Biomarker identification

Definition

Biomarker identification refers to the process of discovering and validating biological markers that can indicate disease states or responses to treatment. These biomarkers can be proteins, genes, or other molecules that provide valuable information about the underlying biological processes. Identifying reliable biomarkers is crucial for understanding complex diseases and developing targeted therapies.
