Flexi
I have always had my tests done at the hospital, even though our local phlebotomist centre send them to the same Hospitial lab. The small rise could be the machine. My PSA was 0.03 for the first year or so then started to fluctate but was slowly rising to 0.13. I have never got past three month testing, I was told it was still low and may be because of all the stricture surgery, something you also know all about. I did wonder if the ISD could be having an effect. Have my next test in a couple of days and see my consultant next week.
Certainly you should at least try for three monthly testing.
Thanks Chris
