Advantages of Saliva Testing


  • Measures the bioavailable ("free") levels of steroid hormones, correlating with symptomatology and potential deficiency.
  • Samples are collected by the patient at home, allowing convenient timing of collection especially for cortisol, which must be measured at specific times of the day or night.
  • Hormone levels can be assessed during topical hormone supplementation.
  • Convenience of collection allows frequent sampling (during a menstrual cycle, fertility problems can be determined).
  • 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 shipment and convenient mailing of samples for testing.
  • Saliva testing is less expensive than conventional serum testing.
