In case of allergy, IgE-antibodies are found in the blood against food or other environmental allergens, such as house dust, mould or pollen. According to conventional medicine these allergies occur only in people that are genetically predisposed, a condition called atopy. One quarter of the Dutch population has a predisposition to atopic condition. In atopic patients, one or more of the following diseases or symptoms occur: atopic eczema, runny or stuffy nose, conjunctivitis, hay fever or allergic asthma. In addition, atopic people are more likely to have allergic symptoms such as rashes and hives following the use of certain drug use. Furthermore, they may also react to infections, dust, clothing, weather influences and other natural phenomena.
The majority (75%) of the population does not have this allergic aptitude. However, food and other allergies can also occur in this group. In these people, antibodies of another type may be raised e.g. IgG or IgA. In order to detect these antibodies, tests have been developed by the KEAC laboratory. These tests have been used for more than thirty years in scientific research and by patients in Europe and beyond, and are sometimes reimbursed by health insurance companies
