Decipher Test

I had my third biopsy in the past 18 months in September - this one at the Mayo Clinic in Jacksonville. I have asked for a Decipher Test each time, but so far no luck getting it. I am 66 years old, gleason 4+3 on the last biopsy. When I asked the urologist at Mayo for the test he told me that the test is for people who have had a prostatectomy. I know that is not true. I feel like he has already made up his mind what my treatment should be and does not want any information that might contradict him. Has anyone else had trouble getting a urologist to order the test? It seems like it should be automatic after a biopsy.
