Refers to the genome-wide expression of all genes obtained from cells present in the blood. Transcriptome analysis of whole blood has the potential to revolutionize non-invasive disease diagnosis and identification by providing a comprehensive gene expression profile that reflects the physiological state of an organism.
Whole blood contains various cell types and diverse transcriptional states, making it a rich source of easily accessible gene expression data for analyzing physiological or pathological states in tissues that are difficult to access (Basu et al., 2021).
