What steps are necessary?
Submitting a Sample
When submitting a sample for the Oncotype DX® assay, please choose the one block with both the greatest amount/area of invasive breast carcinoma/associated stroma and the least amount of non-invasive mammary epithelium (in situ carcinoma, hyperplastic epithelium, normal epithelium).
All specimens must be labeled with S barcode labels from the Oncotype DX Specimen Collection and Transportation Kit Box for that patient.
While the Genomic Health laboratory can accept tumor blocks and unstained slides, blocks are preferred due to the frequent requirement for manual microdissection of the specimen consistent with clinical trial experience.
