Pratoman, tested every 6 months at VA, and every 6 months at Urologist. There staggered, so every 3 months PSA test. Next PSA test at local Hospital. Explained to VA doc about the <.01 and got a
deer in the headlight look, same look Urologist gave me when I explained the 0.08.
Now I go to the Urologist (local hospital PSA test) in 3 months with the VA's 0.06. Who knows what the local hospital PSA test will be.
Both said should stay with one lab, yea which one ?
I'm doing both until something makes sense, <.01 and 0.08 is too much of a variance.
And think how much it gets our attention if we go from .01 to .02 or .03, we maybe even start considering some treatment options, when there are fluctuations like this. When maybe it means nothing or simply indicates some lab variance. Possibly a variance even within the same lab, or in this case with different labs. Which one are you supposed to believe?
I agree with Prato that it would be mighty interesting to have an immediate test at the other lab to see how they compare, without having to consider the possibility that you might actually have increased over several months due to who knows what( or for that matter actually decreased). That way if there was a big difference you could just say: OK it is simply a difference in the labs. Though, that would still not tell you which one you should believe. You are looking at a minimum variation of 8 to 1. Good grief! It does seem that much variation is unlikely to be your actual swings or ups and downs, seems most likely to be a lab issue, to me anyway. But what do I know? Nothing.
