You can live
100 healthy years.

It’s time you own your health.

Put yourself on a new path with testing for 100+ lab tests and followup testing for 60+ lab tests 6 months later. With detailed clinician notes, your results are more than just data — they’re clarity. So you can know where you stand and decide where you’re going.

Due to state regulations, individuals testing in New York or New Jersey will be charged additional fees of ~$250 per year; Invited will reimburse you. As part of sign-up, you will be required to input your credit card information for optional add-on testing and renewal, and provide consent for Function to share participation data.

As someone navigating an autoimmune condition, it's been such a relief to finally have a clear, visual way to track what’s going on in my body—and actually understand it.

Early detection has given me this amazing gift of extra years, probably extra decades, with my family.
