Results support clinician interpretation and are not a stand-alone diagnosis. Each badge shows the panel a marker belongs to — the Hormone and Metabolic kits are collected at home with a painless upper-arm device; the deepest markers run on the in-lab Protocol Panel. Not all markers are available in every state.
