Prostate Specific Antigen Blood Tests

The Prostate Specific Antigen (Total) test is a blood test that measures the levels of a protein called prostate specific antigen (PSA) in the blood. PSA is produced by the prostate gland, which is a small organ located in men that helps produce semen.

This test is commonly used to screen for prostate cancer, which is a type of cancer that affects the prostate gland. High levels of PSA in the blood can be a sign of prostate cancer, although it can also be caused by other conditions such as an enlarged prostate or an infection.

By measuring the levels of PSA, doctors can assess the risk of prostate cancer and determine if further testing or treatment is necessary.

It is important to note that this test alone cannot diagnose prostate cancer, but it helps doctors make informed decisions about a patient's health.
