CLSI Standards Documents for Public Review

Comment on New and Revised Standards Drafts

Help shape the standards that affect your day-to-day work. To preserve the integrity of standards developed through the CLSI consensus process, we seek input from the public on our in-process draft documents before they are approved for publication. Opening the dialogue to CLSI members and nonmembers alike, we encourage your involvement in shaping our documents to ensure all interested parties are given a voice.

General Information

Requests for documents should be submitted via e-mail to [email protected] or by fax to +1.610.688.0700. Comments related to CLSI draft documents shall be made in our commenting platform and shall be submitted no later than the comment deadline indicated below.

Limited Revision Process

The Limited Revision Process provides an expeditious alternative to the Consensus Document Development Process when the requested document updates meet defined criteria. Limited revisions do not result in changes to the document’s scope, purpose, and/or intended audience. The attached document includes revised (redlined) text, and only the revised text is to be reviewed and commented on. Comments pertaining to other portions of the document (ie, those that were not revised) will be held for the next full revision.
