What does the "Retest Date" on List Labs Product Certificate Of Analysis mean?

Last Updated: Sep 27, 2018 11:56AM PDT
Thank you for your interest in List Labs.

On our more recent product Certificate of Analysis documents, you will find a "Retest Date" at the top right hand corner of the document.  Prior to this retest date, these products are retested for stability purposes.  If QC specifications are met, a new retest date is assigned; the Certificate of Analysis is revised and posted on List Biological Laboratories website,

If your product has a retest date that has lapsed, please check the new Certificate of Analysis on-line for updated information.  Please note that these dates are relevant only if the product has been stored as directed on the Certificate of Analysis.
