What Is Functional Lab Testing And Which Test Is Best?

Lab tests are used to gather data about a person’s health to determine a disease or treatment plan. There are differences between functional lab tests and conventional lab tests in how they’re used to evaluate health and determine a course of action. With functional lab tests, practitioners can dig deeper into what’s happening in the whole body and why it’s happening, allowing them to catch early signs of disease years before conventional lab tests would ever pick up. This is partly due to the way standard medical ranges are determined, making it easy to fall into the “normal” range even when you feel awful.
