PSA levels can be detected in the blood, urine, or semen. Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated.
Age 60 or older: should be at or below 4.0 mg/mL. Age 59 or younger: should be at or below 2.5 mg/mL. The average PSA for men in the younger group is <1.0 mg/mL. Why are my PSA levels elevated? Your PSA levels could be elevated for many reasons.
Normal PSA Levels: 0 - 4 ng/mL; Slightly Elevated PSA: 4 - 10 ng/mL; Moderately Elevated PSA: 10 - 20 ng/mL; Highly Elevated PSA: 20+ ng/mL; PSA Levels by Age Chart (Free to Total Ratio)
Cells in your prostate make a protein called prostate-specific antigen (PSA). A PSA blood test measures the amount of PSA you have circulating in your blood. The amount of PSA your cells make ...
The PSA test can detect high levels of PSA that may indicate the presence of prostate cancer. However, many other conditions, such as an enlarged or inflamed prostate, also can increase PSA levels. Therefore, determining what a high PSA score means can be complicated.
Experts consider PSA levels below 4 nanograms per milliliter (ng/mL) to be typical for most people. Anything higher may indicate that you have cancerous cells in your prostate gland. But...
The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent to a laboratory for analysis. The results are usually reported as nanograms of PSA per milliliter (ng/mL) of blood.
The PSA test is a blood test that measures a protein that is produced by normal healthy prostate cells and cancerous prostate cells. PSA levels in the blood are often high among men with prostate cancer, but there’s no clear-cut abnormal or normal PSA level because it can vary from person to person.
A PSA level between 4 and 10 means you have over a 25% chance of having prostate cancer. If you have a PSA level greater than 10, you have over a 50% chance of having prostate cancer. It’s very important to talk to a healthcare provider about a prostate biopsy if your PSA is in these ranges.
This chart shows how PSA levels change with age, and how various risk factors can inform your decision-making process when discussing prostate cancer testing with your doctor.
