Lab work is a cornerstone of functional medicine, but many patients are told their results are “normal” even when symptoms persist. In this episode, Brigitte Sager explains how functional medicine interprets labs differently by looking for optimal ranges and early patterns that can reveal insulin resistance, inflammation, thyroid conversion issues, and more before a diagnosis is made. She also clarifies what’s within an RN’s scope of practice when reviewing labs, and shares practical options for helping clients access testing through prior labs, provider collaboration, and lab-ordering platforms.
