Prostate-Specific Antigen is a protein produced by the Prostate Gland that is majorly passed into the Seminal Fluid, also known as unbound or free PSA. If the percentage of free PSA reduces in the Seminal Fluid, you can be at a high risk of developing Prostate Cancer.
This is a specially curated test for measuring the levels of free PSA and enabling you to take early actions if required.
