Dishonest in several ways - run away
Everything is with AI. There are so many errors. They charge hundreds of dollars extra for NY and NJ tests. They have a glitch on the website where if you do an add on they make you go on two separate appointments. Now they are reneging on the 2 tests that were promoted. That is right. They now say 'only one time getting bloodwork' - as if it is a perk, but the high price was always justified by the double test. I am entangled with them now and it is a nightmare. Use any other service unless you want to join me in this ai mismanaged mess.

Hi David, we apologize for the frustration this has caused. Our team has let us know they have been in touch to resolve your issue, and have offered phone support if you are open to a call. Please reply there if we can assist you further. As a note, Function membership includes the following: ∙ The Annual Test: 100+ advanced lab tests every year — this first round of testing is typically split across 1–2 visits within a 10-day window. The visit count can vary depending on your testing profile and whether any add-on tests are included. ∙ The Mid-Year Test: retests 60+ core lab tests from the Annual. Run 4-6 months after the first set of tests each year. ∙ Add-on test menu to re-test anytime (additional cost) NY and NJ have healthcare billing rules requiring an additional payment directly to the lab (e.g. Quest Diagnostics) via credit card during or shortly after your blood draw. To be clear, none of this fee goes to Function.
