Methods In this study 25 celiac patients with a mean age of 30.8 ± 13.6 years in Ilam province western Iran were recruited. Approximately 6 ml blood sample was taken from each participant. Food allergy was assessed by EUROIMMUN kit and analyzed by EURO line Scan software (Es). According to Es, patients are categorized into 5 categories including 0 (no specific antibody), 1 (very weak antibodies with no clinical symptoms), 2 (a weak antibody detection/AD and often existing sensitization), 3 (a definite AD), 4 (a strong AD) and 5 (very high antibody titer). The current kit evaluates different food allergy such as fruits, egg, peanut, potato, meat, shellfish, rice and milk.
