I’m so glad my friend told me about Function Health. It is a great experience. Most people don’t have the chance to get a complete blood test done, at least not covered by insurance, unless you are truly sick. With Function Health’s affordable price, I am happy to learn about the whole picture of my health, especially the potential problems. For each result, it is explained in details by medical experts. The action plan is also extremely valuable. I believe my health will improve by closely following it.

Such a great experience The process was very easy and quick. I made my appt. and i was waiting under 5 minutes and it only took less then 10 minutes to complete. I've already had my daughter sign up for her blood work. My results were easy to understand and now I know what I need to do to improve my next tests.

Easy instructions for the bloodwork. Lots of results with written explanations- follow up bloodwork also easy with the same written explanations which helps to see if you’re staying on track with good results or need to adjust some Life style decisions :)
