Objective: To characterize the prevalence of specific allergic conditions, identify the most clinically relevant allergens, and examine polysensitization patterns in a pediatric population from Cartagena, Colombia. Design, setting, and patients: Cross-sectional study conducted between December 2024 and March 2025 at a Respiratory and Allergy Clinic, Colombia, including 122 consecutive pediatric patients aged 3–17 years with clinical suspicion of allergic disease.
