It has been ten years since I had a radical prostatectomy (with negative margins). At my surgeon's suggestion, I have had yearly "total" PSA tests since then but not since 2019 so I'm overdue. The results so far have always been reported as <0.1 ng/mL without knowing what, if anything, is happening below that level. Quest, who owns the labs in my area, also has a more sensitive "Post Prostatectomy" test which measures down to 0.02 ng/mL but I've never had that test.
Is there an advantage to getting the ultrasensitive PSA instead of the total PSA? Knowing just that the result is less than 0.1 seems a bit like a dummy light on a car that goes on only when things really need attention. Maybe its better to know what, if anything, is happening at a lower level than 0.1?
At what PSA level would treatments be considered? If it's not until the PSA is over 0.1, then it makes sense to stick with a total PSA test and not know anything below that level, even if it is increasing.
I know an ultrasensitive test might cause unnecessary anxiety but, if I see it slowly increasing year after year, then it would be safe to assume there is still prostate cancer somewhere and it will eventually be over 0.1
Thanks for your suggestions.
