[Histonet] HER2/NEU

[Knutson, Deanne]

I just wanted to see what others in the histology world might be experiencing.

We have seen a marked increase in the percentage of HER2 cases resulting as Indeterminate, when
we compare our last year patient predictive marker results to this year's results.
The clone we are using is CB11 from Cell Marque.

We did a HER2 study last year where we sent out our cases for a second opinion, and the study showed
others interpreted our Indeterminates as that also.
Has anyone else also noted this increase in their annual comparison, and what clone are you using?

It is so nice to be able to reach out to our peers with these types of questions.
Thank you for responding back!
