[Histonet] ER/PR/Her2 control

[Dessoye, Michael]

Hello Histonet!

Looking for some advice regarding ER/PR/Her2 controls.  I'm able to buy commercially TMA blocks containing varying levels of positivity for ER, PR, and Her2.  This work nicely because you can have a negative and varying levels of positive control as a same-slide control.  But our docs would like to score Ki-67 as well.  Currently, they are just doing pos/neg for Ki67.

It will take some time to collect cases and create a similar control, so I'm wondering what y'all are using?  Is there anything commercially available?  Or is everybody just collecting cases with varying degrees of positive?

Thanks,
Mike
