I was relieved to get my PSA result 6 weeks post ORP as "undetectable", but also found that it was reported as "less than 0.05", which evidently is the margin of detection used by that lab.
Is there any relevance or significance to demonstrating that it's lower than that? I've seen where people report levels lower than than that ("0" or "0.01"), but I presume that there is no real reason to define it more accurately at that level.
My urologist mentioned, incidentally, that PSA as a measure of disease is likely to be phased out in the next 2 years and replaced with a more specific test of some kind.
Open RP 5/29/07
T1c, Gleason 7 (contained lesion, negative nodes)
PSA 7/7/07 - undetectable
