Surprising that a Mayo doctor stated that < 0.1 is considered undetectable. My doctors consider anything measurable to be detectable, but less than 0.1 to be not actionable. Waiting for PSA to approach 0.20 before considered as a biological chemical recurrence and beginning next treatment.. However, measurements < 0.1 were used to track PSA doubling time and I was prepared for the next treatment as the PSA increased above 0.10

The standard for undetectable in a PSA test has been < .1 for the 14 years I’ve had prostate cancer., at least according to more than one doctor/oncologist I’ve been involved with
My very experienced MO at Johns Hopkins uses < 0.1 as undetectable. I live in Georgia and go to Labcorp and that is how they define undetectable. Nothing below that is actionable. I understand some wanted to see their PSA increase from a very low number and "be prepared" when it does reach >0.1 but the flip side to that is ignorant bliss until/if/when it reaches>0,1.
Each to their own.

My understanding is that different tests use different methods and have different ranges of reporting. Generally < x means that is the lower limit of the test used, so literally [on that test] the level was "undetectable." If another test has a lower limit of < 0.006, then 0.008 might be detectable [on this other test] but not "actionable."
