I’ve just seen the results from my PSA test done on Monday.
My PSA is 2.3. I am 49 years old.
However the last test I had done was in 2014 and it was 0.7 then. Not had follow up chat with doctor yet.
Although my latest test is within the “normal” range for my age- should I be concerned at this stage about the velocity of change between the 2 tests?
Thanks
Nope. Just make sure you eliminate other, more usual causes of elevated PSA before you agree to a biopsy. Prostate Health Index (PHI) is a better test than PSA alone. No sex or bike riding 2 days before it.
Many thanks. It’s just that a jump of 1.6 in 4 years doesn’t sound good to me.
It's very slow. Probably BPH. Ask for PHI.
Am I right in thinking that a velocity of 0.75 / year or more is considered the red flag threshold?
No. There is no "red flag threshold." You are just making up things that will only increase anxiety. Stick with best practices and with what you know.
Tall Allen knows so much more than me, but you are correct that many reputable cited texts use a velocity of 0.75 / year as a very general guideline for being "worrisome" for cancer. Looks like you are half of that. So don't worry just yet, follow Tall Allan's and your doctor's advice.
You don't say if there was a specific reason for you to start prostate cancer screening early, nor when you started.
The United States Preventive Services Task Force periodically issues recommendations for various cancer screening procedures. I get the general sense that many (perhaps most) men here have not followed their recommendations, which continue to be very controversial among urologists.
But I myself don't reject their reasoning out of hand. There should be a reason you are getting a PSA reading. A broad reading of this may place your apparent alarm in context.

Also, try not to spend too much time on google--it's bad for sleep.
