Prostate Specific Antigen (PSA) Total

The PSA Total (Prostate-Specific Antigen) test is a vital screening tool primarily used to monitor prostate health and detect potential abnormalities, including prostate cancer, at an early stage when treatment is most effective. Because PSA is a protein produced by both cancerous and non-cancerous tissue in the prostate, measuring its concentration in the blood helps clinicians distinguish between routine age-related changes, inflammation (prostatitis), benign enlargement (BPH), or malignant growths. Beyond initial screening, the test is indispensable for monitoring the effectiveness of ongoing cancer treatments or checking for recurrence in post-operative patients, providing a non-invasive early warning system that can significantly influence clinical decision-making and long-term outcomes.
