0.01 is the lower limit of the test, and as you say, is minimal. At this point, he should not even be having an ultrasensitive PSA test. He would not do anything unless his PSA rises above 1.0, and possibly not even then, so why subject yourself to such anxiety?

Wonderful. That's where we are leaning, but wanted another opinion.

Tall-Allen - as usual is correct. My RO has me do a PSA every six months, but the assay only measures PSA that surpasses 0.09, which will indicate failure. I'm at 3 1/2 years post-radiation. The 0.01 seems pretty darned low, as Tall_Allen notes.

The docs are really good at eradicating it up front with enough notice, and there is a ton of research when things get pretty far down the road....but this biochemical recurrence grey area in the middle can drive you crazy. Since he had an RP, technically he has not reoccured until he reaches 0.20. After that the doubling time matters. There are newer PSMA Pet scans that can potentially pick up the source of the PSA if he is at least 0.30, but alot of docs seem to want to wait until its at least 0.80. I personally would stick with the upsa test and if it continues to go up you can use the time to start looking for a good medical oncologist that specializes in PCa. Don't expect alot of action though until either 1) they locate the source of the PSA or 2) your husband rises to a certain level and your doubling time is short.

An isolated PSA value has a miniscule information content. If you want to prognostisize on things to come, you should wait until it breaches 0.06, where the rounding error comes into par with the test's accuracy. It is true that nothing will be prescribed even at that level, but by calculating a PSA doubling time you will get a glimpse of its aggressiveness.

My oncologist checks me monthly , he has the test that goes to <o.x , he calls my monthly <0.1 as undetectable.

High school maths suffice for translating this to less than or equal to 0.04. 0.05 or more rounds up to 0.1 (without the less symbol).

The PSA is still very low . The new PSMA PET/CTs have a detection rates of about 50% when the PSA is around 0.2.

If his PSA continues to increase, IMHO , get a PSMA PET/CT when the PSA is around 0.5 and see if the test detects any lesion. Many treatments are possible to control the cancer if there were mets .

The interval to measure the PSA is related to the PSADT. My PSADT is around 3 months and I have monthly PSA determinations.
