About Us


DiagnosTechs was the first laboratory to introduce saliva hormone testing into routine clinical practice after being established in 1987. In 1995, DiagnosTechs added saliva and stool-based gastrointestinal and food sensitivity testing, which set us on our current growth trajectory. Today we operate throughout North America and globally by providing direct service through network providers around the world with more than 1.2 million specimens tested per year.

Each test we offer has been proven and validated in our research and development department. Our commitment and continual investment in cutting-edge technology and research talent ensures that we will continue to lead the market for noninvasive testing into the future.


The mission of DiagnosTechs 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 others 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.
