Second Notice

C34-A2—Sweat Testing:  Sample Collection and Quantitative Analysis; Approved Guideline—Second Edition (Reaffirmation)
The "sweat test," a quantitative measurement of chloride in sweat, is used to confirm the diagnosis of cystic fibrosis, but has been reported to have unacceptably high false-positive and false-negative rates.  This document provides much-needed comprehensive guidelines addressing the collection of sweat and the quantitative measurement of electrolytes in sweat.  The deadline for the completed ballot for C34-A2 to be received at CLSI is 5 July 2005.

Reaffirmation of a CLSI document is appropriate when the area committee determines that neither comments received nor any other substantive reasons support changes.  As with other candidate-for-advancement documents, only delegates from Active and Associate Active member organizations may vote, using a ballot found on CLSI Forums.   

Ballots are posted on the Forums section of our website, available to Active and Associate Active members.  Login to Forums to access the candidate-for-advancement forms, and send your completed ballot to the CLSI by the listed deadline.

Under our Administrative Procedures, a CLSI document approved by the area committee at the first level of the consensus process is submitted to delegates as a “candidate-for-advancement” consensus document. This begins the voting and approval period by the delegates.

Remember that we welcome and encourage comments from our voting members at each publication stage.  Comments on a candidate-for-advancement consensus document will be addressed by the committee prior to advancement.  In each document edition, a summary of comments on the prior edition is included, along with committee responses.
