The next question I would like to address is "Is this method an approved or official AOAC method?". The answer to this question is "no" and any lab claiming to be using an approved AOAC method is clearly in the dark as to what that means. I suppose it would be appropriate at this point to define what constitutes an "approved" AOACmethod. AOAC basically has two types of "approved" methods that pertain to our industry. The first AOAC approved method level is what is termed the "Peer Verified Method" (PVM). This is a method that has undergone a single-lab validation and its performance has been checked in at least one other, independent laboratory. It is expected (at least by AOAC) that most PVMs will eventually undergo full interlaboratory collaborative studies (usually 10-12 labs) and obtain "Official Method" status which is the second or highest level of approval. http://www.npicommunity.com/Blogs/tabid/53/EntryID/51/Default.aspx editor@npicenter.com http://www.npicommunity.com/Blogs/tabid/53/EntryID/51/Default.aspx#Comments http://www.npicommunity.com/Default.aspx?tabid=53&EntryID=51 Sun, 28 Jan 2007 04:16:00 GMT 0 http://www.npicommunity.com/DesktopModules/Blog/Trackback.aspx?id=51
