We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
Always review your personal lab results with a licensed clinician, or track your lab history and health goals in Aumnivida.
