[Histonet] ER quantitative controls

[bamoe <@t> gundluth.org]

Hello all -

For those labs reporting ER results as quantitative (1+, 2+, 3+)  ---   two
questions:

1)  Does your control tissue show representation of the 3 different grades
- meaning that there is tissue staining as 1+, another piece staining as
2+, and a third piece showing 3+ staining?  Or do you simply show a
positive reaction?

2)  If you do show representation of 1+, 2+, 3+ could you please share your
process of obtaining control tissue?

Thank you for any comments!
