What should I know about cortisolspiegel testen?

The query about cortisol testing is not directly covered by the provided context. In general, cortisol (the 'stress hormone') is measured in saliva, blood, or urine. A single value is not informative; the diurnal rhythm is key. MyBody-X offers hormone tests that may include cortisol, but these are screening tools, not diagnostic for conditions like Cushing's or Addison's disease. Evidence for home cortisol tests is moderate: they can detect deviations, but interpretation requires medical guidance. Confounders include stress, sleep deprivation, and medications (e.g., corticosteroids). An elevated cortisol level alone does not confirm disease. If symptoms persist (fatigue, weight gain, hypertension), consult an endocrinologist. MyBody-X labs are ISO-certified, but clinical validity of home cortisol tests is limited. Evidence: practice/mixed.
