The only “complaint” is that there does not seem to be a seamless way to get results to my PCP. On the other hand, being able to connect to ChatGPT was phenomenal, the most in-depth “doctor” visit I’ve ever had. Extremely satisfied.

The website interface is nice until you have a problem. My wife needed to reset her password and reschedule an appointment. It seemed simple enough, click on the rest password link received via email, enter the new password twice and click "Continue". Every time she did that a message would come up saying "The password reset link is no longer valid. Please request another one." We tried resetting her password about 10 time on her phone, my computer and it wouldn't work. Then we tried chatting with their AI chatbot which also didn't work. The bot was going to transfer us to a "Live Agent" and asked for contact information. I typed it in and waited and waited an waited and no one showed up. As a result I started typing in questions and then all of a sudden all that I had typed disappeared and I received the message to type in my contact information again. Overall the scheduling, blood work, and lab results were okay, but not being able to get help when you need it isn't acceptable. We'll be looking at other solutions in the future.

I like the wide range of panel testing. However, each resulting Cinician Notes have become shorter and less informative than the previous… like a physician too overwhelmed with readings and just trying to get through the stack.

Scheduling my labs couldn’t be more simpler. The Function Health website is easy to navigate, so I can quickly select a Quest Labs location near me through the Function Health website and schedule my appointment. It is also incredibly easy to schedule additional test at a very reasonable cost. There are some markers that I may want checked more frequently, and Function Health gives me that opportunity without having to request it from my Primary Care Physician. This is one of the best investments you can make in yourself because you can start to take charge and monitor your own health and identify deficiencies or issues before they create larger and more costly health concerns. The Clinician Notes provided at the conclusion of your labs are also very thorough and give great insight into what your results really mean for you.
