Skin tests represent a major tool in the diagnosis of IgE mediated- @entity566 . The main indication is the measure of atopy during infancy and early childhood, as a predictive factor of the development of @entity565 . When @entity483 is present, skin testing can provide a diagnosis of @entity5419 . Skin tests are easily done, without absolute contraindications. The epidemiological knowledge helps to choose the allergens to test. The skin-prick test method is well standardized and must be rigorous because of the hyporeactivity of the @entity1 skin. Results are always confounded with positive and negative control solutions. The interpretation of pricks tests must be careful, standing out a clinical @entity566 (when clinical allergic symptoms are presents) from a sensitization (atopy). The predictive value of a positive skin test is discussed: predisposition to @entity565 , association with severe @entity565 , predisposition to acute @entity5924 during an @entity1576 . A positive skin test to food allergen would predict a later pneumallergen sensitization.
