About Us

Established in 1987, Diagnos-Techs, Inc.™ Clinical & Research Laboratory in Kent, Washington is considered the leading international salivary-based testing and research laboratory. In 1989, Diagnos-Techs was the first laboratory to introduce saliva hormone testing into routine clinical practice, creating a powerful tool for evaluating stress and hormone related disease and illness. In 1995, Diagnos-Techs added saliva- and stool-based gastrointestinal and food sensitivity testing.

Diagnos-Techs continues to refine and improve our 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.
