My PSA results: .02 after 6 weeks; .01 after 6 months; .03 after 1 year.
Sometimes I just curse the concept of ultra sensitive technology, but I recognize that technology (DaVinci) created a better surgery.
Should I be worried or am I just projecting and creating my own anxiety?
Thanks in advance for your help.
I understand your anxiety, Ed. In PSA testing, and sometimes in the PSA lingo we use on the forum, it can be confusing to see numbers other than zero on your test results. It would be more accurate for us to write "undetectable" or less than 0.1 rather than "zero", but "zero" understandably sounds much more definitive.
Most urologists use the 0.1 ng/mL cutoff below which the PSA is considered negative. The ultrasensitive PSA test, as you know, measures to the neareset hundredth of a nanogram (0.01), so you may see results of 0.02 and 0.03 as in your case.
For the standard PSA, which measures to the nearest tenth of a nanogram (0.1), the lowest detectable value is 0.1 ng/mL, so anything below this, including your test values, cannot be measured.
I personally chose to have the standard PSA test for my followup testing, because it still measures accurately enough to catch any cancer recurrence, but eliminates the "noise" of values below 0.1 that can be measured, but that are insignificant.
I sleep better not knowing any numbers other than <0.1 ng/mL for my followup PSAs.
Take care and hang in there...Tim
