[Precision medicine in the diagnosis of allergic airway diseases: current applications and future directions].

The rapid advancement of precision medicine is shifting the clinical diagnosis of allergic airway diseases away from traditional models that rely solely on symptoms and phenotypes, and toward individualized, precision-based diagnoses that are molecularly driven. This review describes the role of established biomarker systems, such as eosinophil count, fractional exhaled nitric oxide, and specific immunoglobulin E, in inflammatory endotyping and targeted therapy. Furthermore, the integration of multi-omics technologies and artificial intelligence algorithms facilitates the elucidation of disease heterogeneity and molecular mechanisms, thereby advancing precision stratification. The proposal of this article is an integrated precision diagnostic framework combining multi-dimensional data integration, dynamic monitoring, and intelligent analysis. By establishing a systematic biomarker evaluation pathway, this framework aims to promote the application of real-time monitoring technologies and AI-assisted decision-making, thereby providing a reference for the optimization and evolution of next-generation precision diagnostic systems.
