    Common questions

    Function Health vs. ONE BioOS

    Is Function Health available as an employee benefit?

    Function Health is sold directly to individual consumers, not deployed by employers. ONE BioOS is built to be rolled out as a workforce benefit, with HR-level dashboards and per-employee guidance included.

    How is ONE BioOS different from a biomarker panel?

    A biomarker panel like Function Health's is a snapshot — accurate on the day you draw blood, then static until your next draw. ONE BioOS combines biomarkers with wearable and behavioral data through the OPL® Engine, so the picture keeps updating between draws instead of going stale.

    Can we offer both?

    Some organisations do — individual employees may already have a Function Health membership. ONE BioOS is designed to sit on top as the employer-side layer: workforce dashboards, continuous monitoring, and an OPL® score HR teams can act on.
