About Us


Established in 1987, DiagnosTechs was the first laboratory to introduce saliva hormone testing into routine clinical practice. In 1995, DiagnosTechs added saliva and stool-based gastrointestinal and food sensitivity testing, which expanded the level of service we provide to healthcare practitioners and their patients. Today, we operate throughout North America and globally, offer direct service through healthcare providers, and process more than 1.2 million tests annually. Our commitment to research and ongoing investment in cutting-edge technologies ensures that we will continue to lead the market in noninvasive diagnostic testing.


Our mission as a clinical & research laboratory is to advance the cause and application of noninvasive diagnostic testing to restore health and improve the wellbeing of those we serve.


Our vision is to remain the clear leaders in noninvasive testing through research and development to fuel clinical excellence, innovation, validation, and deep partnerships with those who share our values.


  • Our foundation rests on our in-house research and development department.
  • We continuously pursue the advancement of noninvasive diagnostic testing.
  • We deliver unmatched service to our providers and patients.
