Total PSA
PSA (prostate-specific antigen) is a protein made by the prostate gland.
PSA (prostate-specific antigen) is a protein made by the prostate gland. Most of it goes into the seminal fluid, and a small amount passes into the blood. Total PSA is the sum of the free PSA and the PSA bound to other proteins in the blood. Retesting shows how it changes over time.
PSA naturally rises with age as the prostate grows. Ejaculation in the last couple of days, cycling, vigorous exercise and a recent infection can raise it for a while. Some medicines, such as 5-alpha-reductase inhibitors, lower it.
