What is a PSA value?

PSA is the abbreviation for the prostate-specific antigen. PSA is a protein and is mainly formed by the epithelial cells of the prostate glands and released into the seminal fluid. In the blood, PSA occurs in healthy men only in very small amounts. The PSA test is advisable from the age of 50 - unless there is already a familial burden of prostate cancer. In the case of family history, examinations are taken at the age of 45 years to determine the PSA value.

PSA test to determine PSA value

Before the examination you should neither ride a bicycle nor ride a horse and abstain sexually for 24 hours. Following the PSA test, the family doctor scans the prostate via the anus from the rectum. Total PSA (tPSA) should be less than 2.5 ng / ml serum. The PSA level usually increases with age, but should not exceed a limit of 4.0 ng / ml. Increased PSA values ​​occur at:

  • prostate inflammation
  • prostate cancer
  • after a biopsy of the prostate
  • after a massage of the prostate
  • after partial prostatectomy

Increased PSA levels in prostate cancer

If elevated levels of PSA are detected, additional diagnostic measures should be used to identify the underlying disease, as only a quarter of all men with PSA levels of 4 to 10 do have prostate cancer. PSA value is becoming more and more important as a test in cancer screening. Unfortunately, the PSA test as a routine check for cancer screening is not yet covered by the statutory health insurance.
