Diagnos-Techs, Inc. was established in 1987 and was the 1st lab in the United States to implement salivary based hormone assessment into routine clinical practice. For the past twelve years, our tests have converted many physicians in their preferences from run-of-the-mill mass production panels to precision diagnosis of problems. These tests have become powerful tools in evaluating gastrointestinal problems, stress and hormone related diseases and the overall wellness of the patient. Quality control is our primary goal. All parameters on our reports are standardized daily to WHO (World Health Organization) and other standardization agencies' reference materials. This insures the reproducibility of results, and permits precise clinical diagnosis based on real values, year in and year out.
