WSLH Proficiency Testing has been building a solid foundation for laboratory improvement since 1966. WSLH PT was developed by the Wisconsin State Laboratory of Hygiene to create proficiency testing programs that improved laboratory quality. Today, our mission has grown to providing proficiency testing services across the United States and around the world.
Based in Madison, Wisconsin, WSLH Proficiency Testing is the only PT provider that is a part of a national public health laboratory, and is affiliated with the state’s flagship higher education institution, the University of Wisconsin-Madison.
