It was quick and efficient. I hardly had to leave the house. The eliminate list has been very accurate.

Always had good cholesterol numbers at my doctor’s office because they were within the normal ranges. Function identified that I have a high Apo(b) and Lipoprotein(a) which does not make me normal. I will be discussing the findings at my next doctor’s appointment to maybe be more aggressive in lowering my LDL.

the site is very easy to use. The chat function is amazing! I get an answer each and every time and very quickly.

They were helpful to remind us of our follow up tests. I had some trouble sorting out the difference between included tests and Add-on elective tests. The AI assistant was responsive, and probably as good as any I've come across

Great value for all the tests that are performed. The clinicians notes are very helpful.

I love Function Health. Having extra bloodwork that most doctors do not do is wonderful!!

You guys are quick to answer my questions, but more importantly is there were more blood markers than I had anticipated, which narrowed down my health issues - huge win! Although it did take a while to have all of my results available and the doctor notes be complete, that's a nice to have, not a need to have. I started addressing the areas in question and I'm already feeling better, definitely will be referring!
