The National Comprehensive Cancer Network (NCCN) offers an excellent online document called "Practice Guidelines in Oncology--Prostate Cancer Early Detection." Find it here:
http://ccme.osu.edu/docs/20090218_ProstateDetection.pdf
Shortcut to page 7, which says that a positive DRE should be followed by a biopsy, regardless of PSA results.
Hope this helps...

I re-wrote my original posting. I originally posted about getting a "% free PSA" test, but then recalled that this test is for patients in the "diagnostic gray zone" of between 4 & 10 ng/mL. I deleted everything I wrote about the "free PSA" test, and left only info on the NCCN document.
