Background: The diagnosis of non-IgE mediated food allergy is done mainly by in vivo Oral Food Challenge (OFC) tests that depend on well-succeeded previous exclusion diets.
Objective: To evaluate the opportunity of the in vitro semi-quantitative research of specific precipitins to select food allergens to proceed with exclusion diets and further in vivo oral food challenge tests in food-allergic patients.
Methods: The tube titration of specific precipitins against food allergens in food allergic patients was compared with the in vivo oral food challenge tests performed after a well-succeeded exclusion diet. The probability of a positive or negative OFC was estimated according to the precipitin’s titrimetry.
Results: The correlation coefficient bet.. View more»
