Benefits of CLSI Membership
By participating in CLSI, members don't just use standards. They help shape them, strengthening both their own operations and the laboratory ecosystem as a whole.
"CLSI is unique because it enables people from academia, hospitals, industry, and government to collaborate to develop standards and guidelines for the medical laboratory community. CLSI has an impact on laboratory medicine, not only in the United States, but also in many other countries around the world, particularly in middle- and low-income countries that lack the funding and experts to develop their own guidelines."
