Getting lab work done went very well, and returning results to me was good but poor on communicating with me, especially in person as I have other health issues not directly dealt with

The results of the bloodwork were informative. Each result came with an explanation and recommendations what one can do to reverse bad numbers. I am waiting three months and will have my second blood work done for new results. I love this bc you can start working on reversing anything that is heading in a bad direction.

I like the affordability and comprehensive tests, but I wish there was an option to consult with a clinician post test results . While the AI-generated result interpretation is helpful, it's not specific enough. For example, supplements were recommended, but not the dosage, timing, frequency, etc. When I messaged Function regarding followup options , I was told to consult my Primary care physician. Well, my PCP was not trained in nutrition or supplements so she had no idea what to recommend. Even if Function had a list of clinician referrals in my area would be helpful. While having the raw data is a starting point, the way ahead isn't provided. Researching on line is too generalized. Ways2Well, for example, has an option to consult with a human post results which is terrific. While relatively happy with Function, I will probably switch to W2W for the clinician option so I have a Plan Of Action
