PSA

Prostate-specific antigen. A 34-kD glycoprotein serine protease (formally, kallikrein-related peptidase 3) encoded by KLK3 on chromosome 19q13.41, which has significant homology with other neutral proteases. It is secreted exclusively by the prostate epithelium and is responsible for lysing the seminal coagulum; it is present in the serum and is increased in patients with both benign (acute inflammation and BPH) and malignant (cancer) prostate lesions;. Most serum PSA is bound to protease inhibitors, including alpha1-antichymotrypin (the form usually measured in the lab), alpha1-macroglobulin, and in far lower amounts to alpha1-antitrypsin; small amounts of PSA in the circulation are not bound—i.e., free—to a carrier protein. Prostate cancer is present in 22% of those with PSA levels above 4.0 µg/L, and 60% of those with levels above 10 µg/L.

Patient discussion about PSA

Q. Would kidney stones affect a PSA reading? Would drinking lots of grapefruit juice affect a PSA reading? My husband's PSA reading jumped from a 4.2 to a 17 in @ 2 years' time. How can that be? This man takes all sorts of supplements and really watches his diet. He also takes good care of his body, and does NOT look or act 68.

A. You should get your parathyroid gland checked out. Your calcium level might be causing the kidney stones.

Q. Rising PSA to 10 with two negative biospies? Expect cancer? 67 yrs old in good health otherwise.

A. High values don't always mean it's cancer. At 67 years old, you're prostate is most likely enlarging, resulting in the higher PSA results. And after two negative biopsies, it sounds like you're in the clear. Like Brandon said though, keep up with your regular check ups.
