The study is aimed at improving the diagnosis of food allergy, specifically allergy to commonly consumed legumes such as peas, lentils, chickpeas or green beans. Patients suspected of allergy to these legumes will be examined using traditional methods of IgE-mediated allergy diagnosing (skin prick test, testing for specific IgE antibodies against food extract), but also by testing for specific IgE antibodies against relevant allergenic molecules of these legumes. The results of performed tests will be compared with the result of the oral food challenge, which is considered to be the gold standard of food allergy diagnosis.
