What does a Function membership include?
For $499 per year, a Function membership gives you:

• 100+ lab tests at the start of each year—no hidden costs, no insurance required.
• 60+ follow-up tests at 3–6 months to track changes.
• Insights from top doctors based on your results.
• A written clinician summary to help you understand your data.
• Access to re-test at transparent prices when needed.
• Option to purchase additional tests, including Lyme, STDs, and allergies.
• Access to groundbreaking tests, like the Galleri Multi-Cancer Early Detection test.
  

Function is for anyone 18 and older. The sooner you establish a baseline, the better—you’ll see where you stand today and track changes over time. Understanding your body’s trends gives you the power to make informed decisions about your future.

Function takes privacy extremely seriously. We use a range of the latest technical security tools and administrative measures to safeguard your data against unauthorized access or disclosure. Note that Function cannot secure personal data that you release on your own or that you request us to release, so we recommend carefully considering with whom you choose to share this data.

Function is 100% insurance-free. No deductibles. No co-pays. No surprise bills. We are committed to transparent prices and you knowing exactly what you pay for. Function does not accept insurance; however, it is FSA/HSA eligible. Function provides you with an itemized receipt for submitting to an FSA/HSA plan.
