Hi, My latest PSA test was "undetectable at <0.05"? Is it reasonable to insist on a more precise result to better gauge my risk and prognosis? My MO at Stanford said this is their standard ultra sensitive test and I should continue it at their lab.
I've noticed many of you reference scores between 0.05 and 0.01 hence I'm wondering where I am in that spectrum.
A more precise score probably wouldn't change my immediate treatment plans (EBRT + 12-18 months of ADT+Zytiga), but I've seen some studies that show better odds based on nadir so I assume a <0.01 is better than a <0.05.
Thanks in advance for any insights.
Here's my story....
6/18 - 52 at diagnosis. Dx with PSA 10.8. GS 4+3.
8/18 - RALP@Stanford. -margins,-nodes(0/15), -bone, -Ga68 PSMA/PET scan. PT2NoMo.
9/18 - PSA 4.0!
11/18 - PSA 4.5!!
11/18 - Axumin & 2nd review of original PSMA 68Ga scan id 2 suspect pelvic nodes. Started Lupron.
12/18 - PSA 0.37. Started Zytiga+Prednisone. Started EBRT (35 fractions, 70 & 50 gr.)
1/19 - PSA <0.05
