Find Answers to General Questions

Have CLSI's document codes changed?

As part of an initiative to better classify our library of documents, some CLSI documents were assigned new codes to reflect their categories. Find out more here.

How often does CLSI update documents?

Approved consensus documents are reviewed between three and five years after publication. If a technical or environmental change warrants it, any document may be updated before the scheduled review date. At the close of each respective review period, the committee considers and responds to the comments and revises the document appropriately. Following approval by the appropriate consensus committee, the consensus document is published at the next level.

How can I receive a copy of the CLSI catalog?

CLSI encourages you to view the online catalog or to shop online. The printed version of the CLSI catalog is distributed periodically. To receive a hard copy of the catalog, please e-mail customerservice@clsi.org.

Are CLSI standards and guidelines mandatory?

CLSI develops and publishes standards and guidelines through a consensus process that involves representatives from government, industry, and the health care professions. Because of the unique credibility our threefold consensus process gives to our documents, regulatory agencies or accrediting bodies often require that a specific CLSI standard or guideline be followed. In these cases, following the standard or guideline becomes mandatory for institutions aiming to meet given regulatory or accreditation requirements.

What does CLSI/NCCLS stand for?

The organization changed its name to Clinical and Laboratory Standards Institute (CLSI) in January 2005. The acronym NCCLS stood for its previous name, National Committee for Clinical Laboratory Standards.

How do I find the most recently published documents?

When viewing our Online Shop, you will see a Featured Product category, that will feature our most recent publications. Members also receive our eNews Newsletter which will always announce new documents and products.

Why did CLSI make the change from ESS to web-based eCLIPSE?

We found that eCLIPSE is an easier system to use with many more features that our members enjoy. eCLIPSE allows our members to perform more advanced searches, view new documents as soon as they are published, print documents, and administrators may create usernames and passwords. Members with access can sign into their eCLIPSE account.
