Need an IgG food sensitivity test  / food intolerance test?
We are the address!

A little background


IgG is a central antibody found in the blood serum. An antigen is a substance foreign to the body, which may stimulate the immune system to produce an antibody specifically adapted to it. There are reactions to food antigens that are mediated by IgG antibodies and these may arise with a delay of several hours or days from the moment the food is consumed. These reactions are called type 3 hypersensitivity, and because they are not immediate, there is a difficulty in diagnosing them, and in being able to link a symptom that was created as a result of a specific food that was eaten. 

Exposure to foods that increase the level of IgG antibodies trigger an inflammatory response in the body and prolonged exposure may produce chronic inflammatory processes. The typical symptoms of food reactions mediated by IgG antibodies include: digestive system problems (IBS-like), gas, constipation, diarrhea, abdominal swelling. Skin problems such as psoriasis, eczema. Migraines, headaches and sometimes even unexplained obesity and mood swings.

It is important to distinguish this allergy from an allergy that is a type 1 immune reaction. This is the classic and familiar food allergy.  It produces an immediate reaction (a few minutes) of histamine release mediated by IgE antibodies. Symptoms can be life-threatening and include an anaphylactic reaction, swelling of mucous tissues, itching and redness of the skin. It is important to note! An IgG test cannot diagnose a type 1 food allergy.

Blood test to detect IgG antibodies  

In a blood test to detect IgG antibodies, the presence of IgG antibodies in response to different types of foods is tested. These antibodies are identified by their ability to bind to specific proteins in the foods being tested. During the test, the concentration of antibodies present in your blood sample is measured for each specific food tested and the answers are divided into   3 categories:

  1. No sensitivity

  2. high sensitivity

  3. Very high sensitivity

The test is done using a method called ELiSA (Enzyme Linked Immunosorbent Assay).

Each patient who performs a test of 260 types of foods receives a consultation from a clinical dietitian for about 45 minutes.

In addition, you get the option of connecting to a personalized application according to the results of blood tests.


Do not perform a food intolerance test in case of:

  1. Beach sickness or acute infection in the body.

  2. Hypoglobulinemia HYPOGLUBOLINEMIA - total IgG antibodies below the normal range.

  3. The presence of a monoclonal protein in the blood.

Taking medication while performing the test such as antihistamines, steroids and antibiotics and in particular drugs that suppress the immune system may affect the results of the test.

In case of doubt about the effect of the immunosuppressive drug, a total IgG test (a routine laboratory test) can be performed before the food intolerance test. If the IgG level is within the normal range, the drug treatment does not affect the level of IgG antibodies in the blood, and the food intolerance test can be performed.


It is important to note !!

The test only checks foods that were consumed at least six months before the test, for example if you haven't eaten dairy products in the last six months, the test will not show a sensitivity to dairy products.

Do not stop using the medicine without a doctor's approval.

Insurance reimbursement- In principle, anyone can check with their insurance agent or the company they are insured with regarding reimbursement. There are companies that return between 60-80% (it changes from time to time) according to the policy of the insurance company.

This can be found out at the claims center of the insurance company. 
All tests fall under the category of ambulatory tests - diagnostic tests, of course it is mandatory to attach a referral from a doctor.
