Prostate Specific Antigen (PSA) test

What is PSA?

Prostate-specific antigen (PSA) test is a non-invasive procedure used to detect the presence of prostate cancer in men. The PSA test measures the amount of PSA present in the blood, which is produced by the prostate gland. A high level of PSA can indicate that there may be a problem with the prostate, such as an enlarged prostate or prostate cancer.

The test is usually done along with other tests to diagnose and monitor treatment for any type of cancer, including prostate cancer. High PSA levels can be caused by:

  • Prostate cancer
  • An enlarged prostate
  • Other common prostate problems
  • Taking certain medicines
It is important to have regular check-ups and screenings for early detection and treatment of any health problems. There is no specific result. It depends on age, prostate gland size, and inflammation or infection.

PSA results by age

Generally: For men in their forties and fifties: An PSA score greater than 2.5 ng/ml is considered abnormal. The median PSA for this age bracket is 0.6-0.7 ng/ml. For men in their sixties: An PSA score higher than 4.0 ng/ml is considered abnormal.

How the test conducts

To conduct a PSA test, doctors take a small sample of blood from an arm vein or from the end of the penis. The level of molecules (PSA) found in this blood sample is measured, which can be used to detect prostate cancer or other health problems with the prostate gland. This procedure does not cause pain or discomfort for the patient and only takes around 15 minutes to conduct. Doctors typically measure both free PSA (PSA released in the blood) and PSA bound to proteins (PSA that has been "captured" in the blood). Free PSA is more sensitive, meaning it can detect cancer earlier. However, this may also mean that levels of free PSA are higher than levels of protein-bound PSA. While high levels of protein-bound PSA can still indicate problems with the prostate gland, they will not be able to detect cancer or other problems as easily as free concentrations.
