The establishment of reference intervals for biomarkers in healthy populations relies on large-scale, standardized cohort data. However, current baseline data for hematology, liver and kidney function, and multi-omics (genomics, transcriptomics, proteomics, and metabolomics) in Chinese healthy populations are constrained by significant regional disparities and insufficient sample sizes, limiting the development of early disease screening markers. To address these challenges, this study aims to: (1) establish a comprehensive database for hematology and liver/kidney function indicators; (2) construct a multi-omics database using blood and sputum samples; and (3) explore the correlations among multi-omics indicators and their associations with demographic characteristics.
