Biomarker epidemiology is a branch of epidemiology. A comparative newer advance in the field, biomarker epidemiology helps in trait analysis by identifying biomarkers in population based studies.[1] Biomarker epidemiology is undergoing rapid development and expansion and is becoming one of the most promising areas of environmental research.[2]
Biomarker epidemiology can be applied in several fields. One is genetic epidemiology, which conducts linkage analysis and family-based association studies, and is applied in gene discovery; molecular epidemiology, which researches to characterize gene-disease associations and gene-environment interactions using biomarkers, and is applied in gene characterization; and applied epidemiology/health services research, which studies to evaluate clinical validity and utility of genetic information in practice, and is applied in evaluation of health effects.[3]
