New episode alert - Currently Speaking on The Evolution of Oral Fluid Testing: From Early Adoption to the Future, with Mike Jeffries of ClearStar
In part two of this four-part series, Bill Current continues his conversation with Mike Jeffries of ClearStar, Inc. to explore the history, evolution, and future of oral fluid drug testing.
Mike shares his firsthand experience helping introduce one of the first commercially available lab-based oral fluid testing options to the employment market and discusses the early adopters that helped demonstrate its value. Bill and Mike also examine how oral fluid testing technology has advanced, including expanded testing panels, point-of-care options, and improved accuracy and reliability.
The discussion highlights the key advantages of oral fluid testing, including observed collections, reduced opportunities for specimen tampering, faster hiring timelines, recent-use detection, and its potential value in reasonable suspicion and post-accident testing. They also address the status of federally regulated oral fluid testing and why Mike remains optimistic about its continued growth.
