Ok all, follow up—radical prostatectomy 7 weeks ago. PSA just came back at 0.008. Does that mean there is some residual disease still present? I know I need to be patient and follow the PSA but has anyone had any experience with ultrasensitive testing? Is this anything I need to worry about?

Stop worrying. If your result was < .1 You would be considered undetectable. You are way below that. At this point, there is nothing to worry about. See what your follow up PSA test show in three months or so.

Almost anybody that finished a prostatectomy would be really pleased with your result.

@mks1111 You are doing fantastic, and your post probably reflects why Mayo doesn't do ultra-sensitive anymore.

That is great result !
Different labs have different cut-off numbers that they can measure and consider ultrasensitive.
Our hospital where my husband had RP does not go below 0.015 and WalkInLab has 0.014 etc.

My husband was gleason 9, so ultrasensitive is important , especially since our MO suggested that 0.05 should be trigger for having serious observation of the doubling time and if it is fast than salvage can start at 0.1 , or 0.15 latest.

For us it makes total sense and expecting results of PSA is never fun, no matter if it is ultra sensitive or not .

Wishing you forever undetectable PSA ! 😃🍀
