Demographic variables, allergy history, foods involved, clinical manifestations, and diagnostic methods used were described.RESULTS: 253 oral food challenge tests were performed in 179 patients; 83% were children. The overall positivity rate was 15.4%, with the most frequent reactions to cow's milk (6.3%), egg (3.1%), legumes (1.5%), and fish (1.4%). Most reactions were mild, with a predominance of cutaneous and gastrointestinal symptoms. Only two cases of anaphylaxis were recorded (0.8%).CONCLUSION: This study provides clinical evidence of food allergy in Colombia, demonstrating an allergenicity profile distinct from that of other regions. The findings reinforce the need to standardize diagnostic criteria in Colombia and promote multicenter studies that define predictive thresholds adapted to local contexts.PMID:41913403 | DOI:10.29262/ram.v73i1.1573
