On 5/9/11, my psa had risen to a detectable .2, which was a surprise.  Two weeks later (5/23/11) it was down to .16, so was wondering if there is any significance in the downward reading, even tho it is still "detectable".  Thoughts?

What did the .2 rise from? Was it the same lab? The standard is 3 consecutive rises. What I dont know is if by consecutive they mean every 3 mos or sis,boom ,bang. know what I mean. PCA information is like directions for any technical item, or building some thing. Something is always left out. Its maddening to me.

You'll want to do another test in a month or two....

I'm surprised my previous stats (always appeared below, previous posts) are missing.  But to answer, accordng to my memory, it had always been .05 or below.  That's about what it was 6 months ago.
 Yes, these recent readings are from the same lab.  That's the reason I had the 2nd psa blood work drawn.

Regarding the missing stats -- you may have just forgotten to check the 'Add signature" box , which is now off by default when you compose your message. (But it is on for a Quick Reply.)

I don't think you can read too much into the 20% reduction, although is is nice to have. There is a natural daily and weekly fluctuation in the amount of PSA we produce, and the lab may have used a different technician, equipment, or calibration.

Unfortunately, you are looking at a probable recurrence, but you won't know more definitely until your next test.
