Great news on your PSA. Many labs have different values of what they consider undetectable and how low they will list numbers.

My last PSA test was .10 My PCP stated that at Mayo lab Jacksonville that anything below .10 was considered undetectable and you would not get numbers below that just the symbol that is below .10 Don't know what your lab sets as numbers, but from my expereince with PSA testing you are very low. One thing my urologist, R/Os and PCP warned me was to make sure I had all my PSA test done at same lab.

They stated can have different results with same blood and some use different classification of undetectable and also how far down the numbers will be listed numbers. I only had one bump up (was told completely normal it is what happens over time) and all rest over my 2.5 years and every 3 months PSA test went down.

I did not have RP or hormone treatment so very happy with my .10 I was told by my R/O was to have a PSA that stayed below 1 So I am way below that and my doctors like me are all happy.
Good luck and again try to stay with same lab doing your PSA tests.
