Abstract The hypersensitive prostate specific antigen (PSA) test can measure in 0.01 ng/mL units, and its efficacy for screening after radical prostatectomy (RP) has been reported. In this study, we assessed patients who underwent RP to evaluate whether the nadir value affects biochemical recurrence (BCR). I have a lot of PSA anxiety, rightly so, since this is what led me to surgery in the first place! I may first go with the normal PSA. If I am lucky enough to get "< 0.1 - undetectable" for one or two PSA tests, I feel I can always switch to the ultra-sensitive variety at a later time. I understand your anxiety over this. It is being debated whether prostate-specific antigen (PSA)-based screening effectively reduces prostate cancer mortality. Some of the uncertainty could be related to deficiencies in the age-based I have noticed, after following a number of signatures from other members, that the lowest ultra-sensitive level is achieved on the first test after surgery. This assumes that sufficient time has elapsed to to allow for the prostate-generated PSA to decay away. Some men eventually experience a biochemical recurrence, reaching .2ng/ml. It tells you something about the lab. In the case of your result the smallest PSA the lab will report is "0.03" ng/ml. If it has said "<0.1 ng/ml" it would also be an undetectable result but one from a lab that does not report ultra-sensitive results. The labs machine will not detect any thing below .03 and above. Many conditions can cause an elevated PSA. Though there is always some risk of the PSA test resulting in a "false negative" (a normal PSA reading when cancer is present), an increase in PSA levels may result from: A prostate gland biopsy; A resection of the prostate; Rigorous physical activity related to the prostate (i.e. bicycle riding) .
