In case of allergy, IgE-antibodies are found in the blood directed against food or other allergens in your environment, like house dust, mold or pollen. According regular medicine these allergies only occur in people that are genetically predisposed, called atopy. One quarter of the Dutch population has such a predisposition. In atopic patients, one or more of the following diseases or symptoms occur like atopic eczema, runny nose or a stuffy nose, conjunctivitis of the eye, hay fever or allergic asthma. Next to this, atopic people more often have allergic symptoms like rashes and hives due to certain drug use. They furthermore also react to dust, infections, natural phenomenons, weather influences, clothing etc.
The largest part (75%) of the population does not have this allergic aptitude. Food allergies and other allergies do however occur in this group as well. In these people antibodies of another type are raised like IgG or IgG4. In order to detect these antibodies, tests are developed by the KEAC laboratory. These tests have been used for more than 30 years in the meantime by patients in Europe and beyond, in scientific research and the test is sometimes reimbursed by the health insurance companies
