LifePoint Receives Patent on Saliva Testing

"The use of saliva provides a quick, easy, and accurate means to measure comparable drug and alcohol concentrations in blood without the risks associated with the handling of blood itself,” said Linda H. Masterson, CEO of LifePoint.” The LifePoint Impact Test System allows rapid and meaningful diagnostic information to be obtained by virtually anyone anywhere, at any time.” A US patent entitled "Device for Detecting Analytes Related to Sample pH” has been issued to LifePoint, Inc. (Ontario, CA, USA), which has developed diagnostic tests that provide blood-comparable results from saliva analysis.

Previously, LifePoint developed and patented capabilities for the quick, easy, and noninvasive collection of saliva. When used with the company's patented flow immunoassay, this collection method is designed to provide rapid, accurate, on-site quantifiable results. The results mirror the levels of a variety of blood components, including drugs in many concentrations. In some situations, however, a component's correlation to an exact blood-comparable level is influenced by pH. When testing for such components in saliva, simultaneous measurement of the pH can help provide an accurate calculation of the corresponding level in the donor's blood. This ability to derive the blood concentration of an analyte by measuring both the saliva drug level and the saliva pH provides blood-comparable results without collecting blood.
