I have done plenty of research as well as ask my Dr.’s about the minimum level of detectable PSA for an ultrasensitive PSA test. It seems like there is a lot of contradictory info out there. I just received my latest psa test result of 0.025 - 18 months after my SRT. The PSA seems to hang right around the 0.025 for the last 3 tests (9 mos). I know this is undetectable <0.1 which is good, but what is the minimum detectable psa? Is it 0.001? I have all tests done at LabCorp and can’t seem to get an answer from LabCorp.
What have been some of the lowest PSA values you guys have seen.
