[Histonet] RE: A Spreadsheet for ER/PR Benchmark Comparison

[McMahon, Loralee A]

Sorry folks I meant to say 20% not 5.  Use a spread sheet in Excel and a formula

Take your total number of Breast cases and divide by the postitive ER cases to get a percentage of cases.
Do the same for the PR and the HER2.
100 breast cases divided by 20 positive ER cases gives you a five percent positive.
 Your percent positive cases should closely correlate with the national average and published percentages.   You could make a pretty graph in excel to go with it, but I don't think that is absolutely necessary.
Hope that helps.

Good Afternoon All,
I am racking my brain trying to figure out how to show the requirement for CAP ANP.22970 patient results of ER/PR/Her2 with published benchmarks.  I have collected my data and I have my benchmarks, but I can't seem to wrap my head around how to collate it.  Any suggestions or spreadsheets anyone would be willing to share?
Thanks,
Wanda
