Immunosuppressants, which are generally administered after an organ transplant, weaken the immune system and thus the body's ability to produce antibodies. High doses of steroids also have an effect on antibody production. If you are taking medications such as Prednisone, Chloroquine or Azothioprine, do not test while taking these medications. Common allergy medications such as antihistamines (Claritin, Zyrtec, Benadryl) do not affect the result of food intolerance tests, as our tests do not measure the level of histamine, but the immune response. However, be careful with histamine tests. Antivirals such as Valtrex also do not affect the test result. Do not take the test if you are taking antibiotics. After picking them up, it is recommended to wait at least two weeks before testing. Enzyme supplements do not affect the result. If you have any doubts, please contact one of our partners who works with us.

In some cases, testing in groups is permissible. These are SEPEA ELISA SCREEN 40,109 and Food Detective tests. e.g. watermelon and yellow. These are related proteins, therefore, if necessary, it is advisable to eliminate both.

It is necessary to fill it at least 1/3. Otherwise, it is possible that we will ask you to subscribe again. We will send you a replacement set free of charge. There is no need to pay for another test. However, this does not happen often and there is no need to worry. To date, there has not been a case where a customer could not be tested for this reason. You can always call our line, we try to be helpful, or you can visit our workplace in Bratislava on Teslova Street, where we are ready to help you with the collection. (orders on tel. 0918 621 847)

In exceptional cases, when it is not possible to get enough blood into the microtube the first time, while both enclosed lancets have already been used, it is necessary to request replacement lancets, or also a microscope by phone. Make sure your hands are warm and that you have massaged your finger before collecting the blood sample. Drink at least 1/3 liter of liquid 15-30 minutes before taking it. Use the third or fourth finger.

It is not necessary to be on an empty stomach before taking it. You can make a withdrawal at any time of the day.

Some people find that obtaining a blood sample is not easy for them. In this case, ask a close person to help you with the procedure. Alternatively, you can visit our workplace in Bratislava on Teslova street, where we are ready to help you with the collection. (orders on tel. 0918 621 847)

The rule is that the child should no longer be breastfed. He should already be eating solid food. Children from 2 years of age are usually tested. In exceptional cases, after consultation with a doctor and assuming that the problem is caused by food intolerance, it is possible to start testing earlier.

It is possible that the level of antibodies will be significantly reduced if you have completely avoided a certain food and therefore it will be very likely that a food intolerance test will not detect the presence of antibodies. If you want to test whether you can tolerate the given food now and if you can deal with any symptoms that may appear, before you decide to repeat the test, try to include a portion of a specific food in your diet every day for 5-7 days. However, if you know that a given food is causing you unpleasant symptoms, do not include the food again in your eating plan.

Yes, several studies have demonstrated the involvement of IgG antibodies in the development of food intolerance and chronic diseases such as eczema, arthritis, or irritable bowel syndrome. An independent audit conducted in 1998 examined the reduction of symptoms in more than 2,000 people who underwent an elimination diet based on an IgG test. The audit demonstrated that more than 70% of patients had a significant reduction in symptoms after eliminating foods with high levels of IgG antibodies in the diet.

IgG means immunoglobulin G. Immunoglobulins are antibodies that are created as a reaction of the immune system to foreign substances that enter our body. There are several different types of immunoglobulins, the best known are IgA, IgE, IgG, IgM.

An antibody is created by the human immune system when a foreign substance (such as a virus, bacterium or toxin) enters the body. The body starts to produce special white blood cells called B-Lymphocytes to protect against such foreign substances. IgE antibodies are responsible for a true allergic reaction. IgG antibodies are a type of antibodies that can be identified precisely with our food intolerance tests. Several studies have shown that if we exclude from the menu foods in which a high level of IgG has been detected, this has a beneficial effect on reducing the symptoms of food intolerance.

ATTENTION food intolerance is not a weaker allergy. Other antibodies are responsible for it. If you have a positive allergy test result from your doctor, it does not mean that you automatically have an intolerance. This fact is important to realize. true allergies have other accompanying signs, they manifest in a different way.

In general, food is broken down during digestion into, for example, amino acids, glycerides, etc. These harmlessly pass through the intestines into the bloodstream. Nevertheless, small parts of them are sometimes or partially digested or undigested food proteins able to pass through the intestinal wall into the bloodstream, where the immune system identifies them as 'foreign'. The immune system responds by making antibodies (IgG). In some patients, inflammation or irritation of the mucosa will allow digested food to pass into the bloodstream. This condition can also be called "leaky gut syndrome". Such patients usually have high levels of antibodies against many foods.

It is possible that foods causing strong reactions are recognizable in the test, although we have not eaten them for years, so do not cross them with other members of the same category. Also, some antigens in food are less able to initiate an immune response than others, with the result that the production of antibodies to them does not start as quickly.

IgG-based food intolerance is caused by proteins and the antibody response to them. Sugar and alcohol are not proteins.

Antibody levels may remain detectable for several years after exposure. Due to the fact that some foods such as wheat, corn, and dairy products are widely used as food additives or processed in cosmetics, IgG levels persist in some individuals even when they mistakenly assumed that they had completely eliminated these foods from their diet.

The cause may be: a) you ate food 'X' in other meals without knowing it, or b) you ate foods from the same food group and this caused you to produce antibodies; c) antibodies supported by another food group 'cross-reacted' with food 'X'.

It could happen, but it is advisable to visit one of our cooperating advisors, who will determine this for you in more detail.

Not. Ask one of our Associate Advisors which food is in the same food group as food X and which could be causing the production of antibodies. He can determine that other foods from this food group should also be excluded from the diet.

Yes, some people have really high levels of IgG to certain foods but don't show symptoms. This is due to their immune system being extremely efficient at clearing antigen-antibody complexes before they get a chance to lodge in the body and cause a problem.

A study of infants with milk intolerance demonstrated accompanying immune complexes appearing in the serum just a few hours after consumption of cow's milk.

It is a condition where, due to the inferiority of the intestinal mucosa, there are large gaps between the cells of the intestinal wall, which causes large amounts of only partially digested food to enter the blood. Symptoms are varied: abdominal pain, heartburn, insomnia, swelling, anxiety, gluten intolerance, malnutrition, muscle cramps and pain, poor performance, food allergies.

No, because a reaction to one or only a few foods usually indicates a problem with the particular food being tested. The main sign of leaky gut is a positive reaction to a variety of tested foods.


There are two main factors that control the development of food intolerance based on the formation of IgG antibodies. The amount of a certain food in the diet and its ability to support the formation of antibodies. Foods consumed in large quantities are often associated with antibody production, immune complexes and symptoms. Some foods are more 'immunogenic' than others, i.e. are more capable of inducing the production of antibodies.

Diet composition and food particle size. Mineral substances also require the transport of molecules, and this is mostly a problem for people with this disorder. This can lead to significant mineral depletion in these individuals.

When a food causes the body to start producing high levels of IgG antibodies, these antibodies then bind to proteins and form 'immuno-complexes (clusters)'. These are usually secreted by other cells in the immune system. However, when the immune system is overloaded, these insoluble molecules are deposited in various parts of the body, such as head, lung tissue, gastrointestinal tract, skin and joints, where symptoms such as e.g. headaches, asthma, irritable bowel syndrome, eczema, rashes, arthritis, etc.

Intestinal biopsies of the study demonstrated the presence of cow's milk immune complexes in patients with colitis. Other studies have demonstrated the localization of human IgG and milk proteins in a sample of lung tissue taken from infants with pulmonary hemosiderin.

Lactose intolerance has a different mechanism than milk intolerance in our tests. Lactose is milk sugar and its intolerance is caused by enzyme deficiency. We test the formation of IgG antibodies to milk proteins. If you suffer from lactose intolerance, it does not mean that you also suffer from casein - milk protein intolerance.

Our tests are based on real testing of IgG antibodies from capillary blood. This is an exact result based on many years of research by doctors. After comparison, the IgG antibody test results did not completely match the bioresonance measurements.
