We have also tried to optimize the HER2 on the Ultra - our pathologists is not happy with how strong it is.  He is very concerned with over calling the positives and causing unnecessary treatments.   We currently use the Herceptest from Dako on a Lab Vision stainer but may have to eventually move to the Ultra.  We FISH all of our cases, but if the IHC is reported out as positive, then the clinician will put the patient on therapy which has serious side effects and is very costly.  If it is not truly a positive tumor, the patient should not be receiving the therapy.  A very difficult problem for us.
