Kamic108: if it does not show it on your lab report, ask your BS. My biopsy report did not show what was used and I asked my BS (I can't remember now which one it was that he said would have been used). The pathology report from the surgery did, however, specify what test was used for the HER2 status.

Dx 11/5/2018, IDC, Left, <1cm, Stage IA, Grade 1, 0/2 nodes, ER+/PR+, HER2- Surgery 12/16/2018 Lumpectomy: Left Radiation Therapy 2/19/2019 Whole-breast: Breast Hormonal Therapy 4/14/2019 Tamoxifen pills (Nolvadex, Apo-Tamox, Tamofen, Tamone)

They do the IHC test first. It often comes back equivocal, so they'll re-test using FISH. It takes longer but is more definitive.
