I've used Function for about a year now…
I've used Function for about a year now and it's been nice. I love the detailed bloodwork and going in for labs is quick and easy. It's particularly gratifying to be able to visualize the trends as they develop as you gain more results over time. They also give really nice, detailed descriptions about the biomarkers being tested. The clinician notes are a great, but basic informative resource. Their disclaimer is true, it's really not a replacement for a PCP. Sometimes I wish the notes didn't feel as "generic", or maybe it's an AI flavor I'm noticing - the notes SAY a lot, but when you boil it down you are still left wanting a little more substance or interpretation. Overall, as someone who is mostly healthy, I find the subscription is a great value - I particularly like that extended cholesterol biomarkers are included in the standard membership. Their add-on tests have also helped me realize that I've got several substantial food sensitivities I was not previously aware of. I joined when the annual membership was still like $600/year, so it's nice to see something has actually gotten more affordable. Lastly, I feel their tech support is mostly reliable. It's via chat/texting which works for our family. I'm dealing with one question this week though that has me slightly disappointed (bought a promo add-on test, still need to schedule it, but it's not showing anywhere in my portal even though the receipt of payment was emailed to me). Their chatbot said on July 1st that someone would respond to me via email within 24 hours, and it's now July 3rd with no answer yet - so, they do have small hiccups, but it's not enough for me to quit using their services.
