Nice service and app. The tests were smooth through Quest Labs, and the results hit the app fast. Thank you

Great service. Will not share clinicial notes easily. According to their own AI: "So the short version: the notes are there to help explain your results in context, but Function’s current sharing/export flow is limited — and yes, that can make the process more cumbersome than it should be."

This goes far beyond the typical lab work you get at your annual physical. I was astounded by all the data. The report was very comprehensive and will be used as a tool in my wellness journey.

I've been using FH for a couple of years now. Experience with the testing procedure has been excellent and I like the results and how it's layed out. However, their customer service is horrible. Any questions, queries are handled by AI. If you need to escalate to a live "specialist", the response won;t come for at least one business day, which is unacceptable if you're trying to get answers during regular business hours. If you press for answers, the responses are all mechanical - there is no doctor or healthcare provider responding. Answers could actually be coming from a call center in India. I'm researching now alternatives as FH's service is subpar at best.

I am unable to link the results to my primary care's EMR. I am unable to view the results on Quest's website. There should be the name of the provider who reviewed my results on the results. Was it all done by AI or did an actual provider review the results. It does not seen to consider past medical history in results.
