The whole process was very easy to follow. The facility I selected for my blood test was closed. The clinicians comment was extremely detailed but easy to follow. I had very constructive feedback and recommendations.

I do not like the lack of options to export my blood tests and provide them to my doctor. I read that there is a pdf version that I can download ONE TIME ... But I cannot find it. Several places in the results is says to discuss with my doctor.... but you dont make it very easy to do that. NO.. not happy.

I felt disappointed by my overall experience with Function. First, by the time I had already paid the money for lab work, Function informed me that they only take blood samples at specific labs in certain cities. The closest lab to me was a 3 1/2 hour drive away. Not knowing this information prior to purchasing OR having any flexibility on the clan companies with whom Function would work was frustrating and disappointing. Additionally, the communication interface with Function seemed unnecessarily complicated. I was receiving emails, text messages, and messages on my portal. When I did have a question, I just wanted to talk with a person. That proved challenging. I had to go through rounds of back and forth with a AI chat bot Finally, some of the automated communication I received from the company was unclear. The responses were general and vague. It took a The responses were general and vague. It took a fair bit of time to navigate the website, the chat bots, and actually get an answer to my questions. Overall, the experience seemed to be more of a hassle than I had anticipated. It seemed like maybe I should have just gone through my primary care doctor for labs. I will say, my experience was not all negative. What I DID like about working with Function was that the report I received about the specifics of my bloodwork was clear and informative. I hope this is helpful to other people who are considering working with Function
