How to prepare for Cortisol Genetik

Preparing for a genetic test for cortisol (e.g., genes NR3C1, FKBP5, CRHR1) is straightforward because DNA is stable. No special diet or fasting is required. If the test uses a saliva sample, avoid eating, drinking, or brushing teeth for 30 minutes before collection to ensure sample quality. Crucially, such tests analyze genetic predispositions, not current cortisol levels. For actual cortisol measurement (blood or saliva day profile), different protocols apply. Evidence linking these variants to actionable outcomes is weak – lifestyle and stress management are far more influential. Always have results interpreted by a clinician.
