Global Consensus-Based Leadership and Expertise

Through a consensus-based process, CLSI’s standards are developed and written by volunteer committees of leading experts in the field of laboratory medicine. Our volunteer committees share learnings from their own laboratory work to create documents and protocols used by the medical laboratory community to improve processes, pass and maintain accreditation, meet regulatory requirements, and more.

A Committed Membership Base

Our members help support committee work and encourage their staff to participate in document development. Members review, comment, and vote on CLSI documents before they are published—ensuring that the document development process is fair and unbiased and that everyone has a seat at the table.
