Is it true that both Johns Hopkins and Mayo recommend use of standard psa test rather than the ultrasensitive psa test for post-prostatectomy monitoring of psa levels? I have heard that but don't know for sure whether it is true (or only in certain cases?) I read so much about ultrasensitive results (and the anxiety they cause), but these two institutions are not fully of dumb people, so it would be interesting to know their thinking.
