Background
Human PSA, or Prostate-Specific Antigen, is a protein enzyme produced primarily by the cells of the prostate gland. Its primary biological function is to liquefy semen following ejaculation, which is crucial for sperm mobility and fertility. While most PSA is found in seminal fluid, a very small amount naturally leaks into the bloodstream. Measuring this serum PSA level through a blood test is a common tool for screening and monitoring prostate health. Elevated levels in the blood can indicate various conditions, including benign prostatic hyperplasia (BPH), prostatitis, or prostate cancer. It is important to note that PSA is not a perfect test for cancer, as levels can be raised by non-cancerous causes. Therefore, it is used alongside other diagnostic measures, such as the free PSA ratio, digital rectal exams, and imaging, to guide clinical decisions.
