MY FIRST PSA. It all started about a year earlier when my family doctor of 20 years retired. In the fall of 1994, my new doctor gave me a physical exam to establish a new baseline. The physical involved an assortment of blood tests, all of which were in the normal range, with one exception. The test called PSA came back with a result of 5. The acceptable range, according to the lab computer, was 0 to 4.

I didn't know what this test was. In fact, I don't think I'd ever had one before. My doctor's comment was, "It's slightly elevated. It's probably nothing to worry about, but I think you should see a urologist."
