Elevated PSA levels can be caused by prostate cancer, an enlarged prostate, inflammation of the prostate, a urinary tract infection, advanced age and ejaculation, explains Everyday Health. Inserting a catheter into the bladder, a prostate or bladder exam, and a digital rectal exam also elevate PSA l


According to the National Cancer Institute, a normal prostate-specific antigen result is generally considered to be below 4 nanograms per milliliter. Doctors often recommend a prostate biopsy for men with higher PSA levels to determine whether prostate cancer is present.


There is no normal or abnormal level of prostate-specific antigen, or PSA, in the blood, according to the National Cancer Institute. Historically, doctors consider levels of 4 nanograms per milliliter of blood to be normal.




Free PSA, or prostate-specific antigen, is PSA circulating unbound and by itself within a man's body. Total PSA is the sum of unbound PSA and PSA bound to other substances circulating within a man's body, according to MedicineNet.com.


The prostate-specific antigen, or PSA, test measures the level of the prostate-specific antigen present in a man's bloodstream; PSA is a protein made by the prostate gland. Elevated PSA blood levels may indicate prostate cancer, though other conditions also cause high PSA levels, according to the Na


An elevated PSA level may indicate prostate cancer, enlarged prostate, or urinary tract or prostate infection, according to MedlinePlus. Patients who have recently had a urinary catheter inserted or who have had tests or procedures involving the bladder or prostate may also have an elevated PSA leve


There isn't a prostate-specific antigen level that is considered normal or abnormal, explains the National Cancer Institute. Generally, higher PSA levels increase the likelihood of prostate cancer, or if PSA results rise continuously over time, the risk for cancer also increases.


In the past, a PSA of 6 may have indicated the presence of prostate cancer. However, according to the National Cancer Institute, new research indicates that healthy prostate function can produce a PSA of 6 or higher.


An increase in protein-specific antigen (PSA) levels may be associated with many medical conditions that can affectthe prostate gland, such ascancer, benign prostatic hyperplasia, prostatitis and an infection. Another factor that alsomay raise the PSA level is the aging process, relates MedicineNet.
