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.
Approved consensus documents are reviewed between three and five years after publication. If a technical or an 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 technical committee, the consensus document is published at the next level.
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 firstname.lastname@example.org.
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.
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.
When viewing our Online Shop, you will see a Featured Products category that will feature our most recent publications. Members also receive our eNews publication, which will always announce new documents and products.
All of our corrections notices are available on our website and are dated. When you re-download a PDF version of the document, the watermarking on the bottom of the document will be dated. As long as the dated version of your PDF copy is after the date on the corrections notice, you are using the most up-to-date version.
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.
