Review summary

Created with AI, based on recent reviews

Looking at 1,150 reviews, reviewers overwhelmingly had a great experience with this company. Customers consistently praise the detailed and clear information provided, especially the thorough explanations for each test marker and the comprehensive summary clinical notes. Many appreciate the ease of the process, from setting up tests to receiving results, and find the product offers valuable insights into their health at a reasonable price. The ability to track numerous biomarkers and receive recommendations for supplements and diets is also highly valued, empowering users to take charge of their health. However, some people mentioned dissatisfaction with the lack of direct interaction with medical professionals to interpret results or guide treatment, feeling the experience was impersonal and lacking follow-up. There were also concerns about the cost of additional tests and the amount of blood drawn, with a few reporting issues with partner services and customer support responsiveness.

The whole service is amazing

The whole service is amazing. I love the app and was glued to every update from my bloodwork. I am a healthy 55 year old woman, but I found some concerning inflammation and other lipids that are prompting me to get a heart CT scan. The clinical notes were incredibly detailed and helpful.

Comprehensive Health Information

I believe Function Health offers a great service, drawing and processing bloodwork and providing results as well as clinician notes. I found it to be comprehensive and informative. I would have given 5 stars except for the automatic renewal. Upon cancelling the renewal I received a partial refund. While the service is valuable, it costs an additional $500 annually since I live in New York.

I was impressed by what was involved with the entire process. I was looking for comprehensive blood work, but was happy with the comprehensive intake form & medical history process.

Results came back quickly

Results came back quickly. Good detailed information behind each one.

The only thing that I was unclear about were the genetic/DNA results that did not have a range and it wasn’t cleared to me if the results were positive or negative, good or bad.
