The Total Prostate-Specific Antigen (Total PSA) test measures the level of prostate-specific antigen in the blood, a protein produced by prostate cells. This test is an essential tool for assessing prostate health, primarily used to detect prostate cancer, as well as to diagnose other conditions such as benign prostatic hyperplasia (BPH) and prostatitis. It is recommended for men over 50 years old, those with a family history of prostate cancer, or individuals experiencing symptoms indicative of prostate problems, such as difficulty urinating. The Total PSA test helps determine PSA levels, where elevated levels may indicate a potential issue requiring further investigations, such as a free PSA test or a prostate biopsy. Overall, the Total PSA test is a crucial tool for the early detection of prostate-related conditions, aiding physicians in making appropriate treatment decisions.
