Dianaq,
The Oncotype DX test is a test on the tissue of your tumor that was removed.
You have a tissue sample via slide sent to genomic health in Calif. They do the test is cost $3,400 this was covered by my insurance company.
here is the link

What is found on your path report is your KI-67 level, mine was high 40%
Dr. Slamon believes this is a very important feature. He felt since mine was so
high I did not even need the Oncotype test with KI-67 levels that high.
I am still glad I did the test to confirm my status.
Hope this helps if you need any other info just reach out to me.
Good Luck
Jean
