Based on the current urgent need for an in vitro quantitative detection system for allergens in most hospitals in China, we introduced a novel allergen-specific immunoglobulin E detection system that employs a solid phase enzyme-linked immunoassay and evaluated its clinical performance. The system uses a special reaction component (innovative patents) to reduce the reaction time to 12 min, achieving point-of-care testing for allergy management, which is impressive compared to the 3-18 h testing time for all other systems. In addition, the AILEX system has excellent consistency with the ImmunoCAP reference method system; therefore, we recommend the introduction of the AILEX system for clinical auxiliary diagnosis in medical units.
