I recommend that if you are struggling to get a diagnosis and cannot get to the root of your health issues Function Health is a great start to taking control of your own health. This simple tool can provide insight and actual labs that can assist your physician and you in a proper diagnosis or treatment plan. Without the right diagnosis many insurance companies will refuse to cover these labs, and many doctors will not even see a need to order them. When you get these done with Function Health you do not need their permission to do so.
