Digital biomarkers are used to collect the data about disease management through digital health technologies to predict health-related outcomes. As the role of biosensors, wearables and mobile health in modern healthcare evolves, the potential of digital biomarkers to continually monitor patient health, rapidly diagnose disease, and accurately predict outcomes becomes increasingly apparent. Physiological data may now be collected via digital devices such as portables, wearables, and implantables. It includes electronic medical records such as patient history, medical imaging, genetics, etc. as well as patient-generated data. Digital Biomarkers in drug development.
