wie kann ich cortisol messen — what does this mean exactly?

Cortisol is typically measured in blood, saliva, urine, or hair. Blood and saliva tests capture free, biologically active cortisol, while urine and hair tests reflect cumulative exposure over time. Measurement methods include immunoassays (e.g., ELISA) or liquid chromatography–mass spectrometry (LC-MS/MS). Timing is critical: cortisol follows a circadian rhythm, peaking in the morning and dropping at night. A single value without context (stress, sleep, medications) is of limited use. MyBody-X offers hormone tests that include cortisol measurement in blood or saliva – but as a wellness tool, not for medical diagnosis. The evidence for such home tests is weak; clinical relevance requires a doctor’s interpretation. Caution: low cortisol may indicate adrenal insufficiency, high levels may suggest Cushing’s syndrome – both need medical workup. Without professional guidance, misinterpretation is common. The question 'what does this mean exactly?' targets interpretation: an elevated level alone does not indicate stress or health status – it must be evaluated alongside symptoms, daily profile, and other lab markers.
