Unexpected drop in PSA ?

Hi Bruce, after your prostatectomy, your body still produces a tiny bit of testosterone mostly in the adrenal glands, which can start to produce more when it's the bodies main source of production, but still in tiny quantities, a possible cause for your latest reading, assuming it's not just a blip; may be an issue with your adrenal glands,

I would add that all you numbers are extremely low numbers so the margin of error could be called in to play. Also what you did in the last couple of days for exercise could make a marginal change.

If you were tested everyday would that help or hinder?

I would love such numbers and my advice is to relax and get on with your day and dismiss any thoughts of PSA changes under 0.5 unless theee consecutive are upward.

Have a nice day

Hello Bruce (Bruceinpaf25275) 

I have posted a reply to this question in another thread:

 Raised PSA after operation 

I agree with Eddie (eddiel)  too - that's another reason!

Best wishes - Brian.
