  • Cortisol (4x in one 24 hour period)

Recommended with situational stress and fatigue; indicator of adrenal imbalance. Tests morning, noon, evening, and nighttime cortisol.

Advantages to saliva testing:

  • Saliva testing, unlike serum tests, measures the bioavailable (“free”) levels of steroid hormones
  • Samples are collected at home, allowing for precise timing of collection, especially for cortisol, which must be measured at specific times of the day or night
  • Saliva collection avoids the stress of a blood draw, which can affect levels of cortisol
  • Hormones are stable in saliva at room temperature for up to 2 weeks, allowing for worldwide shipment and convenient mailing of samples for testing
  • Saliva testing is less expensive than conventional serum testing
