[The developing risks of the allergic child].

6% of infants are allergic to egg. 50% of them are at risk of becoming sensitive to pneumoallergens and of whom 50% develop asthma. These evolutionary risks which are the allergy "course" of the child may be avoided by a precise interrogation which is orientated towards detection by in vitro tests of F x 5 for foods and Phadiatop for pneumoallergens. The responsible allergens may themselves be shown by skin tests, measurement of specific IgE by CAP-RAST made by UNICAP.
