**Abstract**

Asthma was a chronic inflammatory airway disease which characterized by complex pathogenesis, various clinical manifestations and severity. Blood biomarkers have been used to evaluate the severity of the disease, predict the efficacy and prognosis. Currently, some incredible progress in most of the research on biomarkers for asthma have achieved, including cell, antibodies, cytokines, chemokines, proteins and noncoding RNAs. We reviewed the application of these biomarkers in diagnosis, treatment, prognosis monitoring and phenotypic identification of asthma, in order to improve clinicians' understanding of asthma biomarkers.
