I was diagnosed in 2002 at a major cancer center with IHC only, and at that time questions were just being raised as to the accuracy of testing for HER2. It looks like an attempt to standardize the quality of testing at a higher level may be gradually being put in place. However, I do think we need to recognize that this has taken a while and it is hard to tell whose testing has been accurate.
I will try posting a poll on the main forum to get some idea where we all are in terms of HER2 testing. Please consider participating in it.
