About Us

In 1989 Diagnos-Techs was the first laboratory to introduce salivary-based hormone testing into routine clinical practice - creating a powerful tool in evaluating stress and hormone-related disease and illness. In 1995 Diagnos-Techs added salivary-based gastrointestinal and food allergy testing. Diagnos-Techs has continued to refine and improve its testing standards, using cutting-edge technology and methods. Our commitment to assisting health care professionals in restoring patients’ health and wellness is unsurpassed with over 1.2 million specimens tested per year.
