Thank you for sharing your feedback. Function is designed to go far beyond a typical annual lab panel. A standard yearly visit usually includes about 19 tests, while Function provides over 100+ tests across key areas such as heart, thyroid, hormones, nutrients, immunity, autoimmunity, and more. Along with this expanded testing, every member receives a detailed clinician summary reviewing their latest results, plus personalized insights from leading doctors to help you better understand your health over time. If you’re open to sharing more, our team would be happy to help. Please reach out at [email protected]

I feel like I have a much better understanding of what is happening in my body. I have things to work on that I would have never known about if it weren't for Function.

Invaluable information, with quick and knowledgeable responses to my questions.

if you have enough money to burn or are easily swayed by friends, then this is the perfect vanity service for you! tbh you’ll get most of these diagnostics from your GP; this extensive blood work is not worth the time and money. also, they fail to note that in NY state there are additional blood drawing fees. we love some expected fees!
Response from Function HealthOct 8, 2025
We’re sorry we haven’t lived up to expectations, Cody. In New York and New Jersey, state billing rules require an additional fee paid directly to the lab—none of which goes to Function. Everywhere else, your $499 membership fully covers 100+ lab tests. Even with the state fee, the total cost remains well below what these labs typically cost through a GP. We’d love the chance to continue the conversation. Please reach out to us at [email protected] so we can provide additional support.

Exceptional customer service. Phenomenal blood work. I learned more from their test results than through any doctor.

I love how informative all the lab results were. My most favorite was guidance on what foods to enjoy and what foods to avoid. If you could add recipes to the app that matches our food recommendations that would be awesome.
