Abstract

Background Serum albumin (Alb) is an essential indicator of human physiological function, which can reflect the functionality of multiple organs, including the liver and kidneys. Presently, numerous studies have indicated that levels of blood albumin serve as important biomarkers for a range of respiratory illnesses. These findings can better guide clinical practice and disease prevention. However, there have been few investigations into the correlation between serum albumin and asthma. Therefore, this study aims to explore the relationship between serum albumin and the onset of asthma.
