Prostate-Specific Antigen (PSA) in Serum by Immunoassay (with Probe)

Why Is This Test Done?

Your doctor may order a PSA test to monitor prostate health, especially if you have symptoms like frequent urination, pain during urination, or an elevated risk due to age, family history, or other factors. It can also be used to screen for prostate cancer or evaluate treatment progress.

What Does a High PSA Level Mean?

Elevated PSA levels can indicate conditions such as benign prostatic hyperplasia (enlarged prostate), prostate inflammation, or prostate cancer. However, other factors, like age, race, or recent ejaculation, can also influence PSA levels. Results should always be interpreted by your healthcare provider in the context of your overall health.

What Does a Low PSA Level Mean?

Low PSA levels are less commonly associated with prostate issues but may occur in younger men or those with certain medical conditions. They can also be influenced by factors like low testosterone or certain medications. Your doctor will consider the full clinical picture.

How Is This Test Performed?

A blood sample is drawn from a vein, usually in your arm. The sample is sent to a lab where it is analyzed using an immunoassay method to detect PSA protein levels. This test does not require fasting or special preparation beyond standard blood draw procedures.
