What Does a PSA Test Result of 6 Mean?

A prostate-specific antigen level of 6 nanograms per milliliter is considered elevated and may indicate an enlarged prostate, prostatitis or prostate cancer, according to WebMD. A patient with a recent history of urinary tract infection or urinary catheter placement may also have an elevated PSA level, notes MedlinePlus.

When interpreting PSA test results, doctors typically focus on both the PSA level and the trend of the level, including how much and how quickly the PSA level has risen. Men with PSA levels between 4 and 10 nanograms per milliliter have a 25 percent chance of having prostate cancer, states WebMD. A prostate biopsy may be necessary to evaluate for cancer if a doctor is concerned about an elevated PSA level.
