Frequently asked questions

Who should I gift a Function membership to?

Anyone who wants to take control of their health—or needs a reason to start.

Give it to:

  • Your partner who always says "I'm fine"
  • An aging parent who wants insight into their changing body
  • Your adult kids, as an investment into their future
  • A caregiver who struggles to put themselves first
  • A friend who has just started prioritizing their health A Function membership is more than thoughtful. It can be a powerful wake-up call, starting point, or vote of confidence for someone you love.
Why are we called "Function"?

Your body, mind, and healthcare system should function. But corrupted food systems, chronic stress, and outdated practices can push you toward dysfunction. We exist to change that. We give you insights across your body—heart, hormones, thyroid, nutrients, toxins, inflammation, and more—so you can stay in control.

Can an employer pay for employees’ Function memberships?

Yes. Employers can fully or partially fund Function memberships as an employee wellness benefit.

How does Function work for employees across different locations?

Function is available in most states through Quest, allowing employees to schedule tests where it’s most convenient.

What is a biomarker?

Biomarkers are measurable signals in your body—like a hormone, protein, or vital sign—that can reflect shifts in your health even before symptoms show up. For example, elevated Apolipoprotein B levels can be linked to increased heart disease risk. Tracking biomarkers helps you spot changes early, so you can take action sooner.

What kind of reporting can we expect?

You’ll get detailed reports* on enrollment, engagement, test completion, biomarker trends, and overall population health, so you can track impact over time. *This data is aggregated and de-identified for privacy.
