I do not think this is the adequate forum to ask this question because you may get a wrong answer that could determine your decision.
Your pathologist is the one who should decide about this issue.

Subject: [Histonet] Minimum sample size for breast markers
Is there a minimum number of cells that should be present when testing for ER, PR and Her2? I have looked on the CAP website but cannot see anything about this. We are constantly getting these small biopsies or FNAs for testing and I sometimes wonder what the lowest threshold is for testing...20 tumor cells, 50 tumor cells???? Any information would be appreciated. Thanks in advance for your help.
