You may not recognize some of the names of these tests, as many are at the leading-edge of medicine and have not yet been widely adopted by traditional primary care doctors.
Yes. You will need to show your ID during lab visits and it must be an exact match in order to be tested.
Function is FSA/HSA eligible. Members can expect to receive an itemized receipt via e-mail within one business day of scheduling lab testing. The receipt will include a cost breakdown, date of payment and service, and the ordering clinician. If you have not received an itemized receipt after one business day of scheduling your lab visits, please email hello@functionhealth.com and we will make sure one is sent to you. Function does not provide a Tax ID number, medical diagnosis, or diagnostic codes. Reimbursement is not guaranteed. Please contact your FSA/HSA provider in advance to confirm terms of reimbursement.
No, Function does not replace your doctor or concierge care. Instead, it makes you a more powerful patient. Membership includes 100+ lab tests annually and provides detailed insights from the world's top doctors specific to each result. Additionally, you will receive an opinion from a physician that reviews every set of lab tests results, and that can be shared with your doctor.
Bringing a history of lab test results to your next doctor visit may reduce the need for follow-up tests and enable a more productive appointment. Function is designed to make the doctor's time more effective and empower you to be your own advocate.
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.
Beta means that Function is not yet fully developed and there will be rapid changes with occasional bugs. Patience is required.

Leading doctors across specialties, including Function's co-founder and Chief Medical Officer Mark Hyman M.D., have spent decades determining the correct comprehensive set of lab tests that should ideally be routinely done. Function reflects this deep cross-specialty analysis across cardiology, oncology, endocrinology, immunology, nephrology and more.*
No. Function is not an insurance plan nor do we accept insurance. It is fully out-of-pocket, which in this case means all prices are transparent with no hidden fees.

Completely different. Most lab tests Function gives you access to will look at parts of your health that are ever-changing and improvable, unlike your genetics which are fixed. The few genetic tests Function gives you access to are critical for understanding your risk for conditions like heart disease and Alzheimer’s. Function’s list of tests here.

As promising new diagnostics are developed, they will be made available to Function members if our medical team believes they are both valid and important for revealing the deepest understanding of your health.
Right now. Although Function will immediately help you understand what’s actually happening inside your body, spotting negative and positive trends requires time. The sooner you start, the more you know how to take control of your health.

Function is for anyone over 18 years old. Function helps you understand your health today and how it changes over time. The earlier you establish a baseline with a single set of test results, the easier it will be to know your body’s trends and ways to help take control of your future.
Most of the time, insurance will negotiate with a lab and pay a reduced amount off a higher price. The problem is, if insurance is not paying or negotiating the price downward, people are usually stuck with the high price tags on testing. For instance, the combined tests included with Function memberships could cost more than $15,000 elsewhere. This is unlikely to change without companies like Function paving a new path.
The traditional insurance route typically requires a specific symptom or condition to warrant comprehensive testing. (We find it backward to require the existence of a condition to test for that same condition.)
To get all the tests included in your Function membership, you would need to work with a doctor willing to request these 100+ tests. Doctors rarely have the time needed to review this many tests, let alone to understand and explain your results to you. They also want to avoid creating financial burdens on their patients who may be billed for any advanced lab tests. You would also likely miss out on insights from the world’s top doctors based on your specific results.
Comprehensive testing has historically presented major hurdles to patients, including the need to decipher hard-to-read PDF's, google searching what results mean, adding numbers to spreadsheets to catch trends, and getting tests without knowing the cost until the bill arrives. Function organizes all of this and delivers so much more—including transparent pricing and insights from world-renowned doctors based on your results.
Terms vary from provider to provider, so we recommend contacting your insurance company in advance to determine if your purchase qualifies. Please note: Function can provide detailed receipts that include a breakdown of costs, date of payment, date of service, and ordering clinician. Function cannot provide a Tax ID number, a medical diagnosis, or diagnostic codes.
