What This Converter Does And Does Not Do
It does not diagnose
A converted value is still only one lab value. Guidelines discuss symptoms, repeat morning testing, reliable assays, and clinical context.
It does not set targets
Do not use this tool to choose a dose, supplement, target number, or treatment plan. That requires clinician evaluation.
