About the PreDxTM Diabetes Risk Score

Tethys announced the expanded availability of its first predictive, personalized test - the PreDx Diabetes Risk Score - in June 2008. The PreDx Diabetes Risk Score (DRS) is a first-of-its-kind predictive tool that delivers an accurate assessment of an individual's risk of developing Type 2 diabetes within the next five years. The test is performed exclusively by the Tethys Bioscience Clinical Laboratory on routinely collected blood samples.

The new blood test is designed to help physicians identify patients at highest risk of developing Type 2 diabetes. The PreDx DRS is a quantitative in-vitro diagnostic test intended to aid in the assessment of a patient's risk for developing Type 2 diabetes within five years. This test is offered as a service by the CLIA-certified Tethys Clinical Laboratory and is performed on a fasting blood sample from patients at risk for diabetes. Risk factors include increased age, BMI, family history, hypertension, dysglycemia and dyslipidemia. The information provided by the PreDx DRS may be used by the physician in conjunction with other clinical indicators to develop an effective diabetes prevention program. The PreDx DRS is indicated for use as an adjunctive test to complement, not replace, other diagnostic and clinical procedures.

The PreDx DRS is not intended for the diagnosis of diabetes nor should it be used as the sole source of information when managing patients at risk of developing diabetes.
