What function doesn’t tell you upfront…
What function doesn’t tell you upfront is that their parameters for what is considered in range or out of range bloodwork are much tighter than clinical standards. I spent many months thinking that I had a lot of unhealthy bio markers and scrutinized my entire lifestyle, which is actually very healthy, to the point of daily anxiety. Come to find out most of these markers were actually clinically in range. I think Function is a great app, but there needs to be more transparency.
