Blood Testing Purchasing a blood test powered by Fuelary will help you and your coach identify what, if anything, is off in your body functions. Fuelary uses “Optimal Reference Ranges ” instead of standard ranges. Standard reference ranges are designed to identify and diagnose disease states only. The standard reference ranges were determined using a large number of seemingly healthy individuals but may have included individuals with health issues. The optimal reference range is also called the therapeutic target range and is a much more narrow range associated with minimal risk of developing disease or complications. To learn more about each test click on the “Intro” document and check out the example patient report. Ordering your blood test is simple! Input your personal information, select your test, and submit payment. Then get the information YOU need to improve your health and performance!
