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:
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.
