Good afternoon Cindy,

For our stability dept, and to keep our R&D and QC depts compliant and 
happy, we have all of our stability samples testing within 7 working days from 
the day it comes out of a chamber.  For example, if a sample comes out on 
Monday, it would not have to have its analysis completed until the following 
Wednesday.  This is in our SOP.  We are a CRO facility and do work for cGLP 
and cGMP stability testing. We have never had an issue with our stability 
testing procedure.  I would like to comment and state that I have seen other 
cases where depending on when a sample is pulled from the chamber, typically 
anything 3 months or less, has to be analyzed within a week and then 
anything over 3 months, you have 2 weeks to a month to complete analysis.  
If you have any questions regarding my comments, please do not hesitate to 

Best Regards,
