What happened with the PSA???

Blood test showed my PSA at 6.1 at a local military hospital  in Aug 05.  Set up appointment to uro the following week.  He does a, get this, urine test that shows me at 6.1!  That happened 3 times including my biopsy in Sep 05.  Talked to uro at the universty and blood test showed 4.5 in Nov same year.  Got another opinion at the V.A. hospital, and they're blood test showed 1.6!

What the heck is going on?  I've been studying PCa on the net since Aug 05 through today, and still have not seen or read or heard of any urine PSA test.  Also what's the difference in the lab doing the workup?  Seems there's a wide discrepency from 1.6 to 6.1 PSA readings.

Maybe there is a doctor reading this that will be able to answer this.
