Easy to book blood tests and getting quick results was helpful. I wish I had a doctor who would prescribe supplements and medication ms as needed.

Amy M.
Highly Recommended. I have used Function's bi-annual blood test workup for two years and find it an excellent service. I get a full panel with explanations about what each test is for, and if my score is above or below acceptable range they provide great information about why it matters, and suggestions for how to address it. Far more detailed information than I get from my MD.

Laurie, Penny’s M.
So far it has gone well. I will know today how easy it is to get the results to my doctor and hopefully they will accept it since “they” didn’t order them. I may expand Function services depending on how compliant my doctor is.
