose consists of two simple sugar molecules. It has a glucose (glucose) and a galactose component, which are linked by a chemical bond. As long as the double sugar molecule cannot get through the epithelial cells of the gut, the simple sugars are able to do so and thus get into the bloodstream. The test is performed by smearing the oral mucosa.

The enzyme deaminooxidase (DAO) in the body is responsible for breaking down histamine. In the absence or reduced function of the enzyme, the degradation is very slow, which causes the accumulation of histamine. The assay measures the enzyme concentration of deamino oxidase. Decreased DAO levels may indicate histamine intolerance. The results obtained should be evaluated in the light of clinical symptoms.

There is no need to arrive for the test 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.

Food intolerance is a problem affecting an increasingly large percentage of the population nowadays. Fortunately, more and more tests are available to filter out foods that cause intolerance. With our 220+ food intolerance test, we quantitatively examine more than 220 foods and their potentially intolerance-causing additives. The test examines several major food groups, which are the following: milk and dairy products, fishes and seafood, fruits, medicinal herbs and herbs, various meats and vegetables, oilseeds and cereals.

The result of a food intolerance test alone is not yet sufficient to make a diagnosis. Our dietitian is at your disposal to develop a proper lifestyle and eating habits.
