To monitor inflammatory processes that can occur in the prostate gland, the physician should make the analysis of protein for free and total PSA. The rate of tumor marker PSA total and free should be no more than 4 ng/mg. If the amount of antigen ranges from the numbers above, this could mean the development of cancer.

What distinguishes the total PSA is of the free?

Total PSA differs from the free that is about 90%, while loose only about 10%. Total tumor marker in close connection with the secreted proteins of the prostate gland, is free not affiliated with them at all.

psaVegetables with a high nitrate content (cucumbers, pomidori, melons, watermelons), intake of chemical drugs (Cyclophosphamide or Methotrexate), and ascorbic acid is able to increase the number of antigens in the blood. In such cases, the patient is prescribed a prostate biopsy to confirm or exclude a terrible diagnosis – cancer.

On the accuracy of diagnosis may alsoto effect hemolysis of the blood sample, sexual relations, palpation of the prostate. It so happens that the test shows normal values of PSA, however, the patient still detect a tumor. For this reason, diagnosis must be confirmed by other tests.

  • CT;
  • ultrasound examination;
  • transrectal examination.
