# Biomarker

## Intro

A **biomarker** displays an objective indicator of health captured during a Face Scan, such as heart rate or respiratory rate. If a measurement was performed on a previous day, the previous value will be shown in the footnote.

This component is essential for usecases where immediate, real-time feedback on specific health parameters is desired. It’s designed for quick, actionable insights. Integrate it within your platform to give users a clear, snapshot view of a particular aspect of their health.
