How to Order a Test

Ordering an Oncotype DX test and receiving the results is a straightforward process. Simply follow these 4 steps.

3Submit a sample

Exact Sciences can work directly with the pathology team (or the treating physician) to obtain a sample.

  • When submitting a DCIS sample for the Oncotype DX Breast DCIS Score® test, please choose the block with the greatest amount (cross-sectional area) of the highest-grade DCIS and the least amount of non-DCIS mammary epithelium (hyperplastic mammary epithelium, normal epithelium). While the Exact Sciences laboratory can accept tumor blocks and unstained slides, blocks are preferred.

  • Total mastectomy specimens are not appropriate samples for the Breast DCIS Score® test. In rare cases the diagnostic needle core biopsy may have more DCIS (cross-sectional area) than the excisional sample; if this is the case, then the needle core biopsy should be submitted.

  • All specimens must be labeled with S barcode labels from the Oncotype DX specimen collection and transportation kit box for that patient.
