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.

PSA levels can be measured in the bloodstream, and elevated PSA levels can sometimes be a symptom of prostate cancer. So, this antigen gives doctors a starting point to evaluate your risk of having that disease. But what constitutes a normal PSA level? Why might your PSA levels be elevated?
Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. 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.
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.
A PSA level of 10 ng/ml or higher means you have a greater risk of prostate cancer. How serious is an elevated PSA? It depends. Your PSA levels will vary according to your age. A PSA level that’s higher than expected for your age range may indicate you have a condition that affects your prostate.
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.
