About Saliva Testing:

  • Saliva testing identifies bioavailable hormone levels – the active quantity that’s free to move into body tissue. Its non-invasive nature also make it the gold standard for tests requiring multiple collections, such as diurnal cortisol.
  • ZRT developed the methodology making saliva hormone testing commercially viable
  • Only lab to perform extraction — the accepted methodology for research studiesNo special shipment methods required
  • Samples are stable during shipping, even over the weekend and holidays

Suitable for:

  • Assessing “free” (unbound to carrier proteins) hormone levels
  • Monitoring hormone replacement given orally, topically, vaginally or via pellets
  • Determining diurnal cortisol levels (4 times during 1 day) for adrenal stress assessment

Not Suitable for:

  • Monitoring sublingual / troche hormone replacement
  • Patients with dry mouth, e.g. due to Sjögren’s Syndrome


*Please note, residents of CA, NY, and MD require a physician's prescription for lab tests.
