An,
I have probably mentioned this in several threads, but my uro/surgeon did my first PSA at 7 weeks because of holidays. He normally does it at no sooner than 8 weeks, and he warned me that it might not be at the "bottom" yet, just to keep expectations in line.
As well, the clinic does only 1 decimal, so the "<0.1" I got at 7 weeks from them is "undetectable".
I took that and ran with it as a wonderful Christmas gift.
I didn't even know enough about ultra-sensitive to think I should ask for it until I came here (long after my surgery). When I did ask, the Doc said no - it only feeds anxiety. After my radiation, I did arrange to get the 2 decimal test, and got a <0.01. That was a little over 9 months out from surgery.
So was my 7 week PSA .01, .05, .09? Can't answer that.
I'd say take 0.02 as a good thing.
