A Committed Membership Base

Our members help support volunteer committee work and encourage their staff to participate on document development committees. Members are also asked to 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.

Membership Options

An Unmatched Volunteering Experience

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 information from their own laboratory work to create documents used by the medical laboratory community to improve processes, pass and maintain accreditation, meet regulatory requirements, and more.
