[Histonet] fixation documention for her2-neu

We are having quite a time deciding how we are going to handle documentation concerning fixation for specimens requiring Her2-neu IHC testing and interpretation.  What is the actual fixation start time?  Is it when the large specimen first has 10% formalin added or when the specimen is actually grossed and sections are taken?  The CAP guidelines were discussed in Denver at the NSH meeting and I understood that the start time was when the specimen was cut open or 'breadloafed' or when it was grossed in.  However, this is not stated very clearly by CAP.  What are you doing out there in Histoland?  Are you using a general statement on your reports to reflect processing within 6-48 hrs fixation, < 6-48 hrs fixation or > 48 hr fixation or are you actually documenting times when formalin was added, gross time, processor start and end times?
Please comment as I need to give my supervisor and the pathologists other perspectives on this controversial issue.
