About CLSI


Our Standards Set the Bar for Laboratory Excellence

Learn why the health care community turns to CLSI standards for trusted guidance on continually improving laboratory testing quality.

The difference is in how our standards are created.

CLSI provides a forum for members across the global laboratory health care community to openly collaborate on challenges facing clinical laboratories today, unifying their voices to develop standards that reflect equal representation from government, industry, and health care professions.

Due to this consensus-driven process, the standards created and delivered through CLSI are widely upheld as the “standard” to turn to for timely, reliable, globally applicable clinical guidance—and become the trusted foundation on which laboratories can confidently develop operating procedures, industry can build their regulatory data packages, and government bodies can base their regulation.

By applying our standards in practice, laboratories can improve accuracy and reduce risk to increase the quality of test results, leading to better medical outcomes for all.
