My PSA testing regimen is thus:
GP gives me some blood test forms and I choose when to have one. Originally it was every three months, then four months and now two years post-op - with undetectable PSA at every test - I am thinking about extending to six months.
Make an appointment on-line with phlebotomist at local Chemist (I always book the 07.30 one, when they open).
PSA test result sent to my GP and to my IPad next day.
I seem to be very lucky as this system doesn’t seem to be available everywhere, as some men here report difficulties in getting tested, unfortunately.
If you do opt for active surveillance, do heed the words of “Matron” above, follow the testing regime she describes religiously, and chase up your doctors if you think they are not adhering strictly to the plan.
I hope you are on A/S for many years.
